I am a pharmacist at a local Pharmacy, and a worried mother came to me asking me about a certain pill she found in her sons room. He has recently been caught with marijuana, and she is seriously worried about him. So she brought me the pill and asked me what it was. The problem is, i have no idea. It is small, round, quite flat. I cracked it open to see the inside, and its black. Any idea what it could be?
