Hey all, I am back after many months of successful employment. I was a very frequent visitor/poster about 6 months ago when I received a lucrative job offer only come to find out that I would be getting a Psychmedics hair test and, well, lets just say the Macuju method didnt pan out. After that fateful incident I have been totally clean without any relapses and I have been real proud. I have passed a urine test no sweat for a job since then. I just got another great new job and took the pre-employment urine test this morning..not worried about passing I know its all good. But here is my question:

This is a construction company and they are SUPER strict on testing. They sent me a 20 page manual about their drug policies and saying how I can expect to be tested twice every two years at random + any other random tests they want to do + for any on the job accidents. Thank god they do not do hair tests and it is only urine, blood, and saliva. In one of the pages they had a list of drugs and thresholds. For MJ the threshold for a positive result was 25ng/ml. Now I am trying to figure out what that equates to in smoking. I.e. can i smoke every weekend. only once a month, or what kind of frequency and level of smoking can i get away with without crossing the threshold. I know this is quite unknown territory but maybe if someone has any thoughts or any info would be awesome.
Thanks!
