When Noa Shulman came home from school, her mother, Yael, sat her down to eat, then spoon-fed her mashed sweet potatoes - mixed with cannabis oil. Noa is part of the first clinical trial in the world to test the benefits of medicinal marijuana for young people with autism, a potential breakthrough. There is anecdotal evidence that marijuana's main non-psychoactive compound - cannabidiol or CBD - helps children in ways no other medication has. Now this first-of-its-kind scientific study is trying to determine if the link is real. Israel is ...one of just three countries with a government-sponsored medical cannabis program, along with Canada and the Netherlands. Conducting cannabis research is also less expensive here and easier under Israeli laws, particularly compared to the United States. Autism is one of the fastest-growing developmental disorders, affecting 1 in 68 children in the United States. Only two medications have been approved in the United States by the Food and Drug Administration to treat the symptoms of autism. Both are antipsychotic drugs that are not always effective and carry serious side effects. Adi Aran, the pediatric neurologist leading the study, said nearly all the participants previously took antipsychotics and nearly half responded negatively. Anecdotal reports of autistic children who benefited from cannabis ... led Aran to pursue more scientific testing. After seeing positive results in 70 of his autistic patients in an observational study, Aran said, OK we need to do a clinical trial."
