I'm really surprised no one has brought this up, so I'll give you my breakdown of the situation and the science and rationale behind my thinking. THC attaches itself in fat cells in your body. The less fat you have, the less amount of time THC will show up in your system. For example, my buddy, who was an athlete (a swimmer at that), had a drug test and had smoked 7 days before his test and he passed the drug test. Most people think that you need 30 days before THC is not detected in your system. This is not true. Besides using masking agents, which are tested for in most drug tests, the best way to rid yourself of THC is to work out and (forgive my language) go #2 as much as possible. I assume that Percy Harvin, being a potential first round NFL draft pick is a gymrat. I bet he spends 2-3 hours a day working out and if hes not working out, i guarantee you he's not on the sofa eatin potato chips all the time. Maybe he was... when he gettin stoned, but I will give him the benefit of the doubt that 99% of the time he is being active, in which case... your body is burning calories.. in which you will be burning the THC outta your body. On a personal note, I went to Amsterdam a while back and visited the coffeeshops and 2 weeks after I arrived back to america, low and behold, I was conveniently/randomly drug tested for something I did legally in another country. I tend to do alot of walking and I try to stay as active and play alot of sports so 14 days after I had last smoked, I did the drug test.. and guess what... my test came up negative. Conclusion... I personally think Percy Harvin was smoking bud less than a week before his drug test. Politically and Morally, we need to end the prohibition in regards to this plant. However, as a Titans Fan, this bothers me. Why? It bothers me because he hasnt even signed a contract and he blatently disregards the fact that an organization is going to take a chance on him, pay him millions, and he isn't even going to adhear to the rules. I mean seriously.. All he had to do is stop for a week. He could be an awesome player but I want guys who are dedicated and put the team first rather than guys that put themselves first. I know this is pothead blasphemy... but its true.
