Since marijuana is now legal in several places, cops have been forced to come up with ways to tell if you are driving under the influence. The police have come up with some interesting ways to establish if one is driving under the influence thanks to the lack of a straightforward test. If you reside in a location where marijuana has not been legalized, it is an offense if you have it in your car or system. Cops are working on finding ways to determine if the drivers that are pulled over are driving under the influence of marijuana. If you want to know what an officer will do if they suspect you are under the influence, you can learn more about it by reading more here.
The first option they can use is the breathalyzer. There are presently no breathalyzer tests that can tell if someone is under the influence. The main reason for this is the fact that the amount of marijuana in your system does not correlate in any way with your impairment. A simple drug test cannot establish your level of impairment from THC like it does with alcohol. A marijuana breathalyzer that can be used on people suspected of being under the influence has been reportedly invented by a California doctor. There is no information on whether it will be used in future although it is not under use currently. Though it will most probably be for alcohol, there is a possibility that a police officer will have you take a breathalyzer test if they suspect you are under the influence.
A urine test is another option that they could use. In some areas, you automatically consent to a urine test if the officer on duty suspects that you could be under the influence. They may ask you to provide a urine sample if an officer believes that you are driving under the influence. This has its disadvantages as well. This because THC can stay in your body for up to a few days after smoking. If an officer fails to prove that you were high or you failed a field taste, this may not be enough to incriminate you.
An officer can see if you have THC in your system by using a mouth swab. Just like the others, these tests are not any accurate either. It is therefore impossible for cops to use them to prove that you are high. If a police officer has no other source of proof, it is almost impossible to charge you for driving under the influence.
