There is Not a Correlation Between Blood Levels & Cannabis Impairment

Updated: Feb 6, 2020

Below you will find a couple of quotes from the Department Of Transportation National Highway Traffic Safety Administration report to congress from July of 2017 regarding Marijuana Impaired Driving. You will also see a link to the entire report below those 2 quotes.

In this report there are some blatant and obvious challenges presented to law enforcement in regards to prosecuting these cases. They go to great length to explain that the science does not support the theories presented by the assumptions that marijuana causes increased crash risk or impairment at all in drivers. In fact, time and time again, in every part of this report regarding the many studies done on this subject, they report inconclusive evidence and even evidence that shows marijuana may make people safer drivers!

There is no correlation between blood levels and impairment in regards to cannabis. This deflates all of the science behind blood tests being used to convict people. The system is broken. This continued push to utilize DRE officers to prosecute innocent people is a transparent slap in the face to every citizen in this country. Science is science. Evidence is evidence. Opinions and inconclusive reports by these DRE officers to fabricate cases against innocent people is an absolute and certain outcome. To intentionally place innocent people at risk of arrest to maintain conviction rates without any scientific support is absurd.

The continued gap between reality, science, and our courts is growing wider and wider with each and every one of these convictions and arrests. Take the time to read this report and understand exactly what these tyrants are doing to us. Take the time to stand up and say no to this politically influenced science and demand that reality is restored in our courts.

A couple of quotes from the report mentioned above:

"Continue Research to Enable Development of an Impairment Standard for Driving Under the Influence of Marijuana, and in the Meantime, Maintain Training and Other Support to Enable Law Enforcement Officers and Prosecutors to Pursue Cases Using Available Evidence. As the previous sections of this report have indicated, the poor correlation of THC level in the blood or oral fluid with impairment precludes using THC blood or oral fluid levels as an indicator of driver impairment. The use of BAC or BrAC as an indicator of driving impairment has assisted law enforcement and prosecutors in being able to show that an alcohol-impaired driver has a BAC that has been demonstrated to increase crash risk. The use of THC level cannot serve this same role for marijuana-impaired driving (Dupont, Voas, Walsh, Shea, Talpins, & Neil, 2012). 28 Toxicologists are not able to provide expert testimony that a specific amount of THC present in a suspect’s blood (or other specimen) is definitively associated with being impaired by marijuana and render the driver unable to drive safely."

" Recommendations Increase the Use of Effective and Efficient Methods for Training Law Enforcement Personnel, Including Drug Recognition Experts, to Detect or Measure the Level of Impairment of a Motor Vehicle Operator who is Under the Influence of Marijuana by the Use of Technology or Otherwise.
