Marijuana Delivery Services Evade Bans on Dispensaries, Spread Across California

A flourishing and unregulated industry of pot delivery services is circumventing bans on storefront dispensaries and bringing medical marijuana directly to Californians' homes.

The exact number of delivery services operating in California is unclear, since the state does not keep a registry of medical marijuana distributors or outlets.

In April, 758 services advertised direct delivery of marijuana to patients on Weedmaps.com, a commercial listing service.
