The rise of fentanyl trafficking is largely a result of prohibition. Imagine you are a drug smuggler. Now would you rather have truck load worth $100k or a briefcase worth $100k?
Sort of, but the calculus changes. In a regulated market, costs are likely to be dominated by the cost of the product, cost of service, regulations and taxes - shipping a truckload of product legally isn't going to come close to that. But with illegal drugs, cost of transport is one of the biggest contributors to cost, and so taking steps to minimize that is worthwhile.
For instance, cocaine costs ~2k/kg in backcountry Columbia, but ~20k/kg in US cities [0] (at least at the time the article was researched). And when your transport costs dominate that much, almost every way to reduce volume and weight is justified.
Transporting a truck of legal goods across a whole continent and multiple countries is much cheaper and easier than a briefcase of illegal drugs.
The total cost of risk-free (i.e. fully insured) delivery of a truckful of goods is trivial compared to even quite cheap products; while that briefcase would pretty much have to double in value after that long trip to make the transport profitable.
That briefcase will increase in value ten fold over the journey. So my point stands, easier to transport the briefcase and the returns are better. The risk is higher but that is why the returns are higher.
Probably? Hospitals use fentanyl all the time and I’d imagine they have no problem with dosing. It’s probably pretty great to have enough pain killers on hand for an entire hospital and not needing 100x the space (or whatever the scale is)
Guns are pretty heavily regulated in the US though? Many kinds you can't buy at all, and those you can require background checks. (A lot of people seem to think that there are fewer restrictions on guns than there actually are, and that's before you bring individual states into the equation)
It's just everywhere else is even more outrageously restricted, which makes the US look liberal in comparison...
But to call guns unregulated in the states is to say that cars (among many other things) are completely unregulated too.
