Yes, but I think you are exaggerating the need for the nicotine, it's the routine that is addictive more than anything. The nicotine effect is so small that it can easily be removed from vaping if the user wants. So getting back to the topic of the thread, there is nothing to worry about in regards to a non smoker using an e-cig with nicotine because the nicotine isn't addictive enough to make them want to do it.
That's a big gamble you're taking there. We're not able to predict how an individual will react to any potentially addictive substance. Most "addicts" are the minority of a given population (of folks who "try" something or other even over a period of time). I knew a guy who did opiates, liked them, did them a lot, and walked away when he got older. According to the drug warriors, that isn't supposed to happen. But it does. With any and all street drugs.
We don't yet know how addictive anything will be for a particular individual until they show up addicted. Only then can we say, "yeah, that stuff us addictive for you". Eventually we may understand our biology well enough to do individual prediction but at this point can only talk odds from population studies.
And given that 0 nic is as readily available as liquids with nic, why take the risk your individual genetics and biology predispose you to a nicotine addiction?
