Interesting post you have here. Freedom on drugs. This would be a hard topic to discuss because everyone has their own view on how to deal with this.

There's really not any solution. The government will try to regulate what's being sold, like alcohol or tobacco. However I know people who are under 21 that can always get alcohol. Not hard.
Harder drugs are heavily illegal here, but I think I have heard that in other countries where drugs like this are deemed legal, but frowned upon. Those countries have a much lower death rate than the US in drug overdoses.

Maybe if we give all humans the freedom to be in control of their own body, they will realize that they need to take care of themselves better.
