As far as a genetic component.....keep believing it, but it ain't true. They searched and searched, but can't find an addiction gene. It must be hiding right next to the elusive gay gene. All humans have propensities to addiction, some folks more than others of course. Our nurturing (upbringing) exacerbates that propensity. Some folks obsess over neatness, money, etc....others become workaholics, etc....the true "well balanced" individual is likely addicted to moderation!!
The other problem with chemical addictions is that that they do produce physical, not just mental addiction. They are a class above activity related addictions/obsessions......though some of those can be downright deadlyas well.
The disease nomenclature does raise eyebrows in some circles. However,seeing as how it is definitely an affliction, has mental and physical symproms manifest, and can be overcome/controlled through a proper treatment regimen.....the definition does fit.
Lots of words, sorry, worked all day now I am relaxing. The "higher power" very much does have a place in treatment, who else can help you overcome what has you licked besides a higher power?
Anyways....I transitioned from drugs to alcohol at 15 since alcohol was legal (sort of) and cops would never bust a teen with booze...pour out maybe.
Took me 26 years of trying my best to "be respectable" to admit my own defeat in that department. 10/23/2005 is the day I hope to never forget.
Since then I have also given up the nicotine habit (couple years back)...and worked off some of the extra pounds those chocolate fixes were putting on. Life is good.
