🏷️ Science 🌐 USA — The legalisation of cannabis reduced the use of cannabis by adolescents

Cannabis legalization for adults does not appear to increase cannabis use by adolescents and instead may have the opposite effect, a study suggests. To see how cannabis use by adolescents developed in states with and without such laws, researchers examined survey data on substance use collected from 1.4 million adolescents between 1993 and 2017. During that period, 27 states and Washington, D.C. legalized medical cannabis and seven states legalized cannabis for adult use.

Medical cannabis laws didn’t appear to influence whether teens used cannabis, the study authors reported in JAMA Pediatrics. Recreational cannabis laws, however, were associated with an 8% decline in the odds that adolescents would report trying cannabis in the previous 30 days and a 9% decrease in adolescents reporting frequent use. Reduced supply may explain why, said lead study author Mark Anderson, an associate professor in agricultural economics at Montana State University in Bozeman. “It may actually be more difficult for adolescents to obtain marijuana as drug dealers are replaced by licensed dispensaries that require proof of age,” Anderson said by email. “Selling to minors becomes a relatively more risky proposition after the passage of these laws.”

🌐 Israel — Government wants to ease access to medical cannabis

New steps outlined by the Health Ministry will make it easier for consumers of medical cannabis to access their medications, according to a ministry statement on 4 July. “We are attentive to criticism and to improving in order to ease the suffering of patients,” Deputy Health Minister Ya’acov Litzman said. “We will continue to promote further activities on the matter.” Part of the ministry’s plan is to supervise the pricing of cannabis to keep it under control.

“A large proportion of the patients will pay less than what they currently pay in the old system,” the ministry wrote in a statement. A fixed payment for pediatric patients and oncology patients will be set at around NIS 500 (about 125€), which will cover their cannabis medications regardless of the amount that they use. Under the new system, “prescription splits” will be allowed, meaning that patients will be able to purchase part of their prescription at one pharmacy and part at another.
