A leading law professor has ignited controversy by declaring that current roadside tests used to detect marijuana impairment are “pseudoscientific” and legally flawed. The bold statement was made during a legal policy discussion as more states face scrutiny over how cannabis impairment is measured—and prosecuted—on the road.
The criticism targets field sobriety tests like eye movement tracking, balance tests, and coordination exercises. These methods, often adapted from alcohol-based enforcement, are widely used by police officers to detect cannabis impairment. But unlike alcohol, THC behaves differently in the body—and can remain in the system long after impairment has passed.
Experts argue that THC levels don’t reliably correlate with functional impairment. A person may test positive for cannabis days after consumption, even if they are completely sober at the time of testing. This disconnect has already led to controversial arrests, court challenges, and even wrongful convictions.
The law professor emphasized that these tests not only lack scientific validity, but they also risk violating individual rights. Inaccurate impairment assessments could disproportionately affect medical marijuana patients or legal adult users who are obeying the law but still flagged during traffic stops.
Calls are growing louder for a new approach to cannabis impairment testing—one that is based on real-time cognitive or motor-function analysis rather than outdated THC thresholds. Technology and research are starting to catch up, but many states continue to rely on methods that legal experts now say may not stand up in court.
This issue has massive implications for cannabis legalization, public safety, and the rights of consumers. As more Americans use marijuana legally—whether for medical reasons, wellness, or recreation—accurate, fair roadside testing is critical.
At High Science, we stand for truth, reform, and justice. We believe that outdated testing protocols shouldn’t ruin lives or set back the progress of cannabis normalization. Through daily cannabis news, fashion-forward marijuana clothing, and hemp-based culture, we fight to replace fear with facts.
Pseudoscience has no place in modern cannabis law. It’s time for data-driven solutions that respect both safety and civil rights.
