I'm a sixteen year old male with no mental health issues, I do get a tiny bit anxious around new people but I wouldn't say that's a major factor. I recently have had a lot of pressure and anxiety the past two, three weeks due to exams and trouble with friendships, relationships etc. I have smoked cannabis a couple of times before, feeling hardly any effects, maybe enhanced happiness but that's it. I smoked it again at the weekend, Saturday to be precise and had the worst experience of my life. The high started off as a tingly feeling, enhanced senses but then quickly deteriorated into my body feeling like it was burning inside and I had a (in my opinion) a severe panic attack. I literally thought I was going to die. The rest of that day, I calmed myself down with a movie and went to sleep, the following Sunday, I stayed at home and didn't feel any effect until night, where I was slightly anxious for no reason. Today is Monday and I went to school. I had a panic attack at school today, pretty minor stuff. Luckily I left the classroom before I had it as I was feeling really dizzy and had tunnel vision. I think I got anxious after my body started tingling again, afraid I was going to have another experience like I did on Saturday. At home, I switch between feeling really anxious to pretty relaxed. My body still tingles and get minor pains in a few places which for some reason (as much as I say to myself no) I think I'm going to have another attack. I am literally anxious about being anxious and I can't help it. My heart hasn't stopped beating significantly faster than usual since the morning. I'm worried the cannabis has had a big impact on my psychological health or is this me just being anxious again. I keep telling myself that once I purge my body of the THC, it'll be all good but then I think it'll last forever, it's all confusing. Don't give me a lesson on how bad drugs are etc. I won't be taking anything for a while after this experience. In conclusion, I tried cannabis, had a panic attack and is now scared it has had some long term effect on me. How long do you think it'll last? Anyone share their scientific input?
