what is the difference between state law and federal law when it comes to drinking?

There is no federal law that covers legal drinking age. States are allowed to create their own law.

However, they do have strong persuasive powers, such as in 1984 when they threatened to withhold federal highway funds from any state that did not raise the drinking age to 21. And again recently when they wanted states to lower the legal limit to .08 for drunk driving. All the states complied with both requests.

There is no federal law on the issue other than some requirements to keep highway funds that states had to lower the max blood alcohol level to 0.08% and raise the drinking age to 21. As well as some tax law.

Drinking laws are all state laws.

For almost all laws, state law will be same as federal law.

Dont rember what it is called, but the state law may differ from Fed law under some sort of title.

because State and Federal rules shop on with to diverse circumstances. most of the conflicts ensue at the same time as the federal authorities interferes in concerns that are, lower than the structure, State concerns.
