From Wikipedia I wonder if anyone is familiar with this. The reason why I became interested is because I started to look into the fact that different people metabolize medications at different rates - probably due to genetics. this might partly explain why different people react differently to specific medications and/or need different dosages. I believe that I might be a "fast oxidizer" and I base this conclusion on the fact that a few months ago, I had to detox from Klonopin - 3mg a day. I had a blood test taken the morning after I stopped taking it and it showed no level of Klonopin in my system. Whereas someone else in the same situation still had it show up 3 weeks later. I wonder how much of an effect a person's rate of medication metabolism has on the efficiency of the drug.
