Which Penal Code section addresses "possession of controlled substances"?

Penal Code Section 11350 focuses specifically on the unlawful possession of controlled substances in California. It outlines the legal parameters defining possession and the penalties associated with this offense, which includes drugs classified under specific schedules that are deemed illegal without a prescription.

This section is essential for law enforcement officers as it provides the basis for arrest and prosecution related to drug possession offenses. It differentiates between various types of substances and articulates the requirements for proving possession, including actual control over the substance or constructive possession, where an individual has access to a controlled substance even if it is not in their immediate control.

The other provided references relate to different issues. For instance, Section 12021 deals with prohibited persons possessing firearms, while Section 11357 addresses possession of less serious offenses specifically related to marijuana. Section 1203.07 refers to probation terms for certain offenses, notably in context to cases that can involve possession but do not directly focus on the controlled substances themselves.
