I've heard it referred to as the "poor man's prozac". Well, maybe not so poor any more, as the price has risen considerably.
The majority of the cost of smokes is taxes, the government is addicted to tobacco tax. Now that the general public has given the government the power to confiscate the property of citizens because they are engaging in a lawful activity, the floodgates have been opened. Every group the government decides to attack after smokers, groups that applauded the attacks on smokers, will say, "But...but...they weren't supposed to do this to meeeeee!"
You reap what you sow.
