The tablet is a Canadian "222" made by Johnson & Johnson - Merck Consumer. The pill contains 375 mg aspirin, 30 mg (or 15 mg) caffeine and 8 mg codeine phosphate. It's an over-the-counter medication in Canada.
I'm not sure about the amount of caffeine. Two databases (one governmental) say 30 mg and another source says 15 mg. And a quick internet search brought up online pharmacies who state it's 15 mg caffeine.
