A study out of the University of California, Davis has provided new insights into how marijuana legalization affects teenagers' perceptions and use of the drug.

Researchers found that among Grade 8 and 10 students in Washington State, marijuana use increased after the drug was legalized. 

Attitudes were also affected. The study's findings showed teenagers were less concerned about the harms associated with marijuana after the law changed.

Results varied among slightly older students. Among Grade 12 students, no shift in attitude or use was reported.

In Colorado, where marijuana was legalized in 2012, the study's results were also different. Researchers found no change in attitude or use of marijuana after legalization — for any age group.

Los Angeles residents awoke Sunday morning to find one of the city’s iconic landmarks had been updated with the changing of the years: the famous Hollywood sign had been modified to read “Hollyweed.”

According to a report from the Los Angeles Police Department, security cameras captured footage of a lone individual dressed in black tactical-style clothing climbing the mountain on which the sign sits. According to Sergeant Guy Juneau, the prankster then scaled the sign and used tarpaulins decorated with a peace symbol and a love heart to change the O’s to E’s.

If you support the legalization of marijuana, 2016 didn't give you much to complain about. Last year, residents in four states approved recreational-marijuana ballot initiatives, doubling the total from the end of 2015, while five new states put medical-cannabis laws on their books. By year's end, 28 states and Washington, D.C., had legalized medical pot.

Two San Francisco Bay area lawmakers are proposing a new law that would make it illegal to smoke marijuana and drive.

In November, California voters decided to legalize recreational marijuana under proportion 64. However, the new law only makes it illegal to have an open container of marijuana in your car. 

Sen.Jerry Hill (D-California) told KGO-TV the current law doesn't go far enough. 

"It didn't say anything about if you were driving and smoking a marijuana cigarette or joint while driving or ingesting a brownie at the same time," Hill said in an interview. 

Senate Bill 65 sponsored by Hill and state representative Evan Low in Silicon Valley could close what they call a loophole, according to KGO-TV. 

Just over half the states in the union (and the District of Columbia) now have some form of decriminalized cannabis. But for medical marijuana patients living in a state not yet on that list, getting the medicine they need often means crossing state lines in violation of federal law. That’s exactly what one GOP lawmaker did to treat his cancer — and he says he’d do it again.

In 2014, CNN found at least 100 families in Colorado who had essentially “fled” there in order to ensure a regular supply of medical marijuana for a sick family member.

The door to legalized marijuana in California cracked ajar in 1996, when voters approved the Compassionate Use Act, which allowed doctors to recommend cannabis to their patients.

In November, the door flew open as voters approved Proposition 64 by a wide margin, a measure that legalizes marijuana for adult recreational use and could herald the beginning of the end of the federal government’s misbegotten war on weed.

Comedian Tommy Chong’s image grinned from a freeway billboard near Sacramento in recent months, promoting the counterculture icon’s brand of marijuana to passing motorists. 

But now a campaign has begun to outlaw such ads from all state highways, threatening to block entrepreneurs taking advantage of newly legalized pot in California from hawking their wares to a captive audience stuck in traffic.

Five state lawmakers have introduced a bill that would bar advertisements for marijuana products and services from all 265 state highways — 15,100 miles of roadway — in an effort to prevent the marketing of pot to minors in the state.

In 2010, when husband and wife team Scott Palmer and Kristi Knoblich were looking for just the right legal marijuana high, they found a real gap in the market. Edibles either tasted bad, were poorly labeled or just didn’t do it for them.

So they decided to make their own.

Noticing that cannabis went especially well with chocolate, the duo worked with a chocolatier to create a “cold water” method that used no butter or any other solvent to create weed chocolates. 

For the duo, who were both cannabis users, or “patients,” as they refer to legal users, it was a turning point. (“Patients” is how brands refer to legal users of medical marijuana who use it to treat ailments from joint pain to anxiety. It also sounds better than “stoners.”)

Thanks to voters who checked “yes” for recreational marijuana legalization on this year’s election ballot, gift-giving during the holidays is about to get a lot more dank. But just because recreational marijuana is legal in a state doesn’t necessarily mean you can just give it away willy nilly. Make sure your holiday good cheer doesn’t come with a side of incarceration by using this handy guide to cannabis gift giving, organized by state.

Puff, Pass & Paint, the nation's first cannabis-friendly art class, adds locations in Las Vegas and California as additional states legalize recreationally.

"Puff, Pass & Paint", the nation's first cannabis-friendly art class, continues to expand nationally with recreational legalization in California, Nevada, Massachusetts, and Maine.
