Here’s what they should use: Carfentanil.
Carfentanil is so powerful most vets and zoos keep less than 20 grams of it around at any time. Dogs that catch a whiff of it can die instantly. It’s 100 times stronger than the painkiller fentanyl and between 5,000 to 10,000 times stronger than morphine. The equivalent of few grains of salt of carfentanil is enough to kill an adult human.
Just wait. Carfentinal will end up being sent via mexico or China to our fantastic free addicts soon enough.
Yeah baby!
