It varies for different people. The average is 4-5 weeks. But I know a girl who swore she could to to the drug test high and pass. I myself passed a test after smoking the night before.

Hello ,
This will take 1 week to get out of his system , so I have been told

The thing is. The more fat you have on your body, the longer it stays in your body. This is because that's where it's stored, and thus why it takes so long to leave. I'd say do it about a month before you think you may get a drug test. If you know when you will get the test, pound the water before hand. Although this will NOT help wash it out of your body any faster, it will dilliute it so that when you get tested, there will be very little to no traces of thc in you. This is of course for a piss test. If they test you from your hair, well, you're basically screwed. Your best bet, honestly, if you're afraid of getting tested, is not to do it. I can see your circumstances though. Going to Amsterdam is a big chance to do it.

Personally, I wouldn't chance it. The chemicals can stay in the urine for up to 7 days and in the blood for over a month. My son, who has had honors classes at school, informed me that pot can be detected even longer after use by means of doing a test on the hair follicle. I don't know if that last is true, but it is something to think about.

If the test is hair rather than urine, a long time... or shave him head to toe for a few months after you get back, that might be weird, but if you went to Amsterdam it may not be too weird. One more thing, how the hell do you get 6 weeks off work! I had to go in this morning and it's a national holiday in the US...maybe you guys have too much free time to "burn"

the "on the spot" urine sample can be passed within 36 hours if the user is not habitual

Don't do it. If they give him the hair drug test he will fail unless he shaves his head.

Drink loads of water to flush out your system

If they do a hair test it can be 6 months until he is clear.

it can take up to 6 weeks for all the toxins to leave your body and for you to pass a drug test. Someone asked a simular question a few weeks ago , aparently there is something you can take to get the toxins out of your system quicker, with out looking either for the past question asked or looking for the answer over the internet i can't tell you what it is called

Its all in your matabolism.

The halflife of THC is between 0.8 to 9.8 days and it all depends on what kind of smoker you are. If you're a very occassional smoker with a fast matabolism, you'll be clean very quickly. A heavy user with slow matabolism will need to detox for awhile. Flushing your system with lots of liquid and B vitamins may help. If you're really unsure pop a few aspirin before going in, it may help bring up an inconclusive result. (These are "tips" that are not medically backed or proven or anything so take them for what they are).

Other than that, delay the test for as long as possible or get someone elses urine.

Honesty, if he doesn't smoke regularly and he only smokes once or twice in Amsterdam, he'll most likely be clean in 48 hours.

Its takes up to a month to be free from the toxins left in the skin from cannabis.
