Medicine: Vaccine for Nicotine?

Today, a Swiss pharmaceutical company is set to unveil the results of a study for a new nicotine vaccine. The vaccine, which sensitizes the immune system to protein-complexed nicotine, allows a person's body to attack free nicotine in the blood stream. This apparently prevents any ingested or inhaled nicotine from entering the brain and causing addiction.

If this stuff works, it really will open up a whole can of worms for society. While undoubtably people who want to quit smoking will benefit from the vaccine, who else should be receiving it? Should parents give it to their kids? What does this do to the concept of free choice? Or maybe this will encourage people to try smoking because now they're not worried about being addicted to it. Very interesting indeed.
