A member asked:

I haven't touched cocaine but i tested positive on a mouth swab test what other possibilities are there for that to happen?

False positive & $: You likely had a screening test and the results of a screening test needs to be confirmed with a more definitive test. Please note that dollar bills in the US are often contaminated with cocaine from people who use these to snort cocaine. If you got contaminated from such bills that could be an other explanation.
