How Is Alcohol Extracted From CBD?
This article is sponsored by Colorado Extraction Systems, a Colorado-based company with decades of expertise and knowledge in extraction, distillation, and evaporation equipment manufacturing.
Cannabis has been used by humans for thousands of years. Especially for medical purposes. It
was generally used to cure different illnesses and pains, primarily those of the muscle and bone
Today, CBD extraction is proving useful in various applications far wider than the original ones
where it sprung. However, unlike THC in marijuana plants, CBD is not psychoactive, meaning it doesn’t cause the “high” associated with marijuana.
The big picture is finding a reliable extraction method; it is crucial in producing a high-
quality and safe product without contaminants. Given that cannabis oil is a highly concentrated substance that contains more than just Cannabidiol (CBD), it only makes sense that the extraction process involves more than just one substance.
For example, when extracting essential oils from plants like lavender or peppermint, ethanol is
almost always used along with another substance like olive oil or coconut oil.
In essence, extracting CBD from cannabis is easy, if you know how to do it. Unfortunately,
there are a lot of things that can go wrong when extracting CBD from cannabis with alcohol.
That is why we created this article. It addresses CBD extraction with the aid of alcohol as the
main solvent. Let’s dive in.

Alcohol extraction from CBD
Alcohol extraction is very common in making cannabis extracts. The process is fast and
relatively simple. You can make a CBD/Cannabis extract with rubbing alcohol (isopropyl), but
the most common and safest solvents to use are ethanol or grain alcohol.
Alcohol is a polar solvent, meaning it will dissolve polar molecules—such as chlorophyll, the
a green pigment found in plants. To be more precise, it will dissolve them into the water portion of the solution. This is why you have to separate the two phases when making an alcohol extraction.
The more polar the solvent is, the more likely it will be able to remove chlorophyll from the plant
material and result in a cleaner extract.
Alcohol extraction is usually recommended for people who want a quick and easy way to make
a CBD tincture at home.
Alcohol extraction can be done with high potency cannabis flower or trim, kief or hash. You can
also use low-quality cannabis material to make your own low-potency edibles or topicals.
Ethanol extraction is preferred over other solvents due to its safety, cost-effectiveness and
versatility. The process of ethanol extraction involves soaking the plant material in ethanol (which acts as a solvent) to extract cannabinoids such as CBD, CBG, THC and others.
The soluble components are then separated from the plant material using a filtration process.
The components are then evaporated off using low heat to arrive at a concentrated extract.
The extracts obtained through ethanol extraction are amber in color and have a thick
Ethanol extraction can be carried out at room temperature or by heating the solution to enhance
cannabinoid extraction rates.
However, one of the major drawbacks of this method is that it also extracts chlorophyll from the
plant matter which leads to bitter-tasting extracts. Thus, a post-extraction winterization step is necessary to remove chlorophyll and any other lipids or waxes present in raw oil.
In addition, extracts obtained through ethanol extraction tend to be less pure than those
obtained through supercritical CO2 extraction or butane extraction.
Why is alcohol ideal for CBD extraction?
One of the most important things to consider when buying your CBD oil extract or CBD crystals
is the solvent used in its extraction process. The solvent that is used to make your product has a
direct impact on the quality of the end product you’re going to receive.
While there are several different types of solvents that can be used, one of the most popular
and effective solvents for extracting CBD is ethanol. Ethanol is a clear liquid and works well in
extracting cannabinoids from plant material.
Here are some more detailed facts about why ethanol is such an optimal choice for creating
Ethanol extraction is a simple process
If you’re looking for an efficient, uncomplicated method for CBD extraction, ethanol extraction is
for you. With this process, you can easily remove unwanted plant material from your extract.
This allows you to create a purer end product, which makes it easier to do whatever it is you’d
like to do with it, be it vaping it or using it topically.
Ethanol extraction doesn’t damage terpenes
Many other methods of extraction can damage beneficial terpenes found in cannabis, but with
ethanol extraction, this isn’t a problem. As long as your ethanol comes from food-grade sources.
Alcohol is cheap and available
First of all, alcohol is inexpensive, whereas other solvents such as butane are not. This is
because alcohol can be easily made at home with a still. On the other hand, butane must be
purchased from a chemical supply company.
Furthermore, the initial cost of purchasing a butane extractor can cost up to ten times more than
an alcohol extractor. Alcohol is also less expensive due to the fact that it does not require
purchases of new equipment.
