My question involves criminal law for the state of: California

So after discussing my use of medical marijuana with my probation officer she told me that because recently the County Probation Department has realized how easy it is to obtain a physicians recommendation for the use of medicinal cannabis they have decided to not recognize any physicians recommendations. According to SB 420 and People V. Tilehkooh I should be in the clear but she says that they will only accept "prescriptions for medical marijuana use from the county health board". Can she do that or not?

According to SB 420, a recommendation is valid if it is issued by an "Attending Physician", which is an individual who possesses a license in good standing to practice medicine or osteopathy issued by the Medical Board of California or the Osteopathic Medical Board of California. Any physician who satisfies this criterion may issue a valid recommendation.

Whether the county probation department is willing to recognize it or not I have according to SB 420 and the compassionate use act of 1996 a valid recommendation.

So my question is am I in the clear?
