Can confirm some asshole gave me a grams worth of a dab for my first dab, and I blacked out while standing up. Hit my head on the concrete. Luckily my ex's dad was a paramedic, and took care of me all night to make sure I wasn't going to die. When I was coherent enough, he ripped me a new one, and told me that if I ever have something like that again, go to the hospital because it might seem minor when in fact it could very well kill me.
