My Friend Just Passed Out And Woke Up. Help?!?

So, a friend who takes adderall just came over and had a glass of wine w/ dinner and smoked a few bowls w/ us. He then sat back slowly on the couch, put his head back and went white, eyes open, pupils dilated, mouth open, GHOST WHITE. I thought he was choking, because there was like no breath coming out of his mouth, so I tried CPR (or some awful attempt at it). He then slowly looked at us, and sat up. He is now really white still (color came back, then left like 15 min ago), feels nauseous and is just slumped over not feeling well at all. He said he felt dizzy before it hit, tingling in his brain, and saw it coming, but couldn't do or say anything. He said its happened once before, but not like that. What should we do for him? He doesn't want to go to the hospital, and what I've read on one other blog site says he shouldn't need to. But is there anything we can do to help him feel better? Ginger? Some Vitamin? He's drinking water and has a wet towel on his forehead. Help? o.O
