How come my drug test is positive if i dont do drugs?

i dont do drugs but, can my drug test come positive if my roommate do weed every day?

Well first of all, there are various foods and such that can cause you to test positive on drug tests. A good example is poppy seeds will cause you to read positive for opium. Another thing is, yes your room mate smoking weed will cause you to read positive for pot. It's second hand smoke, it's going into your system.

Also, there are some medicines both prescription and over the counter that have amphetamine in them that cause a positive for meth.

I have been in inpatient treatment and out patient treatment, you cannot test positive for weed. I've been to many classes on addiction and it is a proven fact that you cannot test positive for weed if your not smoking.

Positive for what could be medication.

I'm a drug and acohol testing tech and see this stuff every day. Honestly you wont be positive for thc unless your hotboxed and if they send it to the lab you will be positive for thc non the less, tests have a cut off of off 300ng/l of urine. My advice ask them to smoke else where if your trying to find a job.

my boyfriend just faied his drug test for pcp he never ever has done that and I think I would be able to tell if he ever did can anything make it a false test

Well Chi 87 I dont smoke weed at all and never have but my wife does and I failed for weed on a hair folicle test for Norfolk Southern so that is false. They have a cut off limit of 2ng and I got a letter saying I had 2.2ng so I didnt get the job. You absolutely can fail if your around second hand smoke.
