Clean by David Sheff. the author is a jounalist who's sun was once addicted to meth. He takes a look at decrimnilizing addiction. Since additction itself is rarely looked alone as a stand alone pathos, this is an important tome. A lot of the time we look at addiction and its negative or acceptable pull on us based on what we are addicted to. Addiction to aclohol, shameful. Additction to pizza, tolerable. Perhaps addiction itself is worth examining.
