Ausable amount is a quantity that is enough to be used by someone as a

controlled substance (he/she) possessed.]
[Two or more people may possess something at the same time.]
[A person does not have to actually hold or touch something, to possess

Defenses - Instructional Duty
The prescription defense is codified in Health and Safety Code sections 11350 and
11377. It is not available as a defense to possession of all controlled substances. The
defendant need only raise a reasonable doubt about whether his or her possession of
the drug was lawful because of a valid prescription. (See People v. Mower (2002)
28 Cal.4th 457, 479 [122 Cal.Rptr.2d 326, 49 P.3d 1067].) If there is sufficient
