Professionals say Washington state's enjoy will be a lesson for rest of united states of america.
The number of deadly automobile crashes concerning marijuana greater than doubled after Washington nation legalized the sale of the drug, a new observe finds.
Marijuana have become legal in Washington in December 2012, researchers said. Among 2013 and 2014, the percentage of drivers in Washington involved in deadly car injuries after using marijuana rose from 8 percentage to 17 percentage, in line with the look at from the AAA basis for visitors safety.
In 2014 by myself, one in six drivers worried in a deadly crash had recently used the drug, researchers located.
"The tremendous growth in deadly crashes related to marijuana is alarming," Peter Kissinger, president of the AAA basis for visitors protection, stated in an AAA news release.
"Washington serves as an eye-establishing case have a look at for what different states may revel in with avenue protection after legalizing the drug," he added.
At least 20 states are presently thinking about marijuana legalization, the researchers stated. Washington, Alaska, Colorado, Oregon and Washington, D.C., have already legalized the leisure use of the drug.
The drug has also been legalized for healing and medicinal use in 20 states, researchers said.
Whether or not or not marijuana is legal, no person need to force underneath the affect of the drug, the researchers mentioned. But it's no longer but precisely clean how lawmakers need to address the problem.

On the way to manipulate drug-impaired driving, some states have hooked up legal limits for the drug.
Those policies specify the highest degree of energetic THC -- the main component of marijuana -- that drivers can legally have of their device. Energetic THC within the bloodstream commonly suggests that a person has these days used marijuana, take a look at authors said. THC influences the thoughts and might impair people's capability to power properly, the researchers cited.
Montana and Washington state have applied a prison limit for marijuana at 5 nanograms in keeping with milliliter (ng/mL). In Colorado, a blood concentration of at least 5 ng/mL manner it's possibly someone became using beneath the influence of the drug, the researchers stated.
In the meantime, Nevada and Ohio have set a limit at 2 ng/mL. Pennsylvania's felony restrict is lower at 1 ng/mL.
Twelve states have strict criminal limits that prohibit the presence of any levels of marijuana in drivers' blood, the observe authors said.
After investigating the lab results of drivers arrested for impaired using, the researchers located many problems with legal limits for marijuana, consisting of:
there may be no reliable clinical evidence that drivers end up impaired once they have a particular level of marijuana within the blood.
Numerous degrees of marijuana have distinctive consequences from one person to the subsequent. For a few people, low THC degrees may additionally result in impairment. Different humans, however, might not be impaired in spite of excessive levels of marijuana in their system.
Marijuana within the blood may additionally drop to a criminal restrict earlier than a suspected impaired motive force is tested. On common, it takes more than two hours to take blood from a motive force because it calls for a warrant and people ought to be transported to a lab for checking out.
"there may be understandably a strong desire through both lawmakers and the public to create legal limits for marijuana impairment, inside the same way as we do with alcohol," said Marshall Doney, AAA's president and CEO.
"inside the case of marijuana, this approach is flawed and now not supported by means of medical studies. It's in reality no longer possible nowadays to decide whether a motive force is impaired based completely on the amount of the drug in their body," Doney stated.
In preference to depend on limits of THC inside the blood, AAA recommended states to use a -pronged technique to put in force drug-impaired riding. This method might consist of:
A tremendous check for latest marijuana use.
Behavioral or physiological signs that a driver is impaired.
The researchers referred to this approach could rely closely on law-enforcement training programs that help officials understand drug-impaired riding.
"Marijuana can have an effect on driving force safety through impairing automobile control and judgment," stated Doney. "States want consistent, sturdy and honest enforcement measures to ensure that the accelerated use of marijuana does no longer impact street safety."
