LOS ANGELES — A Southern California man who smuggled $11 million worth of erectile dysfunction drugs into the U.S. from China has been sentenced to more than eight years in federal prison for conspiracy and smuggling contraband.

Prosecutors say the drugs sold by 41-year-old John Lee of Walnut were dangerous black-market creations falsely advertised as herbal remedies and some customers suffered permanent injuries.

Lee also was ordered Monday to pay $550,000 in restitution to victims.

Prosecutors say from 2011 to 2017, Lee illegally imported powdered tadalafil — the active ingredient in the prescription drug Cialis.

Lee made 5 ½ million pills, some containing 14 times the level of the drug found in Cialis.

He pleaded guilty in February. More than a dozen other associates and companies have pleaded guilty to conspiring with Lee.
