A Psychologist I've been seeing says that the psychological component of smoking...the hand to mouth thing...the social thing which isn't as huge now as it was when i started smoking...is actually more powerful than the nicotine alone. and he has the letters PhD after his name which makes me think he has SOME idea about this...(not really sure tho cuz those letters mean little anymore LOL)
Sorry the reply is so late, I've just started reading this
thread. But I can't pass this one up without a reply. Yes, the psychological components of the addiction (and there are several) are much more powerful than the physiological part. And really, that's one of the reasons that the PV is SO MUCH MORE EFFECTIVE than patches, gums, or any other method of consuming nicotine, when you want an alternative to smoking. It effectively mimics the actions and sensations associated with the addiction. "The hand to mouth thing" is commonly referenced as the most powerful part, but misses the mark.
The "hand to mouth thing" is an association with a thing learned early in childhood. By observing adults surrounding you, you learned that you can grab a thing with your hand, and you can transport it to your mouth. At that point you can consume it and it is UNDENIABLY YOURS!!! No one can take it away from you. Mostly it's a learned association with ownership and loss prevention. And yes, that's a pretty influential lesson in today's world.
But if you think about the very first thing you ate as an infant, It came from either a breast or a bottle. And who taught you how perform that action? NOBODY. The source of that knowledge was genetics and it is "hardwired" into what is referred to as the "primitive brain".
More on the act of "sucking". Whether it's a bottle, a breast, a thumb, or a "binky", it has a nurturing, and calming effect on infants. It's also a critical component of the infant's relationship with its mother, which of course is the foundational basis for developing all future interpersonal relationships as well. With that thought in mind, consider the importance of interpersonal relationships in our species...
Then consider the act of "sucking" on a cigarette, pipe, or pv... and the relationships between nurturing, calming, building interpersonal relationships, and satisfying an addiction. The "hand to mouth thing" doesn't seem to be quite as influential anymore, does it?
