Hello. I found some capsules in my kids room that I need help identifying. The first is a solid black capsule with the word ICE written on the side of it. The second is a yellow capsule with black strips on one side and ys224 over 3850 on the side of it, and the third is a light blue six-sided pill with stamina on one side and RX on the other. I think I already know the last two from looking on this website, but I cannot find anything on the black one, so please help. Are they dangerous or illegal? Or should I not worry too much about them? Thanks.
