Problem with drug testing

I need some help and hopefully someone on here can help me. I am 6' tall and weigh around 400lbs, I was a heavy user of pot from the time I was 14 until just recently (now 22) when I was put on probation, I quit for 5 months with no problems then decided that I wanted to smoke. I got in trouble with probation and they sent me to outpatient drug treatment where I have been drug tested almost weekly for the past 4 weeks. The facility claims that their test levels go from 0-200 not sure what type of urine test it is but that is their claim, now when I was first tested on May 29 I was at the max (200) which I knew because I had smoked several times in the weeks leading up to it and had not tried to cover it up because they said that would get me in more trouble. Now here it is a month later and my last test came in and my levels are at 188 so they claim, now they had went down to 176 on June 8th and then up to 184 on June 12th and then my last test was June 22nd and the levels they claim are 188. Now I haven't used since May 28th but they are saying I am using and my probation officer is about to violate me. If anyone can help me with this problem I would appreciate it, or if you can point me in the right direction.

The problem is rhc levels can fluctuate from day to day, but they don't recognize that. And its worse for us that are heavy. Try changing to a high fiber diet with metamucil and try to get some sort of exercise. It will help. Then of your UA day read up on the dillution sticky and try that to get your levels down Use gatorade instead of the water and don't worry about the aspirin.
