No, I don´t smoke weed. In our country it is forbidden, among other things. A familiar friend smoked weed regularly and could say he was already addicted. He was a young man, but his only worry was money and weed. I was sorry for him. Another friend smokes to this day and I have to tell him that he is familiar with it. I think it definitely affects his IQ. He's not stupid, but he's slow, unbalanced, and he does not care.
