I've smoked weed from age 16 all the way to age 20. That's 4 important developmental years.
I'm pretty sure it fucked up my working memory, since I can't hold as many things in my brain at the same time, like I used to be able to.
Could someone that has already done the research on this topic, link me some studies on weed and its impact IQ/working memory? I just need to confirm if the damage is permanent or not
