I am getting a pre-employment drug test for a moving company for a summer job. I won't have to take it until may 17th. I weigh 175 lbs I am 5 feet 11 inches tall an average metabolism (not fast, not slow) I have smoke and vaped almost every day since January 20th (I had a month off from dec. 16 to jan. 20th or so, before I smoked everyday as well) I exercise 3-4 times a week (usually running, rowing, or weight lifting) The urine test (I believe it's a urine test) is done at a different location than the employer is. She said it is sent to some medical center to get the results and it takes 2 days. When should I stop smoking? I want to be able to get really high for 4/20. would it be recommended to take a detox kit before the test as well (especially since I know exactly when it is)?
