My friend and I shared 1 joint last night. She had eaten only a tuna sandwich, and I a salad. She had 2 lite beers and I 1 glass of red wine before we smoked. She fainted and had what looked like a seizure for about 5 seconds. About 10 minutes later, I felt dizzy and started sweating, but managed not to faint. Has this happened to anyone else? Any ideas or advice? I'm freaked out.
