I recently had oral sex with an individual that I later found out used meth. I just took a pre-employment drug test, and I am wondering, will I test positive on this? I did not swallow his semen. I did not make out with him, or exchange any other bodily fluids. I am worried about this because if I do test positive, I will not be able to hold another position within the airline industry for another five or 10 years. Please let me know!
