WOODBURY - With marijuana laws loosening in states across the country, anti-drunk driving advocates are concerned about a possible increase in fatalities involving intoxicated drivers.

Marge Lee, an anti-drunk driving advocate, says they have no choice but to wait and see if there is a direct correlation between drivers high on marijuana and the death rate. “The price is too high in my opinion,” Lee told News 12.

Joseph Beer, 19, pleaded guilty to aggravated vehicular homicide back in July, admitting after he smoked pot and was speeding when he caused the crash that killed four of his friends on the Southern State Parkway in October of 2012.

While it is illegal in all states to drive while impaired by marijuana, not every state tests drivers involved in fatal crashes for drugs. Especially if the driver has already tested positive for alcohol. Safety experts say that needs to be changed.

So far, Colorado and Washington are the only states where marijuana is legal for recreational use. Efforts are underway in Alaska, Massachusetts, New York, Oregon and the District of Columbia.

Most states do not have a specific level set yet where a person would be considered intoxicated by marijuana.
