I don't know. I hear pot is detectable for 2 weeks or longer. That's never been my problem. However, I know that if you eat a poppyseed roll you'll test positive for opiates!

No

A good tester can see through that. Your temperature will be off from the inside of your body. Best way to pass a drug test is to not use any drugs or eat any poppyseed bagels. That will give you a positive test for opium because they are the same family.

Start drinking everything that will flush your body. Do this a lot and that should be enough. Don't sit in rooms where people are smoking pot that will enter your system and cause a positive test.

Drink lots of teas and soup. Take lots of vitamins.

my ex knows how... b vitamins and gallons of water. i am sure you could google that trick...

Try some Niacin and there is a OTC gallon of a drink which you use prior to a colonosaphy. If you can get that you will be on the toilet long enough to get you started.

Vit B , kelp pills and a ton of water start now and you might just do it

Don't do drugs, drugs are bad, mmmmkaaaaaaay. - Mr Mackey.

you can buy kits that purify your system

You can go to Smoke Shops also known as Head Shops and buy detoxifying kits. Don't know if they work or not. I know this. Cops hate those places because they seem to promote the use of illegal drugs and there's nothing illegal about the shops themselves.

I got in trouble once for calling a "water pipe" a bong repeatedly. Which it is but if a cop hears you say it the folks running the place can get in trouble. I just go to those places now cause they have the best incense. Okay, enough digressing. Hope all goes well. And pot should be legal. Alcohol is so much worse for a person.

Yes, the ol' Head Shoppe. You can shop in their but you can't call a bong a bong. Heck that was going on 20 years ago but if you want anything you can't call a duck a duck.

SImon, there's one not far from my neighborhood. It's in a strip center with a Starbucks where all the cops are known to hang out. It's kind of funny. But hey, I've got access to great incense nearby.

Is it called a Head Shoppe?

Smoke Shop. It's truly called that. Head shop I heard on a tv show once.

i dont need to say the best way to test neg is to not smoke pot. but my brother had to take a test to get a job. there is this stuff you can get that takes 24 hours to wash it out of your system. you pee blue during that time but it works. i dont know what it is called.

If you smoked only once a week will clean you out.
