How long does it take for cocaine to exit your bloodstream?

Regardless of how it is ingested (smoked, injected, inhaled etc..) It is almost instantaneous however, you will feel the effects within a second or two when injected, within five to ten seconds when smoked and within a minute when inhaled (unless your nose is clogged. If that is the case it may never absorb and you will never feel the effects only the numbness.) Even though the result is achieved quickly, each different method has a very different result (high) and each has a result that sustains for a different length of time. You really don't need to know all of this. Just ummm say no.