Alcohol is safer
Moreover, alcohol is safer than other solvents since it evaporates at room temperature, making
it much less likely to cause an explosion during extraction.
Other solvents such as propane and butane require heaters which are more likely to cause an
explosion due to a higher chance of malfunctioning when used for long periods of time. In addition, there have been many cases where people have caused fires when attempting to
make extracts with butane inside their homes; therefore we do not recommend using this
method in order to extract your cannabis oil.
Lastly, it is an all-natural product that is widely available in varying strengths, which makes it a
great choice for this process. It also has been used for years as a solvent for various products
and ingredients, making it a natural fit for this application.
Butane vs. Ethanol
Why then would anyone want to use butane instead of alcohol?
The main reason is that butane extracts more CBD. In fact, it extracts much more than just CBD – butane will pull out everything except the water and a little bit of chlorophyll. And that’s important because there are many other cannabinoids besides CBD – THC, CBG and so forth.
But there are also many other chemicals besides cannabinoids – terpenes, plant waxes and so
forth. And those other chemicals will go into the butane extract too.
So when you make an extract with butane you get a kind of sludge that contains all kinds of stuff
you don’t want: waxes and chlorophyll and whatever else was in the plant. And some of those things may be dangerous or unpleasant – for example, when marijuana with a high THC content is made into an edible oil for eating on food.
Alcohol is the most preferred solvent for CBD extraction. It has a low boiling point, which means
that it evaporates fast. Since alcohol is flammable and hazardous, all the other solvents that have higher boiling points are not preferred. Isopropyl alcohol and ethanol are used to extract CBD.
The only difference between them is that ethanol is derived from plants whereas Isopropyl is
made from petroleum. Alcohol extraction is also known as the ethanol method because ethanol
creates a mixture of both water and alcohol in the ratio of 70% alcohol and 30% water.
When it comes to purifying ethanol, you need to remove the water content from it by using
different distillation techniques like molecular distillation, short path distillation, and wiped film
Ethanol Extraction for Cannabis and Hemp
Ethanol has a long history of extracting oil from plant materials for therapeutic use. In today’s highly competitive marijuana extraction sector, extraction artists have a wide range of extraction solvents to choose from such as carbon dioxide, light hydrocarbons (propane and butane), and ethanol. These solvents are used to extract the cannabinoids and terpenes from the cannabis or hemp resin.
What Is Ethanol Extraction?
Ethanol is more common than you think. Ethanol can be found in grain alcohol made by fermenting plant sugars from agricultural crops. Ethanol (C2H5OH), also known as ethyl alcohol, is a colorless and flammable liquid that can produce intoxication, be used for fuel, and also be used as a solvent. Ethanol can be fermented from different crops, but corn is the main source of ethanol in the U.S.
Ethanol extraction can be performed under warm or cold temperatures. Generally, raw and ground-up cannabis material (dry or frozen) is soaked in pre-chilled ethanol for a certain amount of time to separate the plant’s trichomes from the plant matter. Warm ethanol extraction has been a staple in amateur home extractions. For larger batches, room temperature or cooled ethanol can improve the quality of cannabinoids and terpenes in cannabis and hemp extraction.
After the initial extraction process using food grade ethanol, the solution is filtered and the ethanol is purged from the extract. Post-processing techniques gently remove ethanol from the extracts through evaporation. Ethanol may be removed with rotary evaporators, falling film evaporators, or a vacuum distillation system.
Winterization is a term used to describe the process of removing impurities such as plant lipids, chlorophyll, waxes, and fats from the oil. Chilling the oil and ethanol solution can cause these undesirable compounds to separate (precipitate) and rise to the top for easier removal. The cooling process can be performed in freezers, cold rooms, or other cooling equipment.
Keep in mind, ethanol has a higher boiling point than butane or propane. Because of its relatively higher boiling point, many of the terpenes that give cannabis the desirable flavors and aromas that many consumers enjoy, are lost in the ethanol extraction process. The inevitable loss in terpenes from the ethanol process also diminishes the entourage effect of the final ethanol extract product when compared to BHO extraction. Regardless of ethanol’s weaknesses, large-scale throughput and financing can easily overcome equipment limitations.
Ethanol extracts can also undergo a final polishing phase where adsorbents can be used to lighten the oil’s hue and improve the translucence of the extract. Popular adsorbents such as activated charcoal and bleaching clays can improve not only the color but also the quality of ethanol concentrates.
