The only withdrawal is from nicotine. so just vape more and then leave a mod in his office...

Actually the addiction action with cigarettes is far more complex than just being addicted to Nicotine! There are some MAOIs which add to the action within the human body.
Big Tobacco knows more about the methods and actions of Nicotine Addiction that even Medical Science. That is why it is beyond far more tougher, I know that didn't sound right, for people to stop smoking Analogs vs someone who Picked up Digital Cigarettes from the get go. I know of two friends of mine who never smoked cigarettes but would smoke cigars when they drank when they went out. They picked up electronic cigarettes and just ran with them.
Funny thing about these two is they don't just wake up in the morning and have the first thought across their brain being the fact that they need to smoke or Vape rather! They might go until lunch before they Vape for the first time.
Further, the FDA allows Big Tobacco to add crap to the tobacco before they make their cigarettes. Now what exactly are they adding? No one knows really beyond them and the FDA. Some of these additives may seem to be harmless or added to increase shelf life and flavor, what have you. However they know good and well that they add stuff to increase the addictive potential to this evil, evil drug.
Yes not only are cigarettes addictive on their own like Crack ......., but the FDA allows these companies to increase that addictive potential. All in the name of Big, Big profits. Ultimately its all about money in the USA and the bottom line. And the government allows this to happen just because Republicans are getting the kickbacks from the Lobbyist; well and Dems too. I mean not to draw up party lines here so please just ignore that last statement.
