How is crack used?
A.) The same way that freebase is used, namely, by placing the substance in a glass pipe (or hash pipe) with a fine mesh screen under it, then heating it and inhaling the vapours. The vapours of the crack are absorbed through the lungs, into the bloodstream, and transported to the brain within 10-15 seconds. One inhalation will produce a degree of intoxication usually lasting 10-15 minutes.
