Seeing as how states that legalized medical use saw a decline in traffic fatalities and injuries, and the fact that virtually no traffic fatalities and injuries have been attributed exclusively to marijuana use, this bill is a step in the right direction. But more needs to be done to force acknowledgement of the fact that the marijuana use simply is not even remotely a significant PRIMARY contributor to traffic violations, accidents, injuries, and/or fatalities.
This statement is consistent throughout all studies:
"In the introduction of its report, the Rocky Mountain HIDTA states that terms such as "marijuana-related" or "tested positive for marijuana" do "not necessarily prove that marijuana was the cause of the incident." The section on "Impaired Driving" also states that, when it comes to traffic fatalities, "marijuana-related" entails "any time marijuana shows up in the toxicology report [of drivers]. It could be marijuana only or marijuana with other drugs and/or alcohol.""
Since many in politics and ATF officials, and their corporate backers (primarily alcohol and tobacco manufacturers), have long held significant prejudices against marijuana and its users, the data is always bound up in epic struggles to provide and endorse truly unbiased studies and education.
I've read all of these and the same is true throughout: marijuana, when present, is very nearly always found alongside alcohol and other substances. And because marijuana lingers in a users system for months after even a single hefty bong toke it further complicates accurate data collection. This is why prohibition is so stupid: it makes it nearly impossible to collect genuinely accurate information on effects.
THERE does appear to be a difference between medical and recreational legalization and their effects. This likely is the result of people using it medicinally being familiar with the drug whereas those in recreationally approved states have significantly more first time users partaking:
Compare the above to the spin in more traditional media:
"There is no nationally accepted method for testing drivers, and the number of drugs to test for is large. Different drugs also have different effects on drivers. And there is no definitive data linking drugged driving to crashes."
Try as they might, reports like these reveal that marijuana is the bit player in traffic incidents:
