Blood-THC level ‘poor indicator’ of impairment

Blood-THC level ‘poor indicator’ of impairment

According to a panel discussion held in Colorado, one of the states that
recently legalized marijuana for recreational use, measuring the blood-THC
level is a “poor indicator” of driving impairment.

Lawmakers want to prevent bad driving, whether it’s from alcohol
or drugs, and are seeking ways to determine impairment for drivers pulled
over for driving under the influence of marijuana.

The amount of THC (or “tetrahyrocannabinol,” the psychoactive
ingredient causing the “high”) in the bloodstream has been
considered for a long time to be one way to measure impairment, but this
method has its critics.

In fact, Greg Campbell’s story in the Daily Caller describes a doctor
who said his patient was “in no way incapacitated” after a
blood test showed the patient’s THC level was three times above
the limit proposed by Colorado lawmakers. (This patient smoked marijuana
for medical purposes daily.)

Lawmakers want something to work with, some way to prosecute people for
impaired driving because of marijuana. On the other hand, that “something”
should be based on common sense, not an arbitrary number.