The residual ethanol is evaporated, condensed, and reused in the closed-loop extraction system to increase cost-efficiency and throughput. All of these operations take place in a lab-grade facility with adequate ventilation and storage areas.
Why You Should Choose Ethanol Extraction Over CO2?
Every extraction company favors one solvent over another for various reasons. Butane is the most common solvent used for cannabis extraction and CO2 extraction has also been touted as safe and eco-friendly. Ethanol extraction, however, offers both safety and efficiency when extracting cannabis or hemp on a large scale.
For high-volume extractions, ethanol can be the most efficient at separating cannabis compounds from the plant matter. Ethanol is an extremely polar solvent that can bind to cannabinoids, terpenes, but also chlorophylls and other water-soluble undesirable compounds. Many terpene boiling points are about the same as ethanol’s boiling point, thereby, increasing the risk of terpene loss when removing the ethanol solvent.
Ethanol’s polarity problem can largely be overcome with chilled ethanol (-40ºC or below) to bypass most of the chlorophyll, lipid, and other unwanted compounds. Under the proper conditions, ethanol extraction can produce isolate or limited full-spectrum concentrates with cannabinoids, and some terpenes, flavonoids, and other therapeutic compounds.
Ethanol can be easy to scale because using this solvent becomes cost-effective at a higher volume (1,000 to 5,000 pounds per day) compared to CO2 extraction, for instance. As hemp farming heats up across the nation, growers and extractors are looking for the most versatile and cost-efficient to reap CBD for a variety of infused products, not just CBD flower.
Is Ethanol Safer?
Ethanol extraction is no safer than hydrocarbon and CO2 extraction, that is to say, all extraction methods are safe for production under the approved building requirements. In fact, the Food and Drug Administration (FDA) has classified ethanol as a Class 3 solvent with low toxicity. Ethanol is one of the safest solvents for food grade and pharmaceutical extraction processes.
In pharmaceutical manufacturing, residual ethanol below 0.5 percent or 5,000 parts per million (ppm) is considered generally safe. Some legal cannabis states, however, have enacted stricter cutoff residual solvent levels based on recommendations from the Occupational Safety and Health Administration (OSHA) and the National Institute for Occupational Safety and Health (NIOSH). Residual cutoff levels vary by state.
While ethanol extraction may not be any more dangerous to use than light hydrocarbon extraction or CO2 extraction, the building requirements for ethanol extraction are less stringent than hydrocarbon extraction approval. Jurisdictions are familiar with approving distilleries that use ethanol compared to approving propane and butane facilities that elicit negative images based on a lingering stigma from black market extractions.
On top of receiving quicker approval by local governments, storage limits for ethanol are much more lenient compared to other solvents. That means an extraction facility can store more ethanol in the facility and use large volumes of ethanol at one time for cannabis or hemp extraction. Storing large volumes of solvent can keep the continuous extraction going without missing a beat.
Ethanol extraction systems are the go-to solution for large-scale commercial operations that process a high volume of cannabis or hemp. Ethanol is fast, reliable, and efficient at extracting low to mid-quality oils from cannabis and hemp for companies looking to scale. With the proper ethanol extraction system, cannabis companies can process hundreds of pounds of material per hour and gain a competitive edge.
Cut Labor Costs
Automated controls eliminate weeks or months of apprenticeship training required for manually controlled hydrocarbon systems.
Eliminate Operator Error
Pre-programmed recipe-monitoring system checks pressures and temperatures hundreds of times per second to remove risk of operator error.
Process 18 pounds of dried plant material or 25 pounds of fresh-frozen material per run. Single operator can process 400 pounds of biomass in a single day.

How to Make a Cannabis Tincture: Easy Cold Alcohol Extraction
Come learn how to make your own homemade cannabis tincture using a simple cold alcohol (ethanol) extraction method with our step-by-step guide. I’ve included plenty of photos to make the process as clear and easy to follow as possible. There is also a printable summary at the end – though I don’t think you’ll want to miss the extra tips in the body of the post.
Tinctures are a convenient, discreet, and easy way to enjoy your plant medicine. It’s kinder to your lungs than smoking or vaporizing, and offers more controlled and consistent dosing compared to smoking or homemade edibles. (I love that I can take just a few drops if needed.) You can use this homemade cannabis tincture recipe with any of your favorite cannabis strains, with CBD hemp only, or like we do – with homegrown herb!
