Yes, the Cartels are getting it from Afghanistan. Right there is a connection/alliance we need to be keenly aware of. Furthermore, under Bush, DEA deployed with our troops in Afghanistan. When Obama scaled everything back, he opened the floodgates and facilitated the opioid epidemic.
This is the untold story in this HuffPo article.
To my understanding most US heroin comes from fields in Mexico and central America. One of the reasons they are lacing it with fentanyl/carfentanil is to reduce exposure. They can get by with smaller poppy fields and less people harvesting poppies when they can stretch it out with something from a lab. Also non-laced heroin then won’t cut it for users won’t cut it so they have to go back to that dealer who has the laced supply.
