NEW JERSEY: Even as Americans’ support for legalizing marijuana has doubled, and more than 20 states have loosened marijuana restrictions in various ways, Gallup finds relatively little increase throughout the past three decades in the percentage of U.S. adults who say they have tried marijuana.
Thirty-eight percent of Americans admit to having tried marijuana, compared with 34% in 1999 and 33% in 1985.
he latest results are from Gallup’s annual Consumption Habits poll, conducted July 10-14.
Before Americans’ self-reported experimentation with marijuana leveled off in the 1980s, it surged in the 1970s, rising from 4% in 1969 to 12% in 1973 and 24% in 1977.
Gallup’s trend by age reveals that widespread experimentation with marijuana first occurred among adults aged 18 to 29 between 1969 and 1973, rising from 8% to 35%. It then continued to mount, reaching 56% by 1977, and remained at that level in 1985. Since then, however, marijuana use among young adults has progressively declined. At the same time, as the bulge of young adults who tried marijuana in the 1970s ages and replaces older Americans who never tried it, the rate of all Americans who have ever tried the drug has increased slightly.
