According to an article in Medical News Today, marijuana use increased and the drug's perceived harmfulness decreased among eighth- and 10th-graders in Washington after marijuana was legalized for recreational use by adults.
But there was no change among 12th-graders or among students in the three grades in Colorado after legalization for adults there, according to a new study published online by JAMA Pediatrics.
Washington and Colorado became the first two states to legalize recreational use of marijuana for adults in 2012, followed by handful of other states since. The potential effect of legalizing marijuana for recreational use has been a topic of considerable debate.
According to research findings, no changes were seen in perceived harmfulness or marijuana use among Washington 12th-grades or students in the three grades in Colorado, for which researchers offer several explanations in their article.
Sales of legal marijuana jumped 17 percent to reach $5.4 billion last year, according to a new report.
Sales could grow 25 percent this year, to $6.7 billion, according to the marijuana industry investment and research firm ArcView Market Research.
By 2020, sales of legal marijuana could reach $21.8 billion, Fortune reports.
“I think that we are going to see in 2016 this next wave of investors, the next wave of business operators, and people who’ve sort of been watching or dipping their toe in, really starting to swing for the fences and take it really seriously,” ArcView CEO Troy Dayton said.
The report includes medical and recreational dispensary sales, as well as cannabis products sold through delivery services and medical marijuana “caregivers” who can legally grow and distribute the drug.
The increase in sales coincided with the first full year of recreational marijuana sales in Washington state, the article notes....
Does legal marijuana tempt pot users to consume more alcohol -- or are they likely to opt for cannabis instead of chardonnay?
A University of Washington team of researchers sought to address those questions in the context of evolving marijuana policies in the United States.
Their findings, published online Dec. 21 in the journal Alcoholism: Clinical & Experimental Research, highlight the difficulties of gauging the impact of a formerly illicit drug as it moves into the mainstream
Recreational marijuana use is now legal in four states and medical marijuana in 23 states. Research on legalization policies has focused largely on how they impact marijuana access and use. But the UW team wanted to know how legalization affects the use of alcohol, by far the nation's most popular drug.
The majority of adults in the U.S. imbibe to varying degrees, and alcohol abuse is the third leading preventable cause of death nationwide....
