I don't have a link. It was a special on TV. Basically it followed a few families that had children with severe autism and none of the drugs that they tried were affective so they tried CBD. After telling their doctor that it helped they moved to try and get it approved by the FDA. There is currently only one FDA approved drug containing CBD and it is only for autism. All other CBD is not regulated but does undergo third party laboratory testing to regulate THC levels. That's why it's so expensive because the FDA doesn't test it.
How does CBD help autism, do you know? Or have a link?
