which government branch deals with the medicinal marijuana issue?

Answer 1

The State Legislature. Inasmuch as the U.S. Supreme Court cannot declare a state law unconstitutional because such a law is not even in the U.S. Constitution.

The tenth Amendment of the U.S. Constitution states," The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people."

Answer 2

All of them. "Deals with" is way to broad a term.

At the federal level, Congress has outlawed marijuana for any purpose under federal drug laws. Federal law enforcement (executive branch) is responsible for enforcing federal laws.

Federal judges are supposed to apply federal laws. So the recent federal judge that said marijuana is illegal was correct. He was applying the laws as Congress has mandated them.

Some states have allowed medical marijuana, but state laws are overridden by federal laws, per the Supremacy clause of the Constitution. So, until Congress removes the restriction, or makes an explicit exception in the case of state legislation, it falls on Congress.

Answer 3

The Judicial branch.
Despite many states having passed medicinal marijuana and decriminalization laws, the Supreme Court declared that these laws were unconstitutional.
That's the end of the story.
