I agree with what you have written here but just want to clarify that the only physically dangerous drugs to quit cold turkey are alcohol and benzos such as xanax, ativan etc.

There are treatments/protocols for quitting every drug that exists but those are the only ones where you have to be in an inpatient clinic because of risk to your physical health.

There are legal options for quitting opioids that include methadone and Suboxone and they are highly effective for many people. Countless people I know, including myself, credit these drugs to saving our lives. Thankfully access has become much easier for Suboxone post COVID and it shouldn't be too hard access. To me drugs should be legal because it's a safety issue. Plenty of people have no desire to quit and that's fine. Giving them heroin for free is a cost effective way to give people dignity as well as save society a lot of money and unnecessary tragedy. People will still overdose and die but hopefully not in the numbers we are currently seeing. Even if it didn't help the overdose problem though there are still many strong arguments to be made in favor of legalization imo.

Good question.
I have been to a few dozen Grateful Dead Shows.
I have seen my share of bad trips. It was almost one per show in the 80’s and 90’s.
I also went to college at one of our state schools. I would never admit that it was a party college. I saw one or two people get pretty messed up from acid. One guy was having mental health issues and took acid often. It triggered his other issues in a bad way. He left school. Rumors said he was no Longer able to function for years.

Probably because you'll think you're a glass of orange juice and jump out the window /s
