Peter Lewis Bankrolls Marijuana Groups

Clevelander Peter Lewis, Chairman of the Progressive Insurance Corp., is known as a generous donor to the effort to defeat George W. Bush this November, and he also promotes the legalization of marijuana through his contributions to various marijuana advocacy groups. Lewis gave $340,000 to the Marijuana Policy Project, according to records filed with the Internal Revenue Service and made available yesterday.

I don't understand liberals. Through localized bans and high taxes, they try to force people to stop smoking tobacco because of health care costs while at the same time they advocate people smoke marijuana as if it's a better type of smoke in a person's lungs and there are no health care concerns. Can anyone explain this apparent contradiction?
