Sounds like it could be an Ecstacy pill. Because those pills have odd shapes and intricit designs on them. But go here..

There is a list of the pills or medications that might match your description. Your description is very short but I
think that it could possibly be Ecstasy.
But if it is, please tell your friend's mother to don't put him in the dog house. Tell her to confront him and ask him why. In a low soft voice. And tell him all the reasons that any pill can be dangerous. Especially Ecstacy. Just don't be rational. And let him tell you. If he doesn't ask him where it could of come from then. And follow the questions and awnsers.
