Ok so I'm fifteen years old, and I am currently in Africa at the moment, Sudan to be specific. And I was given a pill being told it was "candy" by a man (who I don't know) in a raksha (basically like a taxi kinda thing) I'm not sure what it is. It has a smiley face on one side of it, and the number 55 on the other. It is pure white and it has a round shape. Please help me figure out what it is!
