Brain scans could replace breathalyzers to catch stoned drivers

A new study has identified a pattern of brain activity that seems to correlate with impairment from cannabis intoxication. The researchers suggest this novel brain-based biomarker could be a way to accurately measure THC impairment.

The metastudy looked at 28 published studies and concluded there is no strong or consistent link between THC levels in blood or saliva and driving impairment

Blood or saliva THC levels found to be poor sign of driving impairment

A new meta-study has concluded blood or saliva THC concentrations are not effective ways to measure cannabis-induced driving impairment. The findings indicate impairment tests should be developed instead of looking to develop a marijuana breathalyzer.

A study has found no differences in intoxication or impairment between those smoking high-THC concentrates and those smoking lower-THC flowers

Study finds stronger marijuana doesn’t lead to higher levels of intoxication

A study has found smoking high-THC marijuana or concentrates does not result in greater levels of intoxication. The research adds weight to a body of evidence suggesting proposed roadside THC tests may not correlate with driving impairment.

New research shows breath THC levels can correlate with blood THC levels, but does this offer authorities an objective way to catch stoned drivers?

Marijuana breathalyzers are coming, but will they work?

With marijuana breathalyzers closer than ever, authorities are arguing over whether THC levels correlate with driving impairment.
