Abstract
Background
Low-THC cannabis products have become popular worldwide and are used as self-treatment for a variety of medical conditions despite limited high-quality evidence on efficacy or long-term side-effects.
Method: We compare the experiences of CBD-oil-only users to that of users, who indicated use of cannabis products conventionally higher in THC (high-THC cannabis) with respect to number of symptoms relieved, overall perceived effect on symptoms, effect on pain level and sleep duration, and perceived side-effects. A self-selected convenience sample of Danish cannabis users were recruited to an anonymous online survey. Inclusion criteria were 18 years or older and use of cannabis as medicine (CaM) (prescribed or non-prescribed).
Results
The final sample included 2.642 users of CaM, of which 992 were CBD-oil-only users and 1650 used high-THC products. Compared to respondents who used high-THC cannabis, CBD-oil-only users reported fewer symptoms relieved by cannabis, a slightly lower overall symptom reduction, as well as comparable pain reduction and sleep improvement. CBD-oil-only users reported fewer side-effects and were more likely to report no side-effects of cannabis.
Conclusion: CBD-oils may produce less intense effects compared to high-THC cannabis products, while also producing fewer side-effects. Regulation of the legal low-THC cannabis market is needed.
