If law enforcement were really concerned about the effects of medical marijuana on traffic they would see that the data shows a nearly 9% decrease in traffic fatalities after enactment of medical marijuana laws, most due to a decrease in legal alcohol consumption.
Clearly, people who have their panties all in a bunch over the use of medical marijuana suffer from a lack of education to the facts. Despite the positive direction being made for Health Freedom in America, law makers are making it virtually impossible for a patient to drive or hold a job.
Not that I endorse getting stoned while operating any heavy machinery, the fact remains that any intoxicating effects of medical marijuana use wear off after as little as 30 to 60 minutes, yet the blood levels of THC remain. Common sense will show that if you use any medication on a regular basis, the indicators and chemical markers of that medicine will forever be detectable.
Comparatively alcohol and many prescriptive drugs have a much more debilitating and longer lasting intoxication effect than medical marijuana. Here’s the summary of national findings from the 2011 National Survey on Drug Use and Health, as well as another exhaustive report on Medical Marijuana Laws, Traffic Fatalities, and Alcohol Consumption: http://www.samhsa.gov/data/nsduh/2k11results/nsduhresults2011.pdf
