What is the difference between a charge of attempted possession of cocaine and battery?

(1) People v. Boyd (1985) 167 Cal.App.3d 36, 47, 212 Cal.Rptr. 873: "Attempted possession of cocaine is not closely related to the charge of armed robbery. The societal interest in proscribing robbery--security of personal property from a felonious taking--has no relationship to the societal interest in proscribing the possession of narcotics--elimination of a dangerous substance the use of which represents a serious risk to the health and welfare of the appellant and perhaps others who might come into unlawful possession thereof."

(2) People v. Santos (1990) 222 Cal.App.3d 723, 739-740, 271 Cal.Rptr. 811: "The crimes charged and battery protect the same societal interest--the security of the person."
