Drug metabolites are little nasty things – they can stay with you a long time after you used last time. And when sometimes it is hard to determine the exact number of days one needs to stay clean to pass a drug test, it is also an issue in determining whether it is the frequency of usage or the actual amounts of how much was used play a more important role in getting your body clean.

- Hi, I got a question for you – I just found out that I failed my test, and I wanted to see if you can help me to understand why. I used to be an every day smoker, I mean – I smoked for over ten years, and then I stopped. So I have been clean for five years now, did not smoke at all, and then last week I was at my high school reunion and they were passing around the bowl and I had some. Just a little bit, but it was enough to get me feeling good, you know what I mean? So of course I had a random drug test at my work next week, and I just found that I failed it. How is that possible? It was only one time use, and I have been clean for so long! I am at a loss here; I do not understand how this could happen.

Unfortunately, pot can fool you this way – even from one time use it can be detected for quite some time. Do not hope that you know how you will test – get your hands on a self-tester and know for yourself. Also, to avoid even the slightest possibility of failing, consider protecting your privacy with the help of a detox product.
