How long does THC remain in your system?

Yep someguy's right about 30 days and don't believe all those folk remedies, won't shift it, but lots of ways someone can substitute another's urine in the test.
But if he's serious about a profession that has zero tolerance then he should think about giving up altogether.
Any way that he can postpone the test till he's sure he's clean?Hey Tiffany sorry to burst your bubble but most of the troops in Vietnam were shitfaced not that I blame them wouldn't like to do active service myself

thc leaves a residue in the blood stream for a period of 30 days.

I really doubt it. MJ usually stays in your system 45 days.

How dare you ask this question! I don't want the people protecting our country to be some pot head trying to pass a drug test. Tell him to be a stand up guy an a model American then go into the military!

He should I am 6'4 165 take drug screens monthly. I can smoke Monday and pass it Friday. Done it!!! THC is stored in the fat tissue. The more fat the longer it stays up to 30 days. Trust me been doing this for years!!! If worse comes to worse drink water till urine is clear then pop 3-4 B-12 vitamins that puts the color back in your urine!!!!

Don't listen to these idiots. For chronic users like myself, smoking more than once on a daily basis, It will stay in the system for no more than 30 days. For your cousin, it is likely that he will pass his drug test. I would not recommend cutting it that close though. I use to take drug tests monthly. I would smoke for a week and give my system no less than two weeks to clear. He may pass but again it is risky. I would advise drinking a lot of water, dilluting his urine sample and having an extended time.

No, he won't, not even he won't be admitted to the military, if he is found out to be on drugs, he will be in prison or police custody.

No way. Is he going to MEPs? You could try a home piss test you can buy at CVS. But they do a blood test.

we don't need stoners defending the US he's gonna flunk the test, does he know that in some states now when illegal drugs show up in a piss or blood test that they can be ticketed for possession , reasoning being you had to have possessed it to use it. Tell him to quit smokin the dope that's why they call it dope ya dope!
