Indeed.
Quite the reverse. Wherever any prohibited drug has been legalized, this has led to a reduction in associated medical costs. That's true of pot in Amsterdam, Heroin in Portugal, and Alcohol in the USA.
We see it with oxy. Legal as all hell, prescribed by doctors.
And with alcohol and tobacco. Legal as hell, available at a wide range of retail outlets. Causes massive social harm, only outweighed by the even greater harm that arises when prohibition is imposed, with the resultant black markets, gang enforcement of contracts (because you can't ring the cops and complain if you get stiffed in a drug deal), and exposure of otherwise law abiding citizens to the criminal classes.
Pot has been legal in Seattle functionally for a long time and heroin has essentially been decriminalized.
Nether of these things is in fact true.
I was walking through a park a block away and passed a young man in his early 20s shooting.
That's terrible. Have you seen any drunks in your parks?
Along with wine and cheap liquor pot has been added to people hanging out on the streets. It is everywhere. You can not walk around downtown Seattle without smelling it.
And yet, the smell is harmless. If we outlawed everything that annoys grumpy old men, everything would be illegal - including your OP.
The next 50-100 years will see how it all plays out.
Having lived through the 60s 70s I had the idea hat it was purely personal choice. Not any more.
Your aging is nobody's problem but your own.
Our first opioid epidemic was in the 19th century. Opium was a traded commodity and was available over the counter in several forms. Opium dens where one could go, pay a fee, rrelax, and smoke opium.
Indeed. And prohibition has done nothing to mitigate any of its harms, nor to significantly reduce its availability, or its popularity.
Making things illegal generally doesn't stop people from doing them, nor from wanting to do them. When the harms chiefly befall the person who chooses the harmful behaviour, it is almost invariably better to make the facts available to the vulnerable, and to provide assistance for those who wish to kick the habit, rather than to criminalize their behaviour, and push them into routine lawbreaking.
The abolishing of prohibition - whether of alcohol or of any other drug - cuts organized crime off at the knees, improves public safety and public health, and is generally good for society. Only a blind fool could imagine that making (or keeping) a drug illegal would reduce its popularity - particularly when the history of American organized crime so amply demonstrates the pernicious effect of prohibition on society, whether the ban is on alcohol, cocaine, heroin, or any other addictive substances.
