So California assemblyman John Benoit announced legislation today that would set up numerical limits for the amount of illegal drugs (I believe schedule 1 substances excluding marijuana¹) one could have in your blood stream and legally drive similar to the .08 BAC limit for alcohol. Apparently the lack of such specific limits is making it difficult to prosecute inebriated drivers (presumably because they must convince the jury of they reached some subjective level of impairment). This is a good reasonable idea that would likely save lives

But of course a proposal as sane and reasonable as this was too good to be true. Benoit has now said (same article) that he is seriously considering making this a zero tolerance law. Yup, that’s right apparently demonstrating our moral outrage that people are taking illicit substances is more important than saving lives on our highways.

As we all know from drug testing in athletes drugs can be detected in your bloodstream long after the individual in question has sobered up. Thus if you are a drug user the net effect of such a zero tolerance law would be to decrease the relative penalty for driving while inebriated. If you know that even if you wait till the next morning to drive the police could still throw you in jail because of the residual drugs in your bloodstream then why bother waiting? We’ve already (unreasonably in my opinion) expressed our moral disapproval of drugs by making them illegal but it’s criminally stupid to put our moral outrage over people’s lives. Not to mention the perfectly sober people who partied the night before who will end up in jail under such a program.

Of course if groups like Mother’s Against Drunk Driving are really about saving lives and improving highway safety I expect them to come out strongly against bills like this one. I On the other hand if they are about revenge and getting even with that type of person they will probably support this kind of zero-tolerance legislation. I’ll leave it to the reader to decide which is more likely.
