A bunch of generic Concerta drugs were removed from the market awhile back and several more sprung up. They’re nowhere near the same and the quality is garbage. I was on one in college while on state insurance. They use some older release mechanism from like the 80s using a pinhole on one side and half of my true generic pills didn’t even have a visible hole. I ended up in the ER because one released all at once at like 7pm, and I thought I was dying due to excessive adrenaline.
