Marijuana's hazy contribution to highway deaths

Public officials and safety advocates worry there will be more drivers high on pot and a big increase in traffic deaths as states liberalize marijuana laws.

It's not clear, though, whether those concerns are merited. Researchers are divided on the question.

Studies of marijuana's effects show the drug can slow decision-making, decrease and impede multitasking. But drivers high on pot tend to be aware that they are impaired and try to compensate by driving slowly, avoiding risky actions and allowing extra room between vehicles.

On the other hand, combining marijuana with alcohol appears to eliminate the pot smoker's exaggerated caution and to increase driving impairment beyond the effects of either substance alone.

It is illegal in all states to drive while impaired by marijuana.

My gosh people. OF COURSE people are going to drive while high!! And those of us who don't are going to be the ones who suffer by losing loved ones in crashes. But, those who want to legalize this stuff hide from this particular fact as long as they get their right to get high.

This is the 2nd article vilifying MJ that I've read today. It is starting to look like MedXpress has an axe to grind, a liberal axe. Alcohol has caused much more harm and deaths than MJ ever has or ever will.

And the effects on road rage? Surprising I'd bet- but someone should at least look at it honestly.
