How long does THC (marijuana) stay in your body after you smoke ONCE?

Question

this last weekend i smoked some weed 3 times with my friends. after its all said and done i probably took a total of ten pretty big rips off of this two foot bong. this is the only time i have ever smoked marijuana and would like to know how long it may stay in my system.

i also intend to drink allot of water for the next week or so to help flush it out.

i don't have a drug test coming up or anything but i am just paranoid and at my work they can give you a drug test without warning and you have to take it within three days.

Answer 1

From a single, first time dose, for most people, THC is detectable in the urine for less than seven days. It varies from as little as one or two, to a little higher than seven depending on how much you weigh (in terms of body fat), how fast your body's metabolism goes, how much fat you burn, calories you take in, and a host of other factors, but just about everyone you will ever meet will clear a single first time dose of THC out within seven days.

If you start using it regularly, it's a different story. And the above only applies to the standard 'dip stick' or chemical urine test. GC/MS tests can find it over a much larger window, but in the work place, GC/MS is only used to confirm a positive chemical test, due to it's high cost.

Answer 2

Your individual metabolism has a significant effect on how long the drug is present. If you have a high metabolism you will remove the drug faster. (Body weight is a good indicator of how high your metabolism is. If it seems like you can eat and eat and never gain any weight your metabolism is probably very good.)

For you, since you have only smoked once, you'll probably have it in your system up to 10 days. However, if you drink a lot of water like you plan to, you can decrease this time frame.

Answer 3

I hope your job gives you a drug test. It'll teach you a lesson; DONT DO ILLEGAL DRUGS!

Answer 4

I believe THC stays in your system for approx 4 weeks (28 days) and it doesn't really matter how much water you drink.
