Study: Adult use of certain substances continues to rise

A record 44% of adults aged 19-30 and 28% of adults aged 35-50 reported using marijuana last year, the National Institutes of Health reported today. An estimated 8% of adults aged 19-30 and 4% of adults aged 35-50 reported using hallucinogens, up from 3% and 1%, respectively, a decade ago. Among other findings from the annual Monitoring the Future survey, alcohol use increased 2% over the past five years in adults aged 19-30 and 2% over 10 years in adults aged 35-50. Use of cigarettes, sedatives and non-medical opioids declined for both age groups over the past 10 years, while amphetamine use declined for 19-30 year olds but increased for 35-50 year olds.
