So I am writing this for my brother who now goes through a very hard time. He is 22 and he smoked pot like 10-20 times in his life, first time at the age of 16 or 17 and he never had a bad trip. I have the same history (I am 19 though). Anyway, we smoked together only 3 months ago at home. This time he acted really weird. The trips started off normally, but after about 30 minutes he kinda really lost control of his mind, although we didn't smoke much at all. Less than a gram actually. He started taking all kind of strange books from the bookcase (some cheap BS about religion and conspiracies, or some really good poetry). Anyway, he was really weird and he believed that he is some kind of genius and he dicovered the secret of the universe. After another 30 minutes his situation got worse. He was barely able to answer my simple questions as what is his name and he was very absent. He looked like he was thinking deeply about his theories. From time to time he made exlamation like ''evrika!'' but that's all he was saying. Anyway after like 3 hours the trip seemed to go and he fell asleep as it was late anyway. The next days he was about normal, but I was able to see some change in him. After some 3 weeks me and a friends smoked again and he was with us. He smoked too a very little bit only to prove himself that he is ok and the episode I have just described was only a bad trip. I did't think it was a good idea for him to smoke but I thought that he is my older brother and I can't tell him what to do. He didn't have this bad trip again, maybe because he simply smoked too little, but he seemed absent anyway.After that, meaning in the next month, he seemed more and more depressed. It was easy to see that as he was a very funny guy before. The last two weeks have been the worst. He didn't touch weed at all since when I was with that third guy, but he told me that he was anxious and he had weird nightmares and some kind of pannic attacks. Few days ago he had some kind of crisis. I thought it was a pannic attack (and maybe that's what it really was, I am not an expert at all). More precisely he woke up shortly after he fell asleep. He had a really scary nightmare again. Only this time he acted the same way he did when he smoked for the first time with me. He talked all night about conspiracies, about god, about death and so on. He was very scared, paranoid and confused. He believed that there are some gypsies outsied thrying to kill him. Than he said that they are actually going after our father who lives quite far away from our city. I talked to him all night long and finally I managed to calm him. He fell asleep in the morning and the next day he was sort of absent but I really thought he was going to be alright. The next night the same thing happened only a little scarrier. Again in the morning I managed to calm him. He was going to go on a trip with his girlfriend at the sea, at my dad's house, and he really didn't want to cancel that. As this time he really seemed okay, and as he was going to stay at my dad's,me and my mom (who was present at these last two night episodes) decide to let him go. He was normal all day, but at suset his anxiety and paranoia came back. He left a restaurant without paying and leaving his clothes there, saying that some black men are following him. That's because he saw some gypsies. He kept saying that they are going after dad, or after his girlfriend. Anyway, when he arrived at my dad's house, he tried to stragrle his girlfriend telling her that it it better for her as the gypsied were going to torture her. I don't know how, but he escaped,, but he could've killed her. He also broke a window and got cut quite bad. My father was home just in time to call an ambulance for both of them. The girl is alright now but he was held for one night at the local hospital which was a very bad one. The doctors there scared him. They boun him and gave him calmants. That happened last night. Today he came back home and he seemed again normal. I was actually happy as he seemed even better that the morning before he left. He even made some of the jokes he used to do before all this started. We gave him some medicine though, that a friend of my father's prestripted. Something to help him sleep. And he did fall asleep, but after an hour or two he had that nightmare again. My uncle was home, and along with my mother, we all tried to talk him out of his paranoia. He insisted to call father to warn him about black men that are coming after him. Long story short, now he is at a psychiatric hospitals, probably bound to a bed and filled with calmants. At least this is a good hospital, but still, that's not where I want my brother to be. I want to help him but I really don't know what to do. I am afraid that he has schizophrenia. Can anyone help me with some suggestions maybe? Have anyone ever seen something similar?Pleas help me and thank you for reading this.
