@Hiding: nicotine is considered the most addictive of all drugs (yes, doctors consider it more addictive than even ......). So, health arguments aside, I would never, ever give something so powerful to a child who is still barely learning how to delay gratification. That's just setting them up for a lifelong battle of dependency. Kids are already way overstimulated as it is. The last thing they need is another stimulant in their mind/body.
