Research: Find out how the Central Hudson test was applied in the following cases:

1. The city of Baltimore passed an ordinance banning billboard advertising of alcoholic beverages and cigarettes near schools and playgrounds.
2. The New York State Liquor Authority banned the Bad Frog Brewery label that showed a frog with the second of its four unwebbed fingers extended in a gesture of insult.
3. Alfred Caronia was a pharmaceutical representative for Xyrem, a drug approved by the FDA for the treatment of a specific subset of people suffering from narcolepsy. Xyrem was required to have a black box on its label, the most serious form of warning. Caronia was taped giving a speech promoting off-label uses for Xyrem, and was convicted of illegal misbranding in a jury trial. He made a First Amendment argument on appeal.
