I'm slightly embarrassed that to be asking this because it is so unlike me and far from my morals and character. I was diagnosed with OCD in sixth grade last Saturday so about 8 days ago I smoked marijuana and I now can't stop thinking about how much I regret it and want it out of my body completely. I have been drinking detox tea and have gone to an infared sauna twice now I also took a laxative. How can I tell if it is out of my system?
