well first of all if youre inhaling wrong it can be really harsh.my first time i coughed for five minutes straight. instead of trying to suck it down just kinda pull it in to your mouth then breathe some air in to push it down kinda like a shotgun. small hits help too build up. eventually you'll get it. im gonna take a guess and say youre new to weed. dont worry we all start somewhere. but if you want make a home made bong or bubbler/ waterpipe. i used a sobe bottle a few straws and a socket. get creative try some new things. when you get it down you wont cough alot until you reach what i call the breaking point. basically when i smoke up to the point im high then i take a rip and go into a coughing fit. but youll get that later.
peace
