If i smoke once, how long will it stay in my system?

Depends on how much you smoked! But normally takes 48 hours to get out of your system to pass a test. Drink pickle juice if you can hack it! Only way to get it out of your system...good luck!

it will stay in your system for at least 3 weeks. If you really need to pass the drug test & your willing to do anything, drink vinegar! it's the same thing as drinking pickle juice but it will do the job much quicker. Also obviously drink as much water as possible. Pee as often as you have to! & last but not least, try taking Niacin. It's a pill that will help flush your system. I buy mine from the GNC store at the mall. Silver bottle 500g 100pills $8. Best to take 3-4 a day spaced out 3-4 hours each. The pills will make you get extremely hot. you may feel like your burning up but ate last you know there working. DO NOT take them & go in front of anyone that you would not like to ask you questions. it is noticeable & your skin will stay red & burning for at least a half hour. sounds crazy but it really does work & it's worth it.

go get some pills called "AZO" there sold at walmart, drink alot of water & sweat and you should be okay. I smoke alot myself & i have to take a drug test every month and this method has proven itself over and over again. Take the "AZO" with some water, go work out & you should be okay. just remember to drink alot of water & use the restroom alot. I passed a drug test for Target after less 24 hours of smoking.. There are also Detox drinks that work real good for short notice drug test. good luck

im assuming you are talking about pot. It will stay in your system for 30 days, and you will more than likely NOT pass a drug test the next day. I'd suggest you graba detox kit from a head shop & start chuggin the water.

depends on what you smoke, cigs then you will pass, weed then your beat
