The key seems to be the activation of MCH during REM rather than REM itself.
I wonder if MCH plays a role in memory impairment caused by frequent cannabis usage. It is also related to appetite enhancement, and I saw at least one study saying cannabinoids stimulate MCH. [1]
The REM connection is especially interesting - because as many long-term cannabis users will tell you, you usually stop dreaming after a while of use. If you stop again though, dreams often come back with a vengeance. Studies say this is due to REM impairment and then REM rebound after stopping [2]. I'm totally spit-balling, but it makes me wonder if it's possible the REM changes long-term stoners experience could be from your body trying to regulate a overload of MCH.

- sysbin 7y agoInterestingly dreams return after shortly stopping cannabis but more fascinating is how the dreams that come back will be in nightmare form. I've experienced this outcome and I've seen it reported online by other users. Maybe anecdotal but I find it peculiarly odd of false because the outcome has happened several times.
- wolco 7y agoI would say more vivid but not necessarily nightmares
- ksaj 7y agoI've never heard of this. I've been using Cannabis for quite a long time (decades) and I still have dreams. Every night, even. As a child I used to have chronic nightmares. It is pretty rare these days. So if anything, this lack of dreams (and the return of mainly nightmares) either only affects some people, or it is simply a matter of not remembering the dreams. Or both.