What is a cannabis tincture?
A cannabis tincture is a concentrated alcohol-based cannabis extract, often referred to as “Green Dragon” among the cannabis community. High percentage alcohol is used as a solvent to extract the medicinal compounds (cannabinoids and terpenes) from the plant flower or “buds”. Though tinctures are essentially cannabis-infused alcohol, you do not get drunk since only a tiny amount is consumed.
Cannabis tinctures are highly therapeutic. Studies show that cannabis can be used to soothe a wide variety of physical and mental ailments, including sleep disorders, stress, anxiety, ADD/ADHD, muscle tension, joint pain, migraine headaches, inflammation, seizures, cancer, chronic pain and more. Cannabis tinctures can contain THC only (such as THC isolate), a blend of THC and CBD, or CBD alone.
When it comes to CBD, I always use my favorite certified organic full-spectrum CBD oil from NuVita. It’s federally-legal and is the most effective, potent and pure CBD oil I’ve ever tried. It does wonders for my anxiety, TMJ, and sleep issues! (Use code “deannacat” or this link to save 10% off) But if we want something with THC, we make our own tinctures using homegrown cannabis. It’s fun, rewarding, and a great way to save money!
What type of alcohol to make homemade cannabis tincture?
It is best to use either 200-proof food grade ethanol (aka ethyl alcohol) or 190-proof Everclear alcohol for this cannabis tincture recipe. Both are strong natural solvents that will effectively strip and separate the desired cannabinoids from the plant material. We use USDA organic ethanol from Culinary Solvents. It is pure food-grade grain alcohol, and doesn’t contain any additives or water. Use code “deannacat” to save 10% off pints, quarts, and gallons of regular and organic ethanol from Culinary Solvents!
Lower-proof alcohol (e.g. 80 proof vodka) is a weaker solvent and also has a higher water content than ethanol, which can interfere with the extraction and tincture-making process. You technically can make homemade cannabis tincture with vodka or other lower proof liquor, but it requires additional steps that we aren’t going to cover in this article.
Do not use rubbing alcohol.
What type of cannabis should I use?
It’s important to use decarbed cannabis in this homemade cannabis tincture recipe. If you’re not familiar with decarboxylation, it’s essentially the process of heating cannabis to “activate” it (explained more below). When exposed to heat, raw forms of THCA, CBDA, and other cannabinoids are converted to their active forms of THC and CBD – making it psychoactive as well as more therapeutic. (It’s the same reaction that occurs when you heat cannabis via smoking or vaporizing, and why eating raw bud doesn’t get you high).
Aside from that, use whatever cannabis you prefer or have on hand! Choose a strain (or combination of a couple) with traits you personally desire from your homemade cannabis tincture. We use what we grow: well-rounded sativa/indica hybrids that also offer a good amount of CBD. Learn how to grow your own organic cannabis at home here, and shop for seeds here.
For the most therapeutic tincture, I recommend using strains with a well-balanced THC to CBD ratio. If you’re looking for daytime relief with less mental effects, choose a CBD-dominant strain. Yes, you can totally use this cannabis tincture recipe with CBD hemp alone!
Why freeze alcohol and cannabis for extraction?
This homemade cannabis tincture recipe uses a cold ethanol extraction method, also referred to as quick wash ethanol extraction or “QWET”. Freezing the cannabis makes the trichomes detach from the plant material more efficiently. When mixed with cold ethanol, the desirable cannabinoids and terpenes readily extract and combine with the alcohol – resulting in a stronger, better tincture.
Furthermore, keeping the mixture at a very low temperature helps reduce the amount of undesirable compounds in your tincture, such as lipids and chlorophyll. It’s a chemistry thing, but basically the freezing temperature influences the polarity of the lipids and chlorophyll so they’re more likely to stay bound to the plant material (and therefore get filtered out) rather than combining with the ethanol.
When done right, the resulting filtered tincture wash will be clear and golden in color rather than cloudy or green.
Supplies Needed to Make a Homemade Cannabis Tincture
- 8 grams of decarbed cannabis
- 6 ounces of 200-proof food grade ethyl alcohol (ethanol) or 190 proof Everclear
- Freezer-safe glass containers, such as wide-mouth pint mason jars or half-pint jars with lids.
