@daringfireball the idea is good, mainly because banning something people are addicted to leads to a huge black market, fueling organized crime.
By excluding those who never got into the habit, chances are this will lead to at least a significant drop in smokers.
Best of all: if they succeed, in thirty years we’ll have a generation of non-addict politicians banning the use for all, including the original authors of the bill. They’ll be pissed, but karma comes around. ‘tis a filthy habit anyway.
