As told by researcher Hamilton Morris, Fentanyl began as a cheaper alternative to longer lasting opioid medications but it’s synthetic nature allowed bath-tub chemists to attempt to make it.

Lacing heroin with Fentanyl makes it cheaper because there is less natural opium and more synthetic Fentanyl paid for by drug users.

Prince, pop star, took Fentanyl labelled as Vicodine (therefore counterfeit).

Users try Fentanyl illicitly because as mentioned the effect of Fentanyl is not as long lasting as other drugs.
