Comments:US researchers increase tobacco's oil production for biofuel use

Wasteful exercise
The stated goal of developing plants for biofuels that are not food crops is of questionable value. If there is enough land it doesn't matter what crops we use as long as we are using the land efficiently. If using non-food crops means less biofuel production, then we're wasting land by not using the optimum biofuel crops. This research appears to be a wasteful exercise in genetic engineering without any real benefit to alternative energy production.

Second hand exhaust
As if tobacco smoke from people wasn't bad enough, now it'll be coming from cars?

Well, the Oil dosent contain Nicotine, as far as I am aware. would still smell like i though 164.116.47.180 (talk) 15:58, 15 January 2010 (UTC)

The spanish team referred in the article is, in fact, working to obtain bioethanol from Prickly Pear and from Tree Tobacco (Nicotiana glauca), wich is a shrubby plant, and - certainly - not the same as common tobacco (Nicotiana tabacum)
