Oh my God, did you see the stoner greeting cards?!!! That so pissed me off!! I have never been able to find any proof of Marijuana being the only "drug" in someones system in relation to a fatal car accident!!! The only statistics I have found specify ALCOHOL as the leading factor, and in some cases Marijuana was found in the drivers blood test. The pot could have been smoked days or even weeks before! (depending on your system, everyone metabolizes it differently) That is a bullshit and very misinformed site, they should do some research and find out the real facts!!!
