Sabrina and Tim Mattis say medical cannabis has been a game changer for their 9-year-old daughter Krystal, who has autism spectrum disorder and epilepsy.
Arizonans with autism and post-traumatic stress disorder could add marijuana to their medical toolkit under a proposal that expands who can access the drug.
Researchers hope that this may have the effect of both encouraging further exploration of medical cannabis use for autism, and lead to a better type of cannabis being used.
