Legislations have been put in place to regulate the use of cannabis while driving around the world. In some states in the US, while the use of cannabis is legal, there some laws which have been put in place to regulate drugged driving. Many activists argue that there is no scientific evidence to support laws that ban the use of cannabis while driving. This has led for the calls from Automobile clubs in the US for the scrapping of those laws on dangers of cannabis and driving The argument was based on the points explored below.
Inability to set blood-test limit for THC that can lead to impairment
The chemical that is responsible for making people high in Cannabis is called THC. Several attempts have been made to try and measure the level of THC among cannabis users to curb drugged driving. Laws of dangers of cannabis and driving have been put in place based on certain limits on THC concentration on blood. The laws consider those with higher THC compared to the set limit guilty of drugged driving, and those below the limit not guilty. Some foundation argues that these laws are bias as those who are guilty may be set free, while those who are not are sentenced.
The activists recommend that impairment level should be determined regardless of the amount of THC in blood. This is because people are believed to react differently to cannabis use. Some will be impaired even with a low concentration of THC in their blood while some may not agree with high levels. Therefore, recommendations are made on how to check on impairment rather than purely depending on THC level in blood.
Lack of scientific evidence on the relationship between THC level and impairment
It is complex to determine the impairment as a result of cannabis use, rather than merely using it. There is no scientific evidence that shows that drivers become impaired at a certain level of THC in their blood. Regular users of cannabis may show high levels of THC and still not have impairment on their system. Therefore the laws based on THC level may be biased to this group of people.
Blood testing also takes time before the whole process is complete. The law in states in the US where drug is legal require that warrant and transport of the drivers to the police station. The time may take around two hours, which might result from falling in THC levels by the time the test is done. Frequent cannabis users may test positive for THC in their blood long after using cannabis, while occasional users their levels may drop fast. Laws on the dangers of and driving in some states in the US are zero tolerant, yet the use of marijuana is legal. This makes no sense as frequent users will be disadvantaged because of the continuous presence of THC in the blood.
There is a need for change in laws on the dangers of cannabis and driving. This is especially in states which have legalized cannabis use. The laws prohibiting THC in the bloodstream is not fair, especially in states where the use of cannabis is legal. Much need to been done to ensure fairness for cannabis users.
