Fentanyl
From The Soysylum
Fentanyl is God’s answer to the question “how strong can I make this opioid?” And it is a great answer indeed. Fentanyl excels at treating victims of psoychosis, as well as curing niggers of life, and making white dudes nod out in transit stations.
even doe Carfentanil is 20-100 times stronger than Fentanyl therefore it's le better or something
