If you take two hits of weed how long will it stay in ur system 5"8 180lbs

- : - if this is the first time you every smoked marijuana and you took two puffs, it will most likely show no metabolite in urine within a week. If you have been a heavy user, the metabolites could in appear in urine for months.

It depends: Strength of herb dilution of urine body fat sensitivity of test etc. All these variable can play a role.. That being said if not a regular user most likely will not be detected after a week..Possibly days.
