Probably the silliest question ever but cant get it off my mind
So basically I struggle with both OCD and anxiety, and I went out last night and I am a non-smoker, but because literally all my friends smoke socially when clubbing they asked me to try it yes purely my decision, but I was drunk so I said why not I literally only had one puff and that was it and handed it back. But now I feel so guilty cause all I'm seeing in my mind are those pictures of lungs and stuff after smoking. Anyway my question is will I know have tobacco permanently in my lungs and/or will this affect me in any way? I understand that it's a bit of a stupid question but my paranoia won't let me get it off my mind.
