Nah, trying to use the doctors and access to them as  means to shut off the valve never works. The system as a whole is way too leaky and greedy.

Look it may be time to rethink this.  What if we just give these people the pills when they want them. It's not like they are going to have much to do in the coming decades. Their role in the economy is as a vehicle for consumer spending and they already get  a large portion of the cash for that from government entitlements.  In a decade or so ther will be no jobs for them anyways what with the coming revolution in automation. So its not like having them all gooped up on gop is going to interfere with any productivity. Heck, a large part of the populace already spends most of their lives in a daze. And we are still the driving engine of the worlds economy.  The pills will make it easier to keep those that want them satiated. Just axe the moral component out of it and make it so everyone knows they will never run out.

In return for this guaranteed windfall profit, we should require the pharmaceutical companies to submit to negotiated pricing from group insurance plans. Opiates are cheap to produce, no reason they should bankrupt a average person to acquire. Whether they have insurance or not. These companies benefit from our economy and the stable market the USA provides, they should be required to contribute in kind.

In fact, why even bother with synthesizing the drugs? Plant based opiates like heroin are beyond dirt cheap. We pay to fight an endless  war to stabilize the world's supplier of heroin and business is better than ever for the opiate production in Afghanistan. Lets let big pharmaceutical source there from the poppies growers we effectively provide agricultural subsidies for. Probably our most effective agricultural subsidy program ever  for holding the retail price down. The US Military is clearly extremely effective at this kind of thing when they put their minds to supporting a nation's regime.

So let's reap some benefits from the last decade and a half of war and require our drug companies to make cheap Afghan smack. At least till the agricultural industry can catch up and apply our automated farming tech to the problem and produce it even cheaper and better. Its a win/ win. In fact I think the profits will only go up as the price goes down, production costs are reduced, the middleman is cut out and sales volume goes up as people can have non-demonized but managed access. This could be so effective we will get tired from all the winning.
