And then I counter argue with "that would be news to former 'lesbian actress' Anne Heche. Seems Ellen's ex-girlfriend managed to quit cold turkey after the breakup" ;-)
Also, there's a big difference between having urges to act on something, and actually doing it. A lot of ex-smokers will tell you they may have quit smoking, but they will always be drawn to cigarettes and if they have one puff, they'd be hooked again.
If they are ‘born that way’, why do they have to recruit?
