As New Yorkers go to the polls today to elect a new mayor, one of the leading candidates, Eric Adams, has expressed concern about the state’s new marijuana legalization law, saying it may “send the wrong message” to young people. Although Adams supports the law and legalization, he’s worried that it implies it’s okay to smoke a joint and go to school, or operate heavy equipment. He said it’s important to let people know about the medical benefits as well as the concerns related to marijuana. Legal pot has not been a hot topic during the mayoral campaign, except during one debate in which the candidates discussed whether to allow smoking the drug in public housing. Meanwhile, implementing marijuana legalization in New York may be delayed due to a tussle between Governor Cuomo and his critics over his nominations to the marijuana control board. Some accuse Cuomo of not being fully committed to legalization, although he negotiated and signed the bill. And finally, doctors report that an experimental treatment for drug addiction, known as deep brain stimulation, has helped one patient stay off drugs. If successful, the treatment—which involves inserting an electronic device in the brain—may also allow scientists to better understand the root causes of addiction and reduce the stigma that it is a moral failing. Yet for all the possibilities, deep brain stimulation does not address the psychological, social and socioeconomic factors that complicate the disease, and therefore remains on the outer edge of drug addiction therapy.