- Small unbleached coffee filters, like these ones
- Dropper bottles to store your finished tincture. We like these 2-ounce amber bottles; the droppers have mL markers on them for accurate dosing.
Yields: 2 ounces of homemade cannabis tincture
Please note that this is a two-day process, though ingredients are just sitting in the freezer for 97% of that time.
Step 1: Decarb your cannabis
To decarb cannabis, start by tearing up the buds into fairly small pieces. Then spread it out evenly on a baking sheet. For THC-dominant strains, heat the cannabis in the oven at 250°F for 25 to 30 minutes. For high-CBD strains, bake it for 40 to 50 minutes at the same temperature. (It takes slightly longer for CBDA to convert to CBD than THCA to THC does.) If you’re using a well-balanced THC:CBD strain, meet in the middle at 30 to 35 minutes. See this article for a more in-depth look at decarbing cannabis.
Don’t want to stink up the house? Consider using an Ardent Nova device for an easy, nearly odor-free decarboxylation experience. We just got one recently and love it!
Note that your cannabis will decrease in weight slightly during the decarb process (as it gets more dry). So, start with a few extra grams so you’ll end up with the 8 grams needed for this cannabis tincture recipe. Or, bake plenty so you have enough leftover to make homemade cannabis oil or topical salve!
Step 2: Freeze Cannabis and Alcohol (separately)
Use a scale to weigh out 8 grams of decarbed cannabis. Add the cannabis to a freezer-safe glass container with a lid. We like to use a wide-mouth pint glass jar. (Even though it seems more than large enough, the extra room in the jar makes it easier to shake compared to a half-pint jar.) Next add 6 ounces of ethanol to a separate freezer-safe container. Do not mix the alcohol and cannabis yet. Put both containers in the freezer for at least 24 hours.
Step 3: Combine Cannabis and Alcohol (First Wash)
After the initial 24 hours (or longer) is up, remove the cannabis and alcohol from the freezer. Pour ONLY HALF of the cold alcohol (3 ounces) into the container of frozen cannabis. Add a lid and shake vigorously for 5 minutes. Wrap the jar in a kitchen towel if it’s too cold to comfortably hold.
This process extracts the cannabinoids and terpenes from the plant material, and is considered the “first wash”. We’ll do two rounds total.
Now return the cannabis-alcohol mixture as well as the separate remaining 3 ounces of plain alcohol to the freezer for an additional 2 hours.
Step 4: Shake and Strain
Once the two hours are up, it’s time for another shake – and then we strain! Remove the jar of mixed cannabis and alcohol from the freezer, and shake it again for an additional 5 minutes. (We don’t need the jar of plain alcohol at this time.)
Next we’re going to strain the tincture through two mediums: cheesecloth first to filter the larger plant material, and then a finer coffee filter to further remove unwanted lipids and other residue.
First set up the coffee filter straining station. We find it easiest to set a small coffee filter in the top of a separate clean pint glass jar, fold it over the rim of the jar, and then screw on a lid ring to hold it in place. The cannabis tincture takes a while to seep through the filter, so holding it by hand isn’t fun.
Next, put cheesecloth over the jar that contains the cannabis-alcohol mixture (we use the ring trick again) and slowly pour it through the cheesecloth and into the coffee filter jar. See the photos below.
Now return the jar of remaining cannabis to the freezer while the first wash liquid is straining through the coffee filter (about 10 minutes).
Step 5: Second Wash & Strain
Now it’s time for the second and final wash. This step helps extract any final remaining cannabinoids from the plant material into your homemade cannabis tincture.
Simply repeat steps 3 and 4. Add the remaining 3 ounces of cold plain alcohol to the cannabis jar, add a lid, shake vigorously for 5 minutes, and strain through the cheesecloth and coffee filter once again – pouring it into the same filter and jar as the first wash.
Step 6: Reduce
After all the liquid has strained through the coffee filter into the jar, it’s time to reduce it by about half the volume. Excess alcohol will easily evaporate off, and the result is a more concentrated and effective homemade cannabis texture.
Do this by simply allowing the jar to sit out at room temperature with the lid off for several hours. We place the jar in front of a fan to help expedite the process. Note the volume of liquid in the container when you start (use a rubber band around the jar, or a glass marking pen). Keep an eye on it! Once it reduces by half, add a lid to stop further evaporation – or go ahead and bottle your final homemade cannabis tincture.
