Personally I own shares in w-18 stock so I'd hate to see it tank in value!
Seriously though, these super potent opiates are on the market because of drug prohibition.
Look at it like this cownan: 1kg of carfentanyl is able to make 5000kg of "fake" heroin. 1kg of heroin is worth around $125,000 dollars. What's 125,000 x 5000? A lot. That 1kg of carfentanyl could be bought/made for as little as $10,000. That's 5000 kilos of fake heroin for $10,000.
Here's the crazy part: the legal consequence to having 1kg of carfentanyl are the exact same as having 1kg of heroin. Meaning if you were caught with a kg of carfentanyl you'd face the same punishment as you would for a kg of heroin. Yet the kg of heroin would only be worth $125k but the kg of carfentanyl could yield a value of $625,000,000
In a risk:reward ratio it makes total sense. Now let's say you had to smuggle it into the country, just like a kg of heroin. You face the same consequenc if your caught doing that, yet stand to gain a heck of a lot more if it's the carfentanyl verse heroin.
This was all predicted back in the early 2000s or maybe late 90's by a DEA agent named Donald Cooper who presented seminars to regional DEA offices called The future synthetic drugs of abuse. Google to read transcripts of it, he correctly predicted a lot of curren trends, because the prohibition of drugs would drive people in this direction and It has.
