You’re gonna have to provide sources, as the closest thing I could find to back up your argument was CCC paragraph 2291, which doesn’t mention marijuana by name.
Why do you think recreational drinking is okay but pot smoking isn’t? Alcohol kills people: I sent a lot of people to the hospital for alcohol poisoning when I was an EMT. I happen to be a medical marijuana user, and smoking pot beyond a certain threshold just puts me to sleep, and I wake up feeling fine. It’s not something everyone should do, but it’s certainly not heroin, prescription opioids, or even alcohol.
