Meta-meta-analysis
OR 1.2-1.4
Rogeberg & Elvik
Under a causal interpretation, this suggests that roughly 20–30% of traffic crashes involving cannabis use occur because of the cannabis use. By comparison, the comparable ‘average’ relative risk for accidents with fatalities after drinking alcohol has been estimated at 7.5, which would imply that approximately 85% of crashes involving alcohol occur because of alcohol.

And Dr. Romano said that lowering the legal blood-alcohol concentration, or B.A.C., to 0.05 or even 0.02 percent would reduce risk far more effectively than any effort to curb stoned driving.
“I’m not saying marijuana is safe,” he said. “But to me it’s clear that lowering the B.A.C. should be our top priority. That policy would save more lives.”http://www.nytimes.com/2014/02/18/health/driving-under-the-influence-of-mar...

Zopiclone
The effects of zopiclone 7.5 mg at 10 hours is comparable to the effects of a mean blood alcohol concentration between 0.5 and 0.8 mg/mL, which has been associated with a 2- to 3-fold increase in the risk of becoming involved in a traffic accident.
