i smoked cigs for about 5 yrs, and weed for the same amount...ANY smoke you inhale is liable to make you cough...cuz smoke isn't really too good for you. BUT...my opinion is that if you're gonna smoke something, and any kinda smoke is bad for your lungs and your body and all that, then AT LEAST fuckin smoke something that is gonna DO something to you. i mean, yeah ppl need a nicotiene fix sometimes...but weed will actually get you high...so it serves an actual purpose.
