first of all, i was kidding when i said you must have smoked too much weed if you thought that addictive personalities don't exist.

and so what if upbringing/attitudes play a part in addictive personalities? umm that's kind of the point... psychologists know that. just like any personality trait, you can be born with an affinity toward acting a certain way, but events in your life (or your upbringing) can enhance the trait or make it less apparent. this does not mean that addictive personalities don't exist...
