With more and more states legalizing marijuana, whether for medical use, recreational use, or both, increasing numbers of Americans are using cannabis. A new survey finds that one in seven had used marijuana in 2017, with smoking being the most common manner of consumption, according to a report published in the Annals of Internal Medicine.

People were more likely to vape or to consume marijuana as an edible in states where recreational use has been legalized, researchers found in the nationally representative survey of 16,280 U.S. adults.

Overall, 14.6 percent said they had used cannabis in the past year, while 8.7 percent said they had used the drug in the past 30 days. A greater proportion of people, 20 percent, reported using marijuana in the past year if they lived in a state where recreational use was legal, as compared to just 12 percent in states where it was completely illegal. In states where medical marijuana was legal, 14 percent of those surveyed said they had used in the past year.

While 12.9 percent reported smoking marijuana, 6 percent said they had consumed edibles, 4.7 percent reported vaping, 1.9 percent said they had used concentrates and 0.8 percent reported using topical versions of cannabis. [Read more at Reuters]
