Re: Fasting for detox of marijuana

I don't think you have anything to worry about. 4 weeks time should be plenty of time to eliminate the THC from your system.

I worked in an industry that tested at periodic physicals, and at any given moment without notice could make you give a urine sample for testing.

The keys to testing is what method they use, and how heavy a pot smoker you were. Not just how many days a week, but how much you smoked during those times. Even with the threat of being tested on the spot, I would smoke at the end of the week (Friday), and be clean by monday morning. The reason is that I could get off on one or two drags off what ever I was smoking from. Had I smoked a whole joint, or more this would have been impossible.

If they do hair analysis, they can detect drugs for quite some time. even to the point of telling how long ago you smoked by how far from the head the THC was in the hair shaft. Not sure about blood analysis. On a one time pre employment they might do blood analysis, but it would be too expensive to do with many employees on a regular basis.

Since you are fasting prior to the interview, and the fact that you quit 2 1/2 weeks ago I'm sure you have nothing to worry about.
