Trazodone is not a controlled substance.
Now, if this kid was stealing this much medication, you would have thought that the stepdad would have gotton suspicious as to why his 1 month supply was disappearing so fast each month. I think the parents are a little clueless, more so when they're drugged, apparently.
See my post #27; the pills are so cheap doctors will prescribe gigantic amounts just to save the patient some money (If your pharmacy's going to charge you $10 to fill a script for 1 pill or 300, you might as well go for the 300). So I can see how the kid could conceivably siphon off a large amount of the medication. But yeah, the parents have got to be clueless anyway. Like I posted way up top, the stuff tastes nasty, and you'd have to be a little off to wonder why everything you eat and drink suddenly tastes like those icky pills your doctor gave you.
