If you licked a body part and tasted cocaine will it show up on a drug test?

It depends on how much you licked. If you were licking someones skin for 20 minutes I'm sure it might show up. But if you just took the smallest lick it might not. Cocaine will only stay in your system for 4 -8 days, so if the drug test is anytime after that you're fine. Unless they take a sample of your hair. Then you're screwed.
