Would federal legalization affect state laws?

Only partly. Removing cannabis from the federal Controlled Substances Act would end federal prohibition, but it would not repeal, replace, or override state cannabis laws. States would keep the power to legalize, ban, license, tax, and restrict cannabis inside their borders.

A state like Idaho or Wyoming could still prohibit sales in a fully legal federal market, while a legal state could keep its own rules on possession limits, advertising, and retail licensing.

Why state laws would survive federal legalization

States hold broad police power over health, safety, and commerce within their borders. Federal law overrides state law only when Congress says so clearly or when the two directly conflict.

Courts apply the same logic to alcohol. The 21st Amendment gives states wide authority over alcohol sales, so a dry county can stay dry even though alcohol is federally legal nationwide.

Hemp is the closest cannabis example. The 2018 Farm Bill legalized hemp at the federal level, and several states still banned or tightly restricted it anyway.

What federal legalization would actually change

Does federal law override state cannabis bans?

Usually no, unless Congress writes a preemption clause that says so. A legalization bill that simply removes cannabis from the CSA schedules leaves state bans in place.

The sharper conflict is interstate shipping. The Dormant Commerce Clause blocks states from discriminating against out-of-state businesses, so a state ban on imported cannabis could face a serious legal challenge if federal law allowed cross-border sales.

Would states have to honor another state's legal weed?

No. Legalization is state by state, and no state is required to accept products or licenses from another. Federal rules and interstate compacts would decide shipping, not reciprocity between states.

What this means if you buy weed online

State law, not federal law, decides whether an online order or delivery is legal where you live. Even after federal legalization, an online retailer could ship only into states that permit it.

Check three things: your state's adult-use or medical status, whether licensed delivery is allowed, and whether the seller holds a state license. Federal legalization would widen the market, but it would not make purchases legal in states that still ban cannabis.

Would federal legalization make weed legal in every state?

No. It would remove federal penalties, not state ones. Prohibition states could keep enforcing their own bans, and you would still face state charges there.
