okay, i had an idea. you know when you said you were on the stairs and it went dark? tell your friend to turn the light back on. lol. for real though, i have trouble believing that you think this is something serious. if you really thought you were doing brain damage then why would you keep smoking? btw, nobody has ever even come close to figuing out the power of the human brain. ive had alot the same kind of things happen, get all weak feeling and turn pale and shit. when your high things freak you out more, you may have just let your mind run away with you in tow