Step 7: Bottle and Store
Once it’s reduced by half, transfer the strained cannabis extract to a final storage bottle – such as these amber glass dropper bottles. Amber bottles are ideal since they reduce light exposure, which degrades cannabinoids. Store the bottle in the refrigerator for the best long-lasting quality. Congratulations, you just made a homemade cannabis tincture! Keep reading for usage and dosing information.
How to Use or Take a Cannabis Tincture
You can consume your cannabis tincture either under your tongue (sublingually) or mixed with a beverage (oral ingestion). Sublingual consumption will result in more immediate effects, while oral ingestion will have a slower onset but longer-lasting results. See the graphic below.
However, proceed with some caution! 200 proof ethanol is very strong, and I find it causes a burning sensation when applied straight under my tongue. To avoid that, I put a very small amount of water in my mouth first, squirt in the tincture, hold the diluted mixture in my mouth for a few minutes, and then swallow. Therefore my intake is mostly sublingual, but with a little oral ingestion too.
Strength and Dosing for Homemade Cannabis Tincture
When first trying your tincture, I suggest to start low and go slow. Without lab testing, it’s difficult to say exactly how potent a homemade cannabis tincture is. There are simply too many factors: the initial cannabinoid concentration and strain you used, how long and hot you decarbed it, the efficacy of your ethanol extraction process, and how much it was reduced at the end.
Start with a few drops, and then gradually increase the amount to find your “sweet spot” and desired results. (But wait a couple hours to see how you feel before taking more.) With this recipe, a quarter dropper is a fairly conservative starting point. I personally like to take .25 mL or a quarter dropper (though I’ve taken more just fine) while Aaron prefers about .5 mL or half a dropper. That’s just enough to take the edge off, relax our muscles, and help us sleep better without being too stony.
That was fairly simple, right?

Keyword: cannabis tincture alcohol, ethanol extraction cannabis tincture, green dragon recipe, homemade cannabis tincture, how to make cannabis tincture
- 8 grams decarbed cannabis
- 6 ounces 200-proof food grade eylth alcohol (ethanol) or 190-proof Everclear alcohol
Decarb your raw cannabis. Tear it up into fairly small pieces and spread on a baking sheet. For THC-dominant strains, heat the cannabis in the oven at 250°F for 25 to 30 minutes. For high-CBD strains, bake for 40 to 50 minutes and 30 to 35 minutes for a well-balanced THC:CBD strain. (I suggest starting with a few more than 8 grams since it will get lighter as it dries.)
Add 8 grams of decarbed cannabis to a freezer-safe glass container with a lid, and 6 ounces of ethanol to a separate freezer-safe container. Put both containers in the freezer for at least 24 hours.
First Wash: After the initial 24 hours (or longer), remove the cannabis and alcohol from the freezer. Pour only HALF of the cold alcohol (3 ounces) into the container of frozen cannabis. Add a lid and shake vigorously for 5 minutes. Now return the cannabis-alcohol mixture as well as the separate remaining 3 ounces of plain alcohol to the freezer for an additional 2 hours.
After two hours, remove the jar of mixed cannabis and alcohol from the freezer and shake it again for an additional 5 minutes. Then strain the mixture twice: first through a cheesecloth and then through a coffee filter into a separate clean container (as shown in this article). Return the jar of remaining cannabis to the freezer while the liquid is straining through the coffee filter (about 10 minutes).
Second Wash: Repeat steps 3 and 4. Add the remaining 3 ounces of cold plain alcohol to the cannabis jar, add a lid, shake vigorously for 5 minutes, and strain through the cheesecloth and coffee filter once again – pouring it into the same filter and jar as the first wash.
Reduce the liquid by half via evaporation. Simply set the jar out at room temperature with the lid off for several hours, or place in front of a fan to expedite the process. Note the volume of liquid in the container when you start. Once it reduces by half, add a lid to stop further evaporation – and/or transfer your finished tincture into it’s final storage bottle.
Store your homemade cannabis tincture in an opaque glass bottle in the refrigerator. We recommend 2-ounce amber dropper bottles.
Consume the tincture either under your tongue (sublingually) or mixed with a beverage (oral ingestion). Sublingual consumption will result in more immediate effects, while oral ingestion will have a slower onset but longer-lasting effects. **Please see notes of caution and additional information on usage/dosing below.
