The US Journal of Surgeons published a study by Wright State University.
The study said that over 40% of victims involved in fatal car accidents over the past six years had higher doses of THC in the blood well beyond some of the state’s legal restrictions.
“We’re driving at a high rate while the number of marijuana users is growing, and we’re sacrificing their lives,” the study said.
Doctors involved in compiling the data said THC delays reaction times, cloud judgments and dull adjustments. And that delay of seconds can be the difference between a near miss and a fatal crash.
Other doctors noted that most people involved in the destruction of cars likely consumed marijuana during the period close to driving. “This is not about residual use, it is about recent consumption,” one doctor said.

The results of this study showed that it is generally discussed among people in the health community who oppose marijuana legalization.
And it’s a way to slow down the way that reaction times, cloud judgements, dull adjustments, and a few seconds of cloud clouds can be the difference between near misses and fatal crashes if the driver is higher from an increase in THC levels. Also, doctors point out that even individuals who may have high resistance to THC may have slower reflexes, unreliable judgments, and narrow focus.
The Highway Safety Insurance Institute says its research shows that legalization of recreational marijuana is the driving force behind thousands of car accidents each year, with the percentage of cannabis-involved crashes generally rising after legalization in various states. This increase is particularly noticeable in fatal crashes.
