A Florida man who won a contest to watch the series finale of Breaking Bad with the cast has been charged with running a drug distribution operation.

The Lee County Sheriff’s Office says Ryan Lee Carroll sold synthetic marijuana and shipped it across the US from his home with two other men.

He was arrested on New Year’s Eve.

Authorities seized more than $US1 million ($A1.1 million) in synthetic marijuana during a bust.

According to deputies, the suspects used a cement mixer to create the drugs. The drugs were shipped through the US Postal Service.

Investigators also seized a souvenir Hazmat suit signed by Breaking Bad cast members.

The TV show follows a former teacher who produces and sells methamphetamine with a former student.
