SECTION 51890-51891
51890. (a) For the purposes of this chapter, "comprehensive health
education programs" are defined as all educational programs offered
in kindergarten and grades 1 to 12, inclusive, in the public school
system, including in-class and out-of-class activities designed to
ensure that:
(1) Pupils will receive instruction to aid them in making
decisions in matters of personal, family, and community health, to
include the following subjects:

(B) Mental and emotional health and development.
(C) Drug use and misuse, including the misuse of tobacco and
alcohol.

Not saying that it's not a giagantic stretch or whether I agree with the approach or not, but this is what they are referencing.
