There's a lot of confusion about what is and isn't legal -- especially among teenagers and people who recently moved to Washington or Oregon. First, smoking pot is still illegal in public or if you're under age. But adults are allowed to have in their possession one ounce or less.

But how much is an ounce? Honestly, I couldn't tell you. And the Portland police department found a lot of people honestly couldn't tell you. So they came up with a fun way to educate the public: compare it to a doughnut!

Below you can see a pile of weed next to a doughnut for size comparison! I'm still surprised how much space an ounce takes up. I guess it doesn't weigh a lot.
