My friend tried lsd for the first time about 2 and half weeks ago, the first experience opened his mind up to a whole different level (I've never done any Psychedelic Drugs) so he said and it seemed as if he was trying to grasp whatever he was opened up to for the next few days, than a 3 days later he dropped 1 tab for the second time and this one got him good, it's been two weeks now and he always seems different he is very paranoid randomly thinking that the world is going to end and he doesn't feel safe ever. When trying to talk to him he is always on a different page and claims to be able to know what i'm saying in my head. He is so distraught it's worrying his friends and even his family has noticed it now, real bad mood swings and such. He is a completely different person now and seems to have lost sanity no one knows where the old him is. I know sometimes the effects linger for a day or two after but after two weeks it's starting to worry me that we will never see the old him again, has anyone else seen a friend go through this from lsd will he ever be the same as he was? should we just give it more time and hope he is back to normal or what?
