How Long Does Weed Stay In Your System

How Long Does Weed Stay In Your Body? The answer is simple but you should look at some others saying:

Hi I’m a female, 18, I weigh 135 pounds and I’m 5’8. I smoke at most once a week and I smoked last night but only two big hits. I might be drug tested in two weeks so do you think I would be fine with some exercise (which I do regularly) and plenty of water?

Don’t take any of that detox shit im in the army and when i first joined my recurtier asked if i can pass a piss test and i said no and he gave me 30days i told him about detox stuff and he said the drug test now can tell if you took anything to cover it so don’t trust these assholes best way is to drink lots of water sweat and not smoke if you have a drug test but skinny ppl can get clean in as soon as a week my bro does it just by sweating and drinking lots of water also drink powder the day before the b12 in it adds color to your pee.

Just wondering where you guys disappeared to… noticed you haven’t replied to any blogs since October… anyway, curious if I have reason to be concerned.
I smoked 2 hits of a 3 year old bud from a metal hand pipe(previously smoked two years ago) probably pure resin at this point, 5-6 days ago.
I don’t ever smoke it anymore, its been 4-5 years and need to do urinalysis tomorrow am.
Work in a job that performs bending, pushing, pulling, squatting, walking 8 hours per day, 5 days a week so amply exercised and fit. Drink 7-8 cups water daily at the bare minimum plus 4-5 cups of coffee 12 oz.
