Half of males (50%) and more than half of females (59%) in federal prison were serving time for drug offenses on September 30, 2014.[1]

How many started that way or their crime involved weapons/money that were involved in a drug operation? How many repeat or lifetime criminals were first created with a non-violent drug crime?
If it is non-violent it should not be something that locks you up ever as that is cruel and unusual punishment, outside the law that is abduction and locking them up in a box.
Jailing non-violent offenses costs the taxpayer and the individual more to no benefit. There should be payment penalties and temporary records for those that do repeat offenses, real rehabilitation, mental help, also job programs for them if desired. All of that would probably be cheaper than creating lifetime criminals.
Not just for non-violent drug offenses, when I hear about people stealing cars for instance and getting locked up it makes no sense. Insurance exists, and we want the criminal out working to pay that back not debt taxpayers 30k+ per year, it is a loss all around and compounding.
