High-potency marijuana concentrates on today’s legal markets can contain upwards of 90 percent THC, so one might reasonably expect them to pack a greater psychoactive punch than typical flower, which tops out around 30 percent.
But that may not be the case, according to a new study out of the University of Colorado at Boulder.
Researchers found that while THC blood levels spiked after users consumed concentrates, impairment levels didn’t significantly differ from participants who used flower.
“Surprisingly, we found that potency did not track with intoxication levels,” said lead author Cinnamon Bidwell, an assistant professor in CU’s Institute of Cognitive Science. “While we saw striking differences in blood levels between the two groups, they were similarly impaired.”
