CVHS Kids Smoking Pot During Breaks

Although my mom lives in CV, I don't but I go see her daily. Neighbors have been complaining about increased highschoolers use of weed during breaks and so far - despite calling the sheriff's office - nothing happens. Is the CVHS principal aware of this, the teachers, local politicians, the school district, their parents? If you need to be 21 to buy at a dispensary, where are these kids getting their hands on weed and how? Does anybody care?
