I hear you on that on hit.
When you get down to it, no amount of regulation can keep anything out of the hands of people/kids. I know I'm not the only one that managed to get my first cigarettes and alcohol at 15-16 years old. Hell, illegal drugs were just made lucrative by outlawing them.
Money spent writing/enforcing laws should be put toward education in my opinion. That's the only way to really combat their use.
