my parents test me once a week and i got caught with a very high THC level in my piss 97/100. I stayed clean for 2 weeks and got it down to 80/100. I smoked the past two days cause i coudlnt take it. My friend recommended two charcoal pills for two days before i test. and to get lots of exercise and water. i need to be under 80/100 for my test. what do i do? if i dont have my level lower than 80 im ****en screwed. HELP!
