Cocaine is catching the attention of police.
In 2013, Roanoke City dealt with seven deadly cocaine overdoses, the most in the Commonwealth.
Statewide, 134 deaths were linked to cocaine overdoses last year, nearly 50 percent more than 2010.
"The problem is driven by demand," said Assistant U.S. Attorney Don Wolthuis, whose office focuses on the Western District of Virginia. "Only if we can try to limit demand or prevent people from becoming addicted or get people who are addicted to seek some sort of treatment can we reduce the problem."
While cocaine continues to be a problem, investigators are also looking closely at heroin as well.
Coming up Thursday on WSLS 10 at 6 p.m., we examine heroin overdoses in Southwest Virginia and why there's light at the end of the tunnel for addicts.
