The stuff the pill pushers write scrips for are way worse and more addictive so I don't get why they would be so against it. I mean I get that and I am a conservative and have never taken a toke in my life.
Honestly, it’s part the pressure of certain special interests (bourbon, pharma, law enforcement) and part the stigma from older ways of thinking.
My parents are in their late 70s. Both were “devil’s lettuce” type my whole life because that’s what they were taught. When I was 18 they found a small bag of (bad brown) weed and a pipe in my room and you would’ve thought I was strung out on crack robbing liquor stores by their reaction. Then, 20 years later, one of their closest friends - a retired career Army man and Vietnam vet - was diagnosed Stage III pancreatic cancer with metastasis and he used cannabis to help with pain and nausea/low appetite after chemo/radiation. The prescription meds made him sicker. The plant helped. He lost his battle, but was able to get a little relief in his final months. That really changed their tune and they’ve admitted they were taught bad propaganda in school and now support medical use and responsible adult recreational use.
I keep some on hand most of the time. It helps my migraines more than any pill I’ve taken and is probably the best cure for insomnia out there.
