I know someone with cerebral palsy who's life has been changed so much for the better now that she has medical marijuana clearance. She can't afford the full meds she's allowed, but she does the oil when it gets bad, and it relieves the spasming and pain.
She used to smoke pot to get the relief, but hated it. The CBD oil with less THC is milder and she likes it a lot better.
The evidence showing lower opioid use with THC availability seems to indicate it would be in the public's interest to decriminalize, or legalize.
