I suggest everyone take a minute to read up on addiction studies by a guy named Bruce Alexander. 

The right sees it a moral failing and the left sees it as a person's brain getting hijacked, but both sides have it wrong. Bruce says it’s not your morality and it’s not your brain. To a much larger degree than we’ve ever before appreciated, it’s your cage. Addiction is an adaption to your environment.

Treatment won't help anything because addiction isn't an individual disorder, it is a societal problem. 

The people banging junk into their arms, sleeping in homeless camps or swilling cheap vodka in the alleyways of Anchorage, somehow, someway need to be plugged back into society.

SB91, in my view, is putting the cart before the horse. They should have established treatment centers for these people prior to just letting them all out of jail. Everyone I know that didn't like this bill said the same thing... there is no treatment options included.
