Los Angeles County's district attorney says he intends to prosecute owners of marijuana dispensaries that take cash for pot.

District Attorney Steve Cooley said Tuesday he believes state law only permits the possession, use and cultivation of medical pot — not sales.

Most dispensaries currently sell pot to those with doctor referrals and identification cards. Some patients grow pot and distribute it through the shops.

Cooley's statement came after a pair of committees rejected City Attorney Carmen Trutanich's proposal to ban sales of marijuana at dispensaries as part of an ordinance that could be voted on by the City Council on Wednesday.

In 1996, California voters approved a measure that allows medical use of pot.
