If you only smoked weed one time it should clear up 3-7 days. THC is a potent drug so keep that in mind if you continue to smoke weed.
I never did before nor in future cause like a addiction should keep a distance from it us...
That all depends if it's urine, blood or hair follicle test.
I smoke one time but I taking a drug test two day after is it possible to have it in my system. If so what can I say are can I protest it.
Consider it to be a week on safe side. Drink lots of water. You can take Niason which can be found in the vitamin aisle at Wal-Mart or any major retailer
