The Netflix documentary series The Pharmacist tells the true story of a small town pharmacist—Dan Schneider—who beats massive odds to solve the murder of his son in a drug-related shooting in New Orleans. With almost no cooperation from the New Orleans Police Department, he accomplishes what they could not and sees his son’s killer sent to prison.

But months later, the ripple effects of his son’s addiction and tragic death find him confronted with a number of young, seemingly healthy people visiting his pharmacy with high-dose prescriptions for OxyContin.

Sensing a crisis long before the opioid epidemic had gained nationwide attention, Dan finds the source of these prescriptions: a pediatrician running a pill mill in his town. Again he refuses to accept the foot-dragging of law enforcement—this time the FBI, the DEA and the US Attorney—and figures out a way to bring this doctor down.

And Dan Schneider does not stop there.

His story is both heart wrenching and inspiring. One of the most vexing problems in our society is the scourge of legal and illegal drugs pushed by the dark souls that see it as their right to profit from them, as well as from the utter destruction of their own customers.

Dan Schneider’s story, as harrowing as it is, can be a source of hope with his demonstration that change can be accomplished. Good people can make a difference and Dan Schneider is a living example of that fact.
