Are you fucking retarded...? Please don't ever have kids. This logic doesn't even apply to adults.

It's a similar principle of good sexual education. Kids want to do what other kids are doing, so we might as well teach them everything they need to know about it and allow them to do it safely. Not tell them weed will ruin their lives and cocaine gives you heart attacks. If you think literally lying to kids and instilling fear in their hearts is a good way to stop them from doing something, you're an asshole. If you think we're going to stop people, let alone kids, from using and abusing drugs out right because we tell them it's bad, well, the facts speak for themselves don't they.
