An NBC News writer has revealed how his father lead a secret life as a millionaire drug dealer before he blew it all – ending up a penniless sanitation worker.

Tony Dokoupil has told how his father Anthony ran one of the biggest marijuana operations in the last century with a lavish life that was straight of the gangster epic Scarface.

Anthony made the equivalent of $6 million during his career and but did not tell his young son who only found out the truth when he was 20.
