If I am 19 and live in Washington State and I buy liquor in BC will border control confiscate it because it's in my vehicle Or will they not search or not confiscate it?

If you are 19 and purchase liquor in British Columbia, you could face issues at the Washington state border, as the legal drinking age is 21 in the U.S. Border control has the authority to search your vehicle, and if they find alcohol that you are not legally allowed to possess, they may confiscate it. It's advisable to check the specific laws and regulations before attempting to bring liquor across the border.
