Wow, thank you!  How is this stuff even legal?

If you don't have time to use the link, some snips:

Last summer, the DEA warned law enforcement across the country that fentanyl ... could not only kill drug users but officers exposed to small amounts. 

“It only takes one granule [of carfentanil] to kill an adult,” 

Drug dealers, in an attempt to stretch their supply and deliver a stronger, longer high, are cutting heroin with the two substances.  Fentanyl is said to be 50 to 100 times more potent than morphine, and carfentanil is 10,000 times stronger than morphine.

“Think about this,” Lane told “Inside Edition.” “Nobody sees that on his shirt. He leaves and goes home, takes off that shirt, throws it in the wash. His mom, his wife, his girlfriend goes in the laundry, touches the shirt — boom. They drop. He goes home to his kid. ‘Daddy! Daddy!’ They hug him — Boom. They drop. His dog sniffs his shirt, it kills his dog. This could never end.”
