However, even when legal, it is still an offense to drive under the influence of marijuana. As a Massachusetts OUI Defense Attorney, this creates problems as it is much more difficult to measure the presence of marijuana in the system opposed to alcohol. With an alcohol OUI charge, registering a .08 or higher will create a presumption that the driver was operating under the influence. There is not really a “magic number” such as this for marijuana and has created difficulty in OUI cases involving drugs. Colorado has recently taken on the challenge of trying to create a threshold for marijuana.
The effects marijuana have on driving is not as clear as the effect alcohol has which was a problem for Colorado law makers. However, they were determined to find a number to put on the amount of marijuana in a drivers system in order to make it more like an alcohol OUI. Colorado concluded that a driver will be assumed to be impaired if a blood test shows THC in five or more nanograms per milliliter. When a blood test shows this amount of TCH, it will be the same as blowing a .08 in a drunk driving charge.
Similar bills creating a standard like this for marijuana use have been met with some resistance. This is due to the small amount of research done on the effect marijuana has on driving and the intrusive nature of taking a suspect in for a blood test. Research has shown that the more marijuana used, the worse a driver will be performed. This is really the only data available and more will be available late this year.
As of now, some states such as Washington have taken the stance similar to Colorado and created a certain amount of THC in the blood that will show impairment. Others have taken a zero tolerance policy and will handout an OUI with any trace of THC in the blood. Commentators are more receptive to the Colorado and Washington standard as this gives defendants a chance to defend the charges and prove they were not impaired. Problems also arise with this view however as debated arise over whether this standard of five nanograms per milliliter is too high or low. It has been argued that the threshold is too low. People using marijuana for medical reasons will always have THC in their system and this can lead to people using marijuana responsibly and legally to face OUI charges.
When new laws changing what under the influence means, this certainly can create new issues for defense attorneys. It is important to note that this new law can potentially lead to problems with officers and suspects as well. Just because there is now a threshold, it should not lead to officers conducting these blood tests without probable cause. It is certainly an intrusive test to be administered to a driver and should only be given in certain circumstances when the police have a warrant under the Fourth Amendment.
