In Colorado and other states where medicinal or recreational marijuana has been legalized, police officers are changing the way they conduct traffic stops where they suspect impaired driving. They plan to perform a variety of tests that help prove a driver is intoxicated with THC since it is tough to prove with just a blood test. They may record information related to driving behavior, smell, dilated pupils, and the presence of marijuana paraphernalia.
People who are arrested and charged with driving while under the influence of drugs or alcohol may be given the opportunity to defend themselves against the charge. There are many different ways in which an individual may do this. For instance, he or she may use an affirmative defense by claiming that he or she was forced to drive or that driving was a necessary evil. Other affirmative defenses include asserting that an individual was entrapped or became intoxicated without consent.
There has always been a debate on whether marijuana use affects a person's ability to drive. However, the Insurance Institute for Highway Safety (IIHS) recently reported that the four states that legalized the use of recreational marijuana have experienced up to a 6 percent increase in motor vehicle crashes in recent years.
