June 11 (UPI) -- High-potency marijuana flower and concentrates don't get users any more intoxicated than lower potency forms, according to a study published Thursday by JAMA Psychiatry. While users of marijuana concentrates have blood levels of tetrahydrocannabinol, or THC, more than twice those of who smoke flower, their self-reports of intoxication, or "feeling high," were remarkably similar. So were their measures of balance and cognitive impairment, the authors found. Advertisement THC is the main psychoactive component of marijuana. "Surprisingly, we found that potency did not track with intoxication levels," study co-author Cinnamon Bidwell, an assistant professor in the University of Colorado-Boulder's Institute of Cognitive Science, said in a statement.
