Addiction is a much-maligned, muddy word. Until (ca.) the 18th century, it connoted tendency and drive, rather than (self-) affliction. Opium changed that- reportedly.
Lives described as addiction: to the approval and company of peers, to power and its accumulation, to enjoyment and personal satisfaction (to some people, this may be suffering) and to basics such as air, food, water… and possibly even living. When framed this way, and defined in reference to this word, life suddenly becomes a selfish pursuit in which the living will do anything to get their fix, devoted addicts all.
On that note: Marylin Manson - I Don't Like the Drugs, But the Drugs Like Me.
Also: Addiction is apparently yellow.
