A new study published by the American Journal of Addiction, and funded in part by the National Institute of Health has found that THC – one of the primary components of cannabis – is “significantly associated with shorter sleep latency”, as well as “less difficulty falling asleep”.
For the study, “Thirteen male chronic daily cannabis smokers were administered oral THC doses (20 mg) around-the-clock for 7 days (40–120 mg daily) starting the afternoon after admission.”
Every morning, a questionnaire was completed by the participants, and “Plasma THC and 11-OH-THC (active metabolite) concentrations were measured in venous blood samples collected every evening. Changes in sleep characteristics over time and associations between sleep characteristics and plasma cannabinoid concentrations were evaluated with repeated measures mixed linear regression.”
Using this method, researches conclude; “Higher evening THC and 11-OH-THC concentrations were significantly associated with shorter sleep latency, less difficulty falling asleep, and more daytime sleep the following day.”
For anyone who has ever consumed cannabis, these results are certainly less than surprising. Still, being a government-funded study which indicates that cannabis can help with conditions such as insomnia, and even just standard sleep-troubles, it still holds some significance in validating cannabis as a medicine.
