I have been partaking in cannabis use throughout my life an have to often been met with cotton mouth. Cotton mouth for those who don't know a reduction of saliva production in relation to marijuana. Marijuana has been know to cause dryness in eyes and the mouth. I didn't make the connection between cannabis and my reduced sweating until I reached university. Within minutes of smoking marijuana the sweating stops, depending on the amount I consume I can be dry from 30 minutes to 5+ hours. Now with this realization I wanted to research and understand what causes this and if there was any concrete evidence to support it.
I've struggled with over sweating specifically in the armpits and tried a number of deodorants and antiperspirants and they don't make it past 10 minutes of wear. my sweating has only seemed to increase from 16 until now at the age of 20. When I first headed to the web for answers I was under whelmed to say the least. Hyperhidrosis doesn't have any simple solution and primary hyperhidrosis doesn't even have a known cause.
What I found mirrored what my doctor told me about marijuana. There is very little research on medical marijuana especially in relation to hyperhidrosis. the only information I found connecting marijuana and hyperhidrosis were on reddit, so here I am. In understanding marijuana the most important cannabinoids to focus on are THC and CBD. THC is the compound that allows you to get high when smoked , but CBD provides no psychoactive properties. Since i'm looking for a practical solution to my sweating where I'm not impaired 24/7 I tried to research specifically CDB and sweating. I know that for me marijuana will stop sweating but the ultimate question is does the THC or the CBD produce this affect? I found that THC is what causes cotton mouth as it effects the saliva, and have seen women in menopause use CBD to reduce hot flashes. Even with these findings I'm not sure what in marijuana causes reduction in sweating as there were no scientific studies or facts presented. Since I cannot find concrete evidence online i'm on route to test it myself. CBD oil can be added to water, but there is also new CBD Juul pods available now so that's the resource I will try first. Mainly my purpose in writing this is to get input from others and develop a conversation about hyperhidrosis and cannabis. I have hopes that one day there will be marijuana infused deodorants and soaps that reduce this sweating and provide an alternative to the side effects and surgeries.
Methods: Urine, hair, and sweat samples were simultaneously collected from 12 patients who were involved, respectively, in forensic case and monitoring abuse. Selectivity, linearity, limit of detection (LOD), limit of quantification (LOQ), recovery, intraday and interday imprecision, and inaccuracy of the quantification procedure were validated. LODs in hair were 0.05 ng/mg for Δ9-tetrahydrocannabinol, CBN, and CBD, and 0.005 ng/mg for 11-nor-Δ9-tetrahydrocannabinol-9-carboxylic acid. The LOD for sweat was 0.30 ng/patch for all substances. The LOQ in hair was 0.1 ng/mg for Δ9-tetrahydrocannabinol, CBN, and CBD, and 0.01 ng/mg for 11-nor-Δ9-tetrahydrocannabinol-9-carboxylic acid. The LOQ was 0.4 ng/patch in sweat for each analyte. Cannabinoid in urine was determined by means of immunochemical screening (cutoff 11-nor-Δ-tetrahydrocannabinol-9-carboxylic acid 50 ng/mL).
Background: Sweat testing, an alternative matrix for establishing drug abuse, offers additional benefits to the more common biological samples. The authors developed a procedure using gas chromatography-mass spectrometry to test for Δ9-tetrahydrocannabinol, 11-nor-Δ9-tetrahydrocannabinol-9-carboxylic acid, cannabinol (CBN), and cannabidiol (CBD) in a sweat patch. The results were compared with urine and hair sample results.
Results: All subjects tested positive for 11-nor-Δ9-tetrahydrocannabinol-9-carboxylic acid and Δ9-tetrahydrocannabinol in urine and hair. In sweat samples, Δ9-tetrahydrocannabinol was found in all patches (0.4-2.0 ng/patch); 6 cases were positive for CBN (0.4-0.5 ng/patch) and 3 for CBD (0.4-0.6 ng/patch); 11-nor-Δ9-tetrahydrocannabinol-9-carboxylic acid was never detected in patches.
Conclusions: Present sweat analysis results integrated the information from hair and urine and showed that sweat analysis is a suitable, noninvasive method for monitoring compliance with rehabilitation therapy and for detecting recent cumulative use of cannabinoids.
