If you have a goal that needs to be met, like finishing or working on a track I don't suggest it. were working in numbers, analyzing outputs with subtlety and sometimes doing math! Weed is great for creativity, not for accomplishing goals. if your working on a bass only session, just warping sounds or creating a folder atmospheres using a granulator then maybe. but for a full track I think a pot of coffee would help more lol.
I don't smoke but I did a LOT years ago. maybe thats why I haven't taken music seriously until now. thats just my 2 cents.
