Many parents and some clinicians believe that marijuana can alleviate certain symptoms of autism, science writer Emily Willingham wrote Wednesday on Forbes.com. Some anecdotal evidence seems to support this claim, but Willingham underscores the caveats of this untested (and, in many states, still illegal) line of treatment. She points out that none of the limited number of studies she found verified a benefit for people on the spectrum.
At the same time, Willingham writes, there could be irreversible negative consequences for children whose parents medicate them with marijuana. She concludes that although some compounds in marijuana might be safe and beneficial for people with autism, conducting scientific research to address these questions is the only way to find out for sure.
