Health - K & Addiction potential

[schwing]

I just remembered that my ex-girlfriend's (who I never see anymore) imaginary friend's dying wish was to know why there seems to be a large discrepancy in reports of K's addiction potential. According to Erowid "Ketamine has the potential to be both physically and psychologically addicting" but doesn't list symptoms of physical dependencies. Any SWIY out there who can shed some light into this?

Also, he was wondering if anyone could tell him SWIY's predisposition to addiction in general, addiction level to K (i.e. high, med, low-none), and what other substances SWIY may be addicted to (this is all hypothetical of course).

For example, Balthazog (which was his name) in general seems to have a low-ish predisposition to become an addict. He enjoys alcohol, occasional brownie and at other times a trip out into other dimensions, but never craves for any of those things. He'll admit that he's addicted to tobacco but even then never needs more than 5-6 cigs a day. At the same time, he'll never try heroin or crack because he doesn't want to deal with expensive addictions and associated risks to health.
