How have courts interpreted the terms 'maintaining' or 'opening' in reference to narcotics cases?

"Cases construing the terms 'maintaining' or 'opening' in reference to narcotics cases rely on earlier opinions which construed those terms in statutes proscribing maintaining alcohol-related nuisances during Prohibition. These were places whose proprietors meant them to be used for consumption or sale of alcohol. Similarly, the courts have held that Health and Safety Code section 11366 and its predecessor, section 11557, are aimed at places intended for a continuing course of use or distribution." (People v. Shoals (1992) 8 Cal.App.4th 475, 490; see also People v. Vera (1999) 69 Cal.App.4th 1100, 1102-1103 ["The defendant seems to suggest that a violation of section 11366 occurs if a person engages in the personal, sequential use of any of the specified substances in his or her residence. We do not read this section to cover mere repeated solo use at home. To 'open' means 'to make available for entry' or 'to make accessible for a particular purpose' [citation], and to 'maintain' means 'to continue or persevere in' [citation]. When added to the word 'place,' the opening or maintaining of a place indicates the provision of such locality to others"].)
