ScienceDaily Summary:
A recent study looked at marijuana and alcohol use in people between the ages of 18 and 24. It’s probably not surprising that the results show a drastic increase in alcohol consumption in people just over 21; after all, that’s the minimum legal age to drink. What an economist-researcher found remarkable is that, at the same age, there was an equally dramatic drop in marijuana use.

ScienceDaily Summary:
Drivers who use alcohol and marijuana together weave more on a virtual roadway than drivers who use either substance independently, a new study has found. However, the cocktail of alcohol and marijuana does not double the effect of the impairment.

ScienceDaily Summary:
A new study finds that 28 percent of U.S. high school seniors have driven after using drugs or drinking alcohol in the past two weeks, or ridden in a vehicle with a driver who did. In particular, driving after smoking marijuana has increased over the past three years.  (“…the most recent three years have shown an increase in driving after using marijuana, which rose from 10 percent in 2008 to 12 percent in 2011.”)

Marijuana is becoming increasingly permitted in the US for medical and recreational use. A new study look at the relationship between alcohol and simultaneous versus concurrent marijuana use. Simultaneous users had double the odds of drunk driving, social consequences, and harms to self.

ScienceDaily Summary:

Teenagers who drink alcohol and smoke marijuana may be at increased risk for unsafe driving, according to a study. The findings point to a need for education on the risks of “simultaneous use” of alcohol and marijuana. The study of U.S. high school seniors found that teens who had used both in the past year had higher rates of traffic tickets/warnings and cat accidents. At particular risk were kids who used alcohol and marijuana at the same time: They were about 50 to 90 percent more likely to admit to unsafe driving than their peers who did not drink or smoke pot.
