I’m glad this came out. It’s easy to forget that weed causes harm. Just from my own experience, when I’m on it I can’t think straight, can’t track a sentence from beginning to end. I can’t imagine where I’d be if those effects had applied long term as my brain was developing. Actually I can imagine. I’d be incapable of doing the high-paid, satisfying work I do now. I’d be stuck doing toilsome work with nowhere to go and a feeling that there’s more but I can’t quite grasp it.
I sometimes I have a feeling this is the case, as a regular user. But to clarify, I'm struggling with understanding differential geometry, and work as an se. Not trying to humblebrag but just trying to establish context. Should I be worried? I ask because I experience some of the same symptoms you do.
