I'm assuming you mean "will THC show up on a urine test from a contact high?" (meaning you didn't actually smoke, you were buzzed by "second-smoke") to which the answer is NO. A contact high means you have less than 5% of the THC from the entire sesh in your system.
I used marijuana one time and only hit it once,how long will it stay in my urine?
30 days
About 15 days.
Almost immediately.;-)
45+ days
Marijuana is detectable in the urine for a month after consumption.
Usually Seven to ten days.
15 days tops.
I hadn't smoked for three months . I took two hits off a pipe and passed a urine test 13 days later .
Marijuana's active component takes up to a month to clear completely from your body.
Just so long as you don't pee on the marijuana :)
THC on average will have greater than 50ng/ml potency in your urine for up to 3 months.
