I wonder where that BS article came from? For someone who owns/runs a treatment center they don't seem to know much about burenorphine which is MUCH less likely to interfere with day to day functioning.
Also, kids who find bupe aren't going to put them under their tongue They will either swallow them whole ir chew them, meaning very, very poor bioavailability.
ANd in the US, EVERY SINGLE WEEK a toddler finds their parents' gun and kills someone, usually thinking they are playing with a toy. That ain't happening with Subs or 'done I promise you.
