if i passed a home drug test does that mean ill pass the lab test as well? THC is the drug.?

Home test kit tested negative, i went to a lab to get tested right after. Should i be worried?

Well if you didn't do anything to get the THC out of your system then you have a lot to be worried about. Just because a cheap home test didn't show it doesn't mean that a professional lab won't find it
lab test can detect up to 2 weeks longer than a homekit. good luck. if your skinny, have a high metabolism, work out, and drink a lot of fluid you will probably pass it as of today.
Did you use detox? Cause that's gonna make a whole lot of difference. It also depends on how long before you smoked, and how many times you smoke on a regular basis. THC stays in your system(without detox) for about 1-6 days(single use only), 3-9 days(weekly use), or 7-30 days(daily use). But unless you smoked before you went into the lab, you should be ok.
