Drugs are not a tool?
They don't make people kill or hurt others.
Neither do drugs.
Crystal Meth obviously does.
If you can demonstrate evidence to me, of Crystal Meth jumping out of a baggie, and committing a murder, I'll buy your argument.... otherwise, I'll afford it as much credence as I afford the arguments of anti-gun activists who insist that guns commit murders... (which is to say none)
Drunk driving is illegal.
But alcohol is not.... see the distinction?
