Couldn't agree more. I wonder what other drugs were in his system.Funny how they focus on how the guy had smoked pot, yet decided the "other drugs" needed no further elaboration. Since he was using medical marijuana I wonder if any of those other drugs happened to be common prescriptions. Someone who smoked pot right before getting in a vehicle is still considerably less likely to crash than someone who is well under the legal alcohol limit or using certain prescription medication. The same goes for most other illicit substances. Of course, since the pharmaceutical industry dominates the medical research field a study they fund may very well conclude otherwise. The same goes for any government study. However, it will just be the same old "correlation equals causation" arguments our fraudulent scientific establishment has used to shut down any positions they disagree with.
No need for a legal limit exists when it comes to most illicit substances. However, the notion that it does seriously impair someone's driving ability is used as one of many scare tactics to perpetuate the drug war. Another one is to focus on health effects, especially by making the link that marijuana when smoked has the same effects as tobacco (an ironic argument given the latter is legal). They focus on things produced when smoking it that cause cancer in tobacco smokers while excluding the proven cancer-fighting effect of THC. Studies actually looking at the health of users shoot down all the scary theories about its use.
Alcohol is the king of deadly substances yet is readily promoted with sports arenas even named after major brands. Yet apparently we are supposed to fear marijuana being legal.
