Is cannabis legal under U.S. federal law?

No. Under the CSA, cannabis remains a Schedule I substance federally. State or territory programs do not change federal prohibitions, especially on federal property and in interstate/international transport.

Can I fly with cannabis within the U.S.?

Airports and air travel involve federal jurisdiction. Do not transport cannabis in air travel even if endpoints have legal programs.

Why do states look similar in shorthand but differ in practice?

Program details vary—possession limits, home-grow rules, expungement, licensing, product types, and DUIC standards. Always check your state's official portal.
