Hawaii is among many states deciding how much marijuana a driver can safely consume before getting behind the wheel of a car. With legalization growing both medically and recreationally nationwide, this is an issue that many lawmakers want to tackle now.
The State Department of Health is currently studying whether a person can safely drive under the influence of marijuana, and the findings will lead to a determined limit for consumption of the drug before driving.
Considering the fact that cannabis has the potential to stay in the blood stream for days, or even weeks, a blood test is ruled out for detecting the amount of marijuana one may be under the influence of. Therefore, it is hard to determine what role marijuana has played in previous accidents where cannabis has been found in the bloodstream.
Colorado, Montana and Washington have already set the legal limit of THC to 5 nanograms per milliliter of blood, while Nevada and Ohio went lower with 2 nanograms. The difficulty then becomes how to test this amount in the bloodstream without doing immediate blood work.
All states will continue to conduct marijuana research on this issue until a well studied amount is agreed upon.
