My advice is to first, slap your friend smack across the face. Second, Keep on inhaling
Lol your friend is a dumbass, you need to inhale or you wont get as high becaue then you dont absorb as much thc, also coughing or choking is good because then it opens up some shit in ur lungs(dont remeber what im baked) but then you get more thc in you, meaning you get higher
