First time I tried to crush a concerta pill it took half an hour and I crushed the push layer which doesn’t have any MPH so it was all a mess. I have generic concerta, they are round and say TL 709, first you need to put the pill standing up so like on it’s thin side sorry I can’t really explain good, and then you take something sharp, razor blades work best cause they’re thin, put the razor exactly în the middle of the thin side then apply pressure and it will cut very easily the you throw away the dark green part, but don’t throw away the pink coating that’s on the green part, you can hold the green part in ur mouth until the pink/brown coating dissolves and eat it, then you can throw the green part away and just crush the white part you’re left with easily!

I hope this helped
