What is the penalty for the possession of magic mushrooms?

The punishment is minimum 2-10 yrs state jail, 3rd degree felony. If you are put on probation instead it is 5 yrs. probation. If you violate probation, you will serve a minimum of 2 yrs, no time off for good behavior, etc. I know this is true because my 17 yr old son just did it. He had no priors whatsoever, not even a ticket. On top of that, another person at the scene admitted they were his and not my sons, the cops said they didn't care, it was in my son's vehicle and he got the wrap. While on probation, my son missed a probation meeting because when he called to say he got called in to work, they told him his worker had an emergency and would be out for 2 wks. He thought that meant his meeting was canceled. It wasn't. They issued a felony warrant and he is now waiting for transport to state jail. This all happened in Hays county- San Marcos Tx
