From the article:
Today, a key working group of the United Nations Office on Drugs and Crime (UNODC) announced the release of groundbreaking recommendations discouraging criminal sanctions for drug use. The Scientific Consultation Working Group on Drug Policy, Health and Human Rights of the UNODC – which includes Nora Volkow, head of the U.S. National Institute on Drug Abuse (NIDA) – is releasing the recommendations at the High-Level Segment of the 57th UN Commission on Narcotic Drugs. The working group recommendations say “criminal sanctions are not beneficial” in addressing the spectrum of drug use and misuse.
It seems likely that very heavy cannabis use starting in adolescence and continuing for many years can lead to measurable decreases in some cognitive abilities. It is possible that occasional use might also cause damage, but right now there’s no strong evidence to back that claim. On the other hand, it is certain that participation in high school and college football leads predictably to brain damage. So: If cognitive harm from cannabis is a good reason to support continued criminalization, would you support a ban on high school and college football? And if not, why not?
