I smoke cannabis daily and MD.

I am not trying to reduce my cannabis intake, no interest in quitting, but I am seeing that MD reduces my drive to smoke and I smoke less frequently and less of it when I do.

What I've learned here recently is that I probably want to reduce my MD a little bit because I smoke. I have noticed that smoking on MD days does seem to potentiate the effects, and so I think I can get away with reducing my MD from 150-170mg (my range based on unpowdered shrooms which are not always easy to break up to exactly 150mg) down to ~100mg.

I also take lion's mane, and I notice that lion's mane by itself seems to also reduce my drive to smoke somewhat.

I can't speak on the mental health advice side of things, though.
