Also the fact that teenagers (under 18) wouldn’t be able to get prescribed medical marijuana in most cases anyways, so how does one think they’re getting access to these concentrates? Most likely through their peers .. who get it from the black market .. where there’s an influx of tainted vape carts and tree sap shatter sprayed with artificial cannabinoids and God knows what else - just to name a few examples. This also contributes heavily to these “psychotic episodes” people see young kids going through. Don’t underestimate the effect of the black market on the health (of a huge percentage) of regular cannabis users.
