Some research indicates tobacco could be useful as a biofuel by altering it's genes. You might approach the issue by stating that tobacco farmers and economies have been hard hit by less demand for their product by lower use, higher taxes, social stigma, etc.. and that by finding ways to use it as a biofuel will generate income for those reliant on it's production, decrease reliance on oil imports, it's not a food crop, etc.. Compare costs of production versus benefits of oil production from tobacco bio-fuel.
"Tobacco, a crop under siege as the number of smoking bans in the United States continues to increase, may be turning a new leaf as a possible source of home insulation and biofuel.
At Thomas Jefferson University in Philadelphia, researchers at its Biotechnology Foundation Laboratories have figured out how to tweak the genes in tobacco plants to increase their oil production, which could help spur their use as biofuel.
"Tobacco is very attractive as a biofuel because the idea is to use plants that aren't used in food production," said study co-author Vyacheslav Andrianov, assistant professor of cancer biology at Jefferson Medical College. He added:
We have found ways to genetically engineer the plants so that their leaves express more oil. In some instances, the modified plants produced 20-fold more oil in the leaves...
Based on these data, tobacco represents an attractive and promising 'energy plant' platform, and could also serve as a model for the utilization of other high-biomass plants for biofuel production.
The preliminary research has been published online in Plant Biotechnology Journal."

"Some researchers say an age-old cash crop long the focus of public health debate could be used to help solve the nation's energy crisis, by genetically modifying the tobacco leaf for use as a biofuel.
The golden leaf is the latest in a series of possible biofuels like switchgrass and algae that are being floated as Congress and President Barack Obama stress the importance of securing alternative energy sources.
Scientists believe using tobacco would be beneficial because it would not affect a major U.S. food source, unlike other biofuels made from corn, soybeans and other crops.
But there's no worry here about second-hand smoke for commuters stuck in traffic: the tobacco wouldn't be burned to power vehicles, merely used to extract its oils and sugars.
Attractive option
Tobacco is an attractive "energy plant" because it can generate a large amount of oil and sugar more efficiently than other crops, said Vyacheslav Andrianov, a researcher at the Biotechnology Foundation Laboratories at Thomas Jefferson University in Philadelphia.
Andrianov recently co-wrote a paper on how researchers have found a way to genetically engineer tobacco to boost the oil in the plant's leaves. Researchers found that modifying the plant produced as much as 20 times more oil, according to the report published online in December and featured in a special biofuels edition of the Plant Biotechnology Journal."
