The anti-drug police are taking actions to show that marijuana is not legal yet.
Although President Laura Chinchilla is urging the decriminalization of some drug use, there has been no firm decision. Much of the discussion will take place at a future meeting of heads of state.
So the Policía de Control de Drogas conducted raids early Thursday and made arrests in Osa, Jacó and Montes de Oca.
