Inhaling a pre-roll is easy. Just: Remove the pre-roll from its packaging, Place the filter tip in your mouth, Light the other end, And inhale. It can take a few puffs to get a pre-roll going properly. If you want to put your pre-roll out and save it for later, crush the tip in an ashtray or on the ground. You can then replace the partially used pre-roll in its original packaging.
