Summary:
Heroin will go through the fucking roof and get scarce. Opioid Crisis is effectively over in a few years. tl;dr there is still a huge backlog of poppy juice in or on its way to Russia. Once that is through, there is going to be a huge heroin drought think late nineties pricing/availability. If you an addict, start buying now and give it to someone who will dole it out to you slowly.
If you are just a degenerate junkie 'psychonaut' (AKA waste of flesh), no worries. Alternatives like fentanyl will soon take up the slack. Talk to your deal today and start shopping for something else to get your fix. I personally recommend drain cleaner.
Long, Gay Post:
There is a small chance the Taliban will keep the poppies going, but this unlikely. Working with 'International drug control' (DEA) will be a legitimate revenue stream and international clout building. If the Taliban somehow manage to not completely wreck their Tuccanos & Mi-17s in the intervening period, they will use that as leverage for international support to get and keep these aircraft operational to help in drug fighting ops - and then use that expertise to use the airframes to launch airstrikes on insurgents.
The will be leaving a lot of 'dirty money' on the table, but that was not a big concern for the Taliban. They were never about exporting Jihad (except to Pakistan and Iran), and the new leadership seems much more savy about not giving anyone outside a reason to come in. They would rather have 'clean' money they can buy things with openly.
This is going to dry up the supply of opiates. Just going from how long it took for Afghan White to hit the streets, and assuming the (primarily) Russians are going to be metering their supply (fewer, higher-success smuggling ops, not longer a customs blitz) I'd guess 5 years but that's largely out my ass.
Horse is still going to be available, but it'll be harder to get, especially in quantity, and stepped on to shit. Basically just ask any old timer around a Jazz club what it was like trying to score decent Jazz Juice in the 90s and that'll be a pretty good estimate of what's coming.
Drug cartels will just shift to something else, very likely a new wave of Chinese "research" chems. Venezuela might have its time to shine by renewing the interest in Coke and leveraging Biden's non-existent border. With the collapse of FARC, there is less of an impetus on grow ops.
Watch Equador/Columbia and if there's an uptick in violence, go long on Cocaine futures. Eye on Mexico too, but uptick there could mean anything.
There are of course some X factors in this.
There is a lot of money that will be going up in smoke. Glowniggers and Russian Mobsters will have a huge interest in not seeing opium dry up - they may be able to get some of the more flexible warlords to openly revolt and possibly assassinate current leadership.
These projections are based on previous Taliban exploits; as mention many times these are not your father's Taliban. past performance goes not guarantee future returns.
You read all that and are now gay.
if previously gay, you are now a furry.
Haha, just kidding I know you were already a furry. So you're now Mormon.[/spoiler]
Afghanistan getting out of the busisness creates market suction.
If the McDonald's across town closes, you will see a lot more people stopping at your burger king.
