Peter Reuter, a professor at the University of Maryland, told Bloomberg:

It's all about distribution costs. Being closer to the producer lowers costs.

Philip J. Cook, professor at the Sanford School of Public Policy at Duke University, said:

Illegal drugs prices will of course have a premium that reflects local zeal for enforcement.

The same can be said for the heavily taxed legal commodities, since the street price may be dominated by smuggled goods.
