With today's potent buds this is a good way to explode your lungs;) With a well rolled joint you can take small puffs, maybe learn how to let them out of your mouth and re-inhale through your nose, and avoid getting so much in your lungs that you have to release it in explosive coughs. Today's bud is so strong that just a couple of these are plenty, unless of course you are smoking too much and developing a high tolerance, probably not a good idea. Of course cigarette and cigar smokers have already compromised their lungs enough that they may not experience the too deep toke.)
