BT will probably do whatever it takes to get it banned. According to the link at the below, average tax per pack is $1.45 x47mill. OMG that's a lot of mooola per DAY.
BT will not attempt to ban e-cigarettes. If you think about it, BT controls the largest source of nicotine in the U.S. If e-cigs sales continue to rise, BT simply makes more money selling the nicotine.
BP (Big Pharmaceutical companies) and the government only stand to LOSE if e-cigarette sales continue to rise. BP doesn't control nicotine and if smokers switch to e-cigarettes, they are no longer using ineffective pharma products. BP loses a LOT of revenue. Additionally, BP is trying to get government permission to increase the use times of their products, so they can be touted as an "alternative" to smoking (used long-term rather than as a way to wean off nicotine) and compete against smokeless tobacco products by BT (and e-cigs.). E-cigs will kill that potential market because nicotine users who enjoy a smoking-like experience will choose e-cigarettes over gums, patches and lozenges.
The government is dependent upon huge tobacco tax revenues and will lose a ton of money if people switch to e-cigarettes. Even if the government taxes e-cigarettes, it could take years to get those taxes legally established and they couldn't apply the "sin tax" reason since they know that the sin-tax is applicable for products which are known to cause significant harm and e-cigarettes have not been shown to cause the same harm as cigarettes and most likely never will. So, they'll never get the same kind of taxes from e-cigarettes that they get from tobacco cigarettes.
Additionally, the public health groups fighting e-cigarettes receive funding from the pharmaceutical companies, so they have a vested interest in helping BP sell their products and e-cigarettes are a threat to BP profits.
So, it's not BT we need to worry about. In fact, a tobacco company has already released it's own e-cig.
Our enemies are BP, BP-funded anti-tobacco organizations and our own governments reliant upon tobacco tax dollars.
