No offense, but that's crazy. I've failed a urine test 30 days after smoking. I'm only 5ft 11in and weigh 165. My BMI is extremely low, but I had to quit for almost 60 days to clear it out of my system.

The real truth is you can't tell how someone's body reacts to it. I'm in very good shape, but for some reason THC doesn't flush very quickly from me.
