"Behavior"?
Shouldn't the word be "consequences"?
Yes. Actions have consequences. It's something they don't teach much anymore.
Deal with the consequences when someone's action causes harm. Teach that, and teach good behavior so that people know HOW to act as a mature and responsible adult. If you don't act responsibly, you will suffer consequences.
I assume most of us here want a smaller government footprint, and a fiscally responsible government that isn't into every facet of our lives. I do not like government programs that exist to save me from myself - or to inflict restrictions on me because of something somebody else did.
Train children and adults to be responsible for their behavior and to think of the possible consequences of their possible actions - before they make a big mistake. Our popular culture and even our government often promotes bad behavior with little or no consequences (sometimes even rewards!).
On the scientific side, am I wrong in thinking that pot is a fat soluble substance that resides in the fatty organs, whereas alcohol is water based and pees out? Pot shows up longer in a blood test than alcohol does because it takes longer to metabolize the fat. It doesn't necessarily mean that you are impaired, but you could be.
People that want smaller government need to think about less regulations and laws. Period. Make sure that actions have consequences and let everybody else live their life.
