Question

If you are around people doing harmful substances, but you don't do it can it show up on a drug test?

Answer 1

You will probably come into contact with whatever they are doing, even if you never took any yourself.  Stay away from them.

Answer 2

First of all you don't need those friends.If you are in a car full of people  and all are smoking pot you naturally are going to inhale some of it.Drug tests have amounts over which they are considered positive.

Answer 3

Its very unlikely.

Unless you're inhaling a whole LOAD of smoke.

Wouldn't worry about it if I were you.

Answer 4

noo

Answer 5

It depends on the substance, the way of of exposure {by touch, inhalation, etc.}, and the time between the exposure and the test. For example, if you're inside a closed car where people are smoking weed and you inhale the smoke for several minutes, chances are that you'll give a positive result  for marijuana for up to 28 to 30 days after the exposure. If your skin happens to come in contact with cocaine or heroin {even if it's just a little residue in a straw or a cooker}, your skin will absorb the substance and you'll turn out positive within 48 to 72 hours for cocaine, and for up to 7 days for heroin. Disgracefully, an incident like this happened to me on August last year. My then-boyfriend was a heavy intranasal cocaine user; his apartment was littered with dozens of empty bags and used snorting straws. I did some cleaning at his place, and put the cocaine bags and used straws into a trash bag; it didn't occur to me that I should have worn gloves to do the cleaning. Two days later, I was required to provide a urine sample for drug testing {I'm into a Methadone maintenance program because I'd been an IV heroin addict, and they do surprise drug testing to all patients}. The test turned out positive for cocaine; I'd NEVER given a positive for cocaine {or for any other drug, with the exception of heroin during the first 5 weeks at the beginning of treatment} in my five years as a patient. I explained the situation to the Medical Director of the program; given my long history of consistent negative results to drug testing, she explained to me that I must have absorbed some cocaine residue through my skin and ordered the positive result to be removed from my records.
