For a country that prides itself on freedom and fairness, why create a system that punishes for doing what they want with their body? What if we spent the billions we do now on a failed drug war for education, addiction treatment, mental health, job training? Why ban certain drugs and allow alcohol and cigarettes that have just as addictive properties and kills just as many people?
It's not right, its not fair, and until the judicial industrial complex (private prisons, police forces & civil forfeiture used for revenue instead of proper tax increases) is dismantled, we'll continue to see these sorts of travesties.
We have a lot of cruft to cut from the US legal system.
