Marijuana has been legalized in several states in the United States, leading to an increase in the number of users. As much as it is legal to use marijuana, it is illegal to drive while under the influence. Marijuana impairment test are used to determine if a driver is intoxicated to prevent accidents. This blog post is a basic guide on the different types of marijuana impairment tests.
Field Sobriety Tests
Field sobriety tests are administered to assess the general state of a driver by observing their physical and mental attributes. This type of test has been in use for a long time, and it informs an officer whether a driver is intoxicated. The test is administered by the side of the road, and the police officer looks out for signs such as the driver’s speech, balance, and coordination. The driver is given instructions to follow, such as walking and turning, and the officer observes to see if they can execute the task.
Blood Tests
Marijuana blood tests are used to determine the presence of THC (tetrahydrocannabinol) levels in the blood. THC is the active ingredient in marijuana that causes psychoactive effects. Blood tests are a more scientific way of determining the level of intoxication. However, the results can be inconclusive due to the variance in individual tolerance levels. THC levels in the blood can remain high for up to 7 hours from the last pot smoked.
Urine Tests
Urine tests are commonly used in marijuana testing and are more convenient and affordable to administer. The tests are sensitive to THC levels in the urine, and it can detect marijuana use up to 30 days after using it. Urine tests are, therefore, not a reliable way of determining marijuana intoxication at the time of driving but rather a method of detecting any marijuana use.
Saliva Tests
Saliva tests are a relatively new form of marijuana impairment testing. The tests are non-invasive and can detect THC levels in a driver’s saliva. The tests are generally accurate, and more police departments are adopting it because of its accuracy and convenience. However, THC levels in the saliva reduce faster than in the blood, making the results time-sensitive.
Breathalyzer Tests
Marijuana breathalyzer tests are a scientific way of determining THC levels in the breath. The tests work by detecting the presence of THC in vapor expelled through the user’s breath. The tests are non-invasive and can be administered anywhere. Marijuana breathalyzers are, however, not readily available, but with the recent legalization of marijuana, companies are calling for their creation.
Conclusion:
Marijuana impairment tests are an essential tool in maintaining road safety despite marijuana legalization. It is crucial to learn the different types of tests available to understand what to expect. Blood tests are more accurate than urine tests. Saliva tests are more convenient and accurate than urine tests. Field sobriety tests are still a reliable way of assessing the general state of a driver. Breathalyzer tests are not readily available, but there is a need for them. It is essential to avoid driving while under the influence of marijuana to prevent accidents and legal consequences.
