I heard on the radio yesterday that a man received a DUI. But, this DUI was not given for drinking alcohol, instead for the smoking of marajuana. While driving, this man crashed into a mother with her three kids. All died except for one of the children. Initially the police officers concluded that the man was not under the influence after using the breathalizer. However, a month later the blood test showed that the man had THC, the main component in marajuana, in his system. Suprisingly to me, the man was charged with a DUI. This is the first case to use smoking weed as an outlet for issueing a DUI. This seems a bit nuts to me. First of all, marajuana stays in one's system for up to thirty days so how can they prove that this was the cause of the fatal crash. Also, the police officers at the scene saw no sign of impairment in the man. So how can they say a month later that because the man had THC in his system, he was at that particular moment too impared by weed to drive safely? This seems to be too much of an assumption.
