London, Jan 10 (IANS) Rapper Snoop Dogg has reportedly been detained for carrying small amount of cannabis in his tour bus, but later he was released.

The 40-year-old, who has been jailed on numerous occasions over drug and firearm possession charges in the past, had his tour bus stopped by law enforcement officers at a border patrol checkpoint in Sierra Blanca, Texas, over the weekend, reports tmz.com.
