Section 29.4 Of Title 1. Of Persons Liable To Punishment For Crime From California Penal Code >> Title 1. >> Part 1.
29.4
. (a) No act committed by a person while in a state of
voluntary intoxication is less criminal by reason of his or her
having been in that condition. Evidence of voluntary intoxication
shall not be admitted to negate the capacity to form any mental
states for the crimes charged, including, but not limited to,
purpose, intent, knowledge, premeditation, deliberation, or malice
aforethought, with which the accused committed the act.
(b) Evidence of voluntary intoxication is admissible solely on the
issue of whether or not the defendant actually formed a required
specific intent, or, when charged with murder, whether the defendant
premeditated, deliberated, or harbored express malice aforethought.
(c) Voluntary intoxication includes the voluntary ingestion,
injection, or taking by any other means of any intoxicating liquor,
drug, or other substance.
