JACKIE CHAN'S SON DETAINED FOR DRUG CHARGES.

The case has proved embarrassing for Jackie, who is an antinarcotics ambassador

Kung-fu movie star Jackie Chan’s son, Jaycee, was sentenced to six months in prison on Friday after pleading guilty to marijuana-related charges in a Beijing court.

The court convicted Jaycee, 32, of providing a venue for marijuana use and also fined him the equivalent of $326, the state-run Xinhua News reported.

The young actor and singer was arrested in August along with Taiwanese actor Ko Chen-tung, and both men admitted to smoking weed themselves.

The case has proved an embarrassment for his father Jackie, who in 2009 was made an antinarcotics spokesman by the Chinese police.
