What about them?
Are you saying, "we need a centralized national govt telling us what we can do as opposed to defending our rights"?
Is there something in the constitution that gives congress the authority to do this?
Who sets this standard? The federal govt, or 50 independent states?
So many questions.
Prohibition gave birth, and feed drug cartels.
We no longer have an alcohol prohibition.
If you have something that disputes the studies done on teenagers and alcohol use, I would love to see it.
People don't like to feel bad and if they are unable to deal with the "bad" feelings, then they try to find ways to escape that feeling.
Some look for things that exhilirate them by skydiving, racing, etc; whereas others look for "chemical" escapes.
Teenages generally have a harder time dealing with the day to day stress and are more prone to go for the chemical escapes, whether it's alcohol, meth, downers, paint, mj, etc.
Unfortunetly; all this does is mask the feelings and when they "come down", the problems are still there.
This results in some people beginning a cycle, where eventually they end up "escaping" all the time and teenagers have a higher percentage of falling into the trap of addiction. Whether the addiction is physical or psychological.
It's been shown that the majority of teenagers haven't developed the coping skills to deal with these things and while the age of 21 may seem to be just picked out of a hat, studies have shown that normally around the age of 21(not all the time) changes in their behavior and lives tend to keep them more centered.
There's more involved, then just this quick post; but I'm not sure that anyone is going to accept more information, if they're going to automatically dismiss what has already been determined.
