A recent study suggests the amount of THC in someone’s system is not an accurate predictor of impairment. The study , conducted with the support of the National Institute of Justice, involved 20 participants in the U.S. They were asked to consume cannabis through edibles or vapes, all with different levels of THC. Afterward, the subjects were tested with common field sobriety tests and asked to complete cognitive tasks. According to the study’s results, the amount of THC wasn’t a reliable indicator when discussing a person’s impairment. This is important since it questions many of the rules revolving around cannabis use, particularly with respect to impairment when driving.

The data didn’t correlate with the cognitive tasks and field sobriety tests in which the participants took part. Some individuals had low levels of THC and performed poorly on these tasks and vice versa . THC has long been the focus of impairment rules and discussions. Now that more U.S. states are legalizing the plant for recreational use, this is a problem, since it may result in the arrests of people who aren’t actually impaired. Currently available drug…
