Will the electronic cigarette lead to the demise of cigarette companies?

The electronic cigarette has already begun to cause a bit of a stir amongst smokers.  Many smokers are beginning to share how this device has lightened a heavy feeling in the lungs and returned the senses of smell as well as taste buds.

 The increasing taxes on cigarettes, especially those in New York City have many smokers starting to consider the advantages to switching to electronic cigarettes.

While this device has not been given the official status of a smoking cessation device, many smokers have already used it to quit.

So, what will this mean for the cigarette companies?  And will tobacco growers be forced into finding new uses for the tobacco plant in general?
