A member asked:

Can you tell me if i had one puff of a cigarette, would the nicotine show in my blood test?

A doctor has provided 1 answer

Depends when test: I s done. If done within a few minutes or perhaps an hour of that puff, it might show up. If done many hours or days later, it should not. Most testing is done through urine rather than blood, because nicotine metabolites can be detected in higher amounts and for longer periods of time in urine.
