Highest cannabis use found among lower-income, less-educated in new survey

The highest regular cannabis use was found among lower-income, less-educated U.S. adults, according to a Gallup survey released Thursday. 

Gallup defined "regular cannabis use" as using it for a minimum of 10 days per month. Regular usage frequency varied by income and education.

The highest regular use was recorded among U.S. adults who earned less than $24,000 per year — at 16 percent — and those whose completed a high school education or less — at 13 percent — according to Gallup.
