At the stroke of midnight on July 1, recreational marijuana became legal in the state of Oregon. Thanks to Measure 91, passed by voters last November, the Beaver State now joins Washington, Colorado, Alaska and the District of Columbia as the only U.S. jurisdictions where cannabis users can toke up freely.

Here are your top questions about this new development, answered.

Dude! So, like, how legal is legal?
Oregon has, arguably, the least restrictive regime in the county. At home, Oregonians can keep up to eight ounces — that's half a pound! — of pot. It's also now legal to grow up to four mature plants per residence. But be careful: Out on the streets, the legal limit in your pocket is only one ounce.

Smoke filled the air at the Burnside Bridge in downtown Portland last night as marijuana smokers lit their celebratory joints, marking Oregon’s legalization of recreational use.

Oregon’s marijuana supporters have been waiting for this moment since last November, when voters backed Measure 91, a law that allows for recreational use, Reuters reported.

WILLIAMS, Ore. — Forty-two years after Oregon became the first state to decriminalize small amounts of marijuana, the state is taking its first steps along a road leading to state-licensed stores selling limited amounts of it to anyone over 21.

"Oregon has long been a pioneer on sensible marijuana policies," said Anthony Johnson, chief petitioner on Measure 91, which on Wednesday makes Oregon the fourth state to adopt laws legalizing recreational use of cannabis for people old enough to drink.

He added though that he doesn't expect much increased demand for it.

Smoking it in public is illegal, but in Portland police are discouraging residents from calling 911 to report smokers.

Yep, you read that right. The Oregonian/OregonLive is taking a stab at growing its own weed.

We've got two seeds (Blackdog variety) and two clones, or starter plants (Dogwalker OG variety). Enough to max out the four-plant limit per household Oregonians 21 and over are allowed. Plus, the bonus of a passionate cannabis gardener and weed science-geek, Jeremy Plumb, to help get us started. He serves on four cannabis-related boards and is the founding member of Farma cannabis dispensary at SE 9th and Hawthorne.

Who's growing it?

PORTLAND, Ore. — Oregon began easing into an era of legal marijuana Wednesday after an early morning pot celebration at the center of Portland.

A few thousand people jammed a sidewalk and bike lane on the Burnside Bridge at midnight Tuesday and counted down the moments until July 1. That's the date voters established for adults to be able to legally possess and grow limited amounts of marijuana for personal use.

With the vote last fall, the state became the fourth with legal pot, after Colorado, Washington and Alaska. More than 40 years earlier, Oregon was the first state to decriminalize small amounts of pot.

"Oregon has long been a pioneer on sensible marijuana policies," said Anthony Johnson, chief petitioner on Measure 91, the legalization initiative.

WILLIAMS, Ore. –  On the third Thursday of each month, veteran medical marijuana growers and hopeful newbies gather in the old Williams Grange hall in a small rural Oregon valley long known for growing some of the best cannabis on the planet.

Since voters last fall made the state the fourth to legalize recreational marijuana, people have been flocking to the hall to get the latest update on lawmakers' progress on crafting rules for the new industry.

The entrepreneurs also share tips on how to produce happy and healthy marijuana plants.

"Why not come to the source to learn about growing?" says Gina Erdmann, director of the Oregon SunGrown Growers' Guild, as she lays out materials on the sign-in table outside the hall, now a community center.

BEND, OR / ACCESSWIRE / July 1, 2015 / Med-Cannabis Pharma, Inc. (MCPI) is pleased to announce the completed deal to create a high quality grow facility in the state of Oregon. In the last quarter of 2014, MCPI embarked on a new Joint Venture with Royal Tree Organics to begin a new premier medical marijuana grow facility to produce and bring high quality medicine to market. With 2 MCPI dispensaries already operating in the state of Oregon and the expansion of 2 more dispensaries underway, the impact and importance of this Joint Venture grow facility cannot be overstated.

Kalyx Development pays $3 million for complex that previously was water bottling plant

A west Eugene factory that once produced computer hard drives and later bottled water could next become an industrial-scale marijuana growing operation.

The Eugene Water & Electric Board on Friday sold the 107,000-square-foot building at 3590 W. Third Ave. for $3 million, according to a deed filed with Lane County on Friday.

The buyer is Kalyx Develop­ment, a New York City-based marijuana real estate firm.

Kalyx bills itself online as “the premier real estate development provider to emerging indoor agricultural operators on the national level.”

Recreational marijuana is legal in Oregon starting today. And with it comes a host of new business opportunities.

But it's not just people growing and selling pot who are preparing to cash in.

Marijuana is not like other cash crops. People don't typically raid wheat fields or break into grain bins. But Noah Stokes of CannaGuard Security in Portland said the high value of pot makes it a frequent theft target.

Stokes said the underground nature of the marijuana business has meant many growers haven't invested in state-of-the-art security systems.
