It will still be illegal to smoke marijuana in public places, such as a Bumbershoot concert, on a downtown street corner, or in a public park. In fact, think of it like an open container of alcohol -- anywhere you can't drink, you can't smoke marijuana either.
"So, the idea of someone smoking in public, they shouldn't be doing it, and if we deal with them they could get a ticket," said Seattle police spokesman Sean Whitcomb.
But Whitcomb says it's not something officers are going to be looking for.
"In fact, the joke might be that if we see someone smoking a joint on one corner, and someone drinking a beer on the other corner, we're going to go after the beer drinker," Whitcomb said. "Marijuana is still our lowest priority by city ordinance."
In the privacy of your home, of course, you will be able to use marijuana. But not if you live on the University of Washington campus.
"What would happen is that it would put at risk a lot of federal funding that we receive," said Norm Arkans, a University of Washington spokesman.
"We get a lot of research funding, our students receive federal Pell grants, we are obligated under the federal law to ensure that there are no drugs on campus."
That's because marijuana is still illegal at the federal level, and so like the UW, no dope smoking at Seattle's North, South, and Central Community Colleges.
"Since the federal law is in effect, we are going to adhere to the federal law," said Paul Kilpatrick, president of Seattle Central Community College.
He says there hasn't been any push back or feedback from the students yet. "But I'm sure I'll hear about it later," he said.
And while smoking marijuana will soon be legal and purchasing it will be legal, selling it will not. Which creates a certain conundrum.
The Seattle Police Department is updating the "frequently asked questions" section of their website and they'll post that in the next couple days.
