Is possession of cocaine base a necessarily included or necessarily included offense of possession of methamphetamine?

Here, based on the same evidence, the jury convicted defendant of both possession of cocaine base and possession of that same cocaine base for sale. Possession of the cocaine base is a necessarily included offense of possession of that same substance for sale. (See People v. Oldham (2000) 81 Cal.App.4th 1, 16 [holding the offense of possession of methamphetamine "is necessarily included in the greater offense of possessing the same substance for sale based on the same evidence"].) Accordingly, we reverse defendant's conviction for possession of cocaine base.
