I found it harder to quit as a rollie-smoker myself. My theory is the ritual of rolling up a quick cigarette is just as compelling as the actual smoke. I'd find myself rolling at my desk when in a stressful situation a fair bit.
Vaping just didn't fill that void and I think that's part of the reason I gave up (the other being that I just couldn't find a flavour I actually liked, no matter how close the name of it is to 'golden virginia', it never tasted remotely as close)
