YEAH!
it happened to me on the first day of schooll last year ....i was smoking this really sick cone splif that this canadian exchange student rolled with his 'canadian bud' but that shit got me so fucked up i couldnt move, my head was pounding with the sound of my heart beating and my lungs expanding and contracting. my vision then started to go a bit and it was getting harder to breath half cause of drymouth..... anyway i had to stan up and breath for a good cupple seconds and i still couldnt walk for a while later...we found out that his shit was good dro soaked in some sot of amonia or something fucked up like that
i've never had another incident like that since or before but my friend said that something simmilar happened to her when she smoked chronic which in her case was pot with coke sprinkeled on top.
moral of the story...
uhhhh....
smoke weed
