I should have been clearer - lots of people given medical opiates DO go on to be dependent, especially if they're prescribed in a home setting.
Sadly, the "associative cue-response" aspect of addictive drugs is not understood by most prescribers. I think almost all smokers understand it, intuitively at least - "coffee and cigarettes", "post-coital cigarettes" etc etc
Yes indeed... sometimes at sundown... my stupid brain STILL pines for a beer, almost 23 yrs without one. There's just something about that time of day... and all those Happy Hours I attended...
And recently I was such in a foul mood from a long tiring horrible day, I was yelling and kicking stuff and said I WANT A DRINK! Fortunately my husband knew I was talking out of my nethermost orifice.
