No. The drug warriors are neither humane nor sensible. Opioids are actually not all that dangerous, but the range between high and dead is not all that great. When you know what you're getting (chronic pain patients) the problem rate is low.
But with the street you get varying purity. And the drug war has caused the manufacturers to move to more concentrated products to make smuggling easier. And fentanyl has a very nasty property: the tendency to clump. This is no problem for the pharmaceutical industry, but when you have a dealer mixing stuff it's easy for a lethal clump to remain in the product. You get that, you better hope somebody nearby has Narcan.
You don't see it killing the pain patients like it kill the people on the street--this is a dose problem, not something inherent to the drugs.
And why is that a reason, anyway? There is no question as to the most deadly recreational drug: tobacco. Yet it's legal. Protecting the user is clearly not the motivation. (The data isn't so clear on the second because the data is so contaminated, but it looks like it is alcohol.)
Also, the majority of crime traces back to drugs. Remove the drug market, you cut the crime rate in half overnight. And there's no question the drug war causes a lot more harm than the drugs.
I can see no reasonable justification for the low-addictive stuff not to be legal. The highly addictive stuff you can make an argument for it being legal with a prescription, addiction is a valid reason for a prescription. It has been handled that way in the past in England and worked well. In in ideal world I would favor this approach, but I have a sufficient distrust of the politicians to trust this wouldn't become full of obstacles.
Amsterdam's experience with legalization says that it doesn't increase use, but advertising does.
Thus, what I would like to see:
General promotional stuff is limited to simple item-price listings. Nothing more can be presented unless the customer has already demonstrated interest, either by entering a website (and the insides of the website can't be bookmarked, you must enter the gate each visit), or by entering a portion of a store devoted to that drug. Externally there must be a minimum of information needed to identify what the business is.
The selecting your stuff part can never be mixed, you want two different types and you must visit both places even if they have a common checkout.
The same rules apply to all recreational drugs, including tobacco and alcohol.
