Abstract
Cannabis intoxication adversely affects health, yet persistent effects following short-term abstinence in long-term cannabis users are unclear. This matched-subjects, cross-sectional study compared health outcomes of long-term cannabis and long-term tobacco-only users, relative to population norms. Highlights- We examined health outcomes of long-term cannabis users and long-term tobacco users.
- Cannabis users had poorer learning and memory than tobacco users.
- Cannabis users had slower reaction time on some tasks than tobacco users.
- Tobacco users reported poorer physical and mental health than cannabis users.
- Tobacco should be controlled in research investigating cannabis health outcomes.
