Fentanyl is worrisome, especially as it can easily contaminate other things, but also lol cops!
These aren’t made to look like candy, unless you count mommies Oxycodone as candy. Round shape with an M inside a box on one side, a score mark with 30 on the other in light blue is a type of Oxy according to the pill database. Whoever made these has a similar die press but seems to have run out of blue so went for all the colors instead, at least it’s a nice way of marking most but not all of them as certainly not Oxy.
