There are various ways of consuming cannabis, though, the one that I experienced first, like most people then was smoking. There are obviously other ways that are more appropriate for different situations. There is nothing that is faster in terms of getting the desired results, whether it is simply for fun or medicinal effects than smoking in some form or other. The fastest way to do it, if you have the facilities is by vaping that you get the full effect almost instantly. Particularly, if someone is in pain or nauseous, having immediate pressing problems. By far the best way to do it is to inhale it rather than waiting particularly obviously over never ingesting.
