PORTLAND, Ore. (AP) — Discounts on pot, free food for folks with the munchies and live music. All part of a historic day for Oregon and for marijuana advocates across the country, as recreational sales of the drug begin today.

Oregon is one of four states that have legalized the sale of recreational marijuana.

It already has more dispensaries than Washington state, where pot shops have been up and running for more than a year.

Pot shops in Oregon that already sell medical marijuana have made big plans for today — and hope there is enough supply to meet what is expected to be a huge demand.

Until January, sales will even be tax free — a savings of up to 20 percent.

Some dispensaries opened just after midnight to get a head start on sales.
