I live in a state where it was decriminalised a few years ago.
There was obv a huge pent up demand.
The state taxes sales. Growers have to be licensed. There were efforts to assure racial equity in the issuing of licenses. People who want to buy it and other pot based products including delivery items (for vaping) can choose from a variety of options - it's quite an industry, employing a good few people, all contributing to the economy.
I don't see drugs and alcohol use as moral issues. I think the 'war on drugs' is a massive and unconscionable waste of public money thst has devastated many communities. All of the problems associated with the illegality of drugs were amply demonstrated in the US during Prohibition - the rise of the Mafia, horrific crime, ruined lives. Yet on either rside of the Atlantic politicians appealed to the same moral panic and launched the war on drugs, and worse, kept at it for decades even though it was perfectly obvious that it was having exactly the same results as Prohibition. Yes, Al Capone got his comeuppance, but the network of criminals he and others built endured and blighted American cities for decades, amd continue to do so and to inspire others to this day.
My late FIL was a surgeon who was on call once every four weeks, and frequently got the call late in the night to get tot he hospital for yet another surgery on yet another young person whose life would never be the same again thanks to the buying and selling of illegal drugs and surrounding violence.
He was an advocate of legalising all drugs, controlling sale through state run clinics where users could access various services to help them get clean, amd help their families. He was also conscious of the toll illegal drugs have on the law and civil society of countries where drugs are grown - Mexico, most of Central America, Colombia, Afghanistan, etc. Those places are tightly in the grip of criminal gangs, politics are corrupted, and the lives of ordinary people are very, very difficult. I think his arguments made a lot of sense.
