I have a hell of an experience to share. I work in a convenience store. 7 months ago, when i got the job, i passed the screen, but i was 3 weeks past my last smoking session. here i am now, being offered assistant manager, and i accepted. then the bomb came... i had to submit to another drug screen and another interview. i didn't know this before the offer was made. so i decided not to panic; perhaps the test wont take place for 2 weeks or more...red tape and all that. surprise!! it was in 4 days!! I was like 'there's no way i can pass this.!!'

So i got a otc detoxifier, but after taking it on the day of my test, i realized that it was only for detoxing the liver, kidney, and digestive tract. ugh! $30 wasted! but i water loaded (the only method that might pass you) and delayed the sample time of day to LATE (not morning pee, very heavy thc evidence) and went ahead with the test. Now, understand, it concerned me because the pre-employment drug test was after my interview. this was reversed in that i had to submit to a screen BEFORE the interview. So I'm already employed by this company, will a drug screen for a promotion get me fired?? Again, I decided not to panic because if i get fired, i can collect unemployment, and i'm one of their best workers, so it would make no sense to fire me. And the results are usually available wi/in 24 hrs, but it took them a whole week to tell me anything. That really unnerved me too. But if they found positive results within 24 hours, they would have had to fire me at that time if that was company policy. But they did not. As it turns out, a week after the test, I was told I had to go to my interview (meaning I passed the drug screen....how, i'll never know

Check the laws in your local area. This is what the internet is good for. It can tell you anything you need to know, if you're a good detective. According to the information I got, A company can only fire you if your test was the result of an accident on company premises and if you were tested at the time of the accident. It doesn't matter how long after the accident this occurred. If, as a result of the accident, you have a legal charge against you (that is, if there were police on the scene who arrested you for intox or posession) you must report it to the company. then the company can demand a screen and fire you if it's positive. At least that's how I understand it in my area of the country. There's a possibility in my case that they had no legal grounds to fire me for having thc in my pee, because of the circumstances. I may never know, as they never said "You passed the drug screen." and one should never ever ask. no news is good news. They probably decided that because i am in every way not fucked up by this drug and such a good employee, that firing me would not be a good idea, in that i probably had some proof that they did not follow procedure, and that they'd have to pay for me to sit on my ass collecting their unemployment payments for 6 months, so they'd rather have me working for them.
