Youth use of pot and cannabis-abuse treatment did not increase after Washington’s legalization of marijuana for grown-ups, according to analysis by a state think tank. But more study is required before more sweeping conclusions can be made.
Youth use of pot and cannabis-abuse treatment admissions have not increased in Washington since marijuana was legalized, according to a new analysis by the state Legislature’s think tank.
Under Initiative 502, the state’s legal-pot law, the Washington State Institute for Public Policy (WSIPP) is required to conduct periodic cost-benefit analyses of legalization on issues ranging from drugged-driving to prenatal use of marijuana.
One of those reports was due Friday after three years of legal sales. But the report was limited in scope to just a few impacts — including the degree of youth use and adult use, treatment admissions and criminal convictions.
“In my overall appraisal, there’s not much evidence I-502 has caused changes in the outcomes we looked at,” said Adam Darnell, the lead researcher and author of the WSIPP report. One exception is that researchers found adults consumed more pot in parts of the state with higher per capita sales, Darnell said.

The findings represent a “snapshot of our progress to date and are an intermediate step towards the ultimate cost-benefit analysis of I-502,” the report states. “Results may change as implementation of the law progresses and more outcome data become available.”
The report arrives shortly after U.S. Attorney General Jeff Sessions criticized implementation of legal pot in Washington. Sessions’ critique was panned by Gov. Jay Inslee and state Attorney General Bob Ferguson, who said it was based on outdated information and faulty conclusions. Inslee and Ferguson have said they want to meet with Sessions to help him understand Washington regulations and safeguards.
The think tank also has published details about jobs and wages in the legal pot industry that were separate from the analysis published Friday.
At the end of last year, the industry accounted for the equivalent of 6,227 full-time jobs, according to WSIPP, whose mission is to provide nonpartisan practical research. Wages paid from 2014, when the first businesses were licensed, through 2016 totaled $286 million.
The average hourly wage stood at $16.45 but that was elevated by a few highly paid workers, researchers said. The median wage was $13.44. Licensed pot businesses averaged nine full-time employees.
The think tank’s findings on youth use were not surprising as they were based on a biannual survey by the state Department of Health of students in the sixth, eighth, 10th and 12th grades released earlier this year.
Pot use by students in all four grade levels was stable or has fallen slightly since I-502 was enacted, the WSIPP report said.
For instance, 17 percent of the 10,835 high-school sophomores surveyed last year said they consumed pot in the previous month. The level was 18 percent in 2006 and 20 percent in 2010.
Legalization was approved by Washington voters in November 2012. Legal sales began in July 2014.
As for adult use, people living in counties with higher levels of legal sales were more likely to consume pot and do so more frequently, based on state telephone surveys, the report said.
“It’s not earth-shattering that people were using more of a product they’re buying more of,” Darnell said.
While researchers were comfortable reporting that relationship, they did not provide details on those higher levels because they want more data before doing so.
On cannabis abuse, researchers found that admissions for publicly funded treatment fell in the three years after I-502 was enacted. Admissions dropped from 7,843 in 2012 to 6,142 in 2015.
There is no evidence, the report said, that legalization caused the decline. Without more data “we don’t know if the decline would be greater” if pot remained illegal, Darnell said.
In another unsurprising finding, misdemeanor convictions for pot possession by adults dropped sharply after legalization, according to the report.
Prohibitions for minors did not change under I-502; possession remained illegal for them. But convictions began to decline in 2012, dropping from 1,015 at the start of the year to 722 in early 2013. The report did not ascertain why.
“Overall, these analyses should be considered preliminary,” the report concludes. Future reports will include additional findings and come closer to a cost-benefit evaluation.
