Psychological effects are, in general, reversible. Also, they tend to be dose-dependent, and rather obvious. It's easy to avoid them by limiting consumption. I stopped smoking weed for other reasons, but I didn't really care if my memory formation was impaired after 9 PM. Effects on the heart, on the other hand, can build up for years without much warning, since most people don't get regular EKG.
