How do you (or do you) explain it to them? I'm not being judgemental, i'm considering both myself, pinning primarily only to avoid liver issues with oral PHs. Not something I'm planning on doing even in 07, probably 08 or later. But I have an 11 year old daughter, and well, drugs are drugs, particularly if I pin. So i'm trying to think through how I would or if I can come up with an answer. Its hard enough to explain the pile of different vitamins/supplements as it is, i'm really unsure how to explain a needle.
