Nearly half of Americans say they’ve tried cannabis at least once, according to the latest figures from Gallup.

In the research firm’s July 5-9 poll on Americans’ consumption habits, 45 percent of respondents copped to cannabis use - a new high in Gallup's trend.

When Gallup first asked this question in 1969, a mere four percent of respondents said they’d tried cannabis. This increase mirrors the rising support for cannabis legalization. Last year, a record 60 percent of respondents said cannabis should be legalized.

In this latest poll, 12 percent of Americans said they currently smoke cannabis – nearly twice the amount to say so in 2013.

The survey found that young adults, men and those with annual household incomes of less than $30,000 are most likely to say they currently consume cannabis. When broken down by sex, 13 percent of men said they smoked cannabis compared to seven percent of women. Eighteen percent of those between 18 and 29 and 13 percent in the lowest income bracket reported smoking cannabis.

In terms of age demographics, those aged 30 to 49 are most likely to have tried cannabis (51 percent), followed by those from 50 to 64 (49 percent.)

“If more states legalize the drug, regular usage – or at least experimenting with marijuana – could rise,” writes Gallup.

“Legality may confer a certain societal acceptance of the drug. [Attorney General Jeff] Sessions' hopes to prosecute state-level marijuana crimes may prove to be a hindrance, but it is unlikely this multibillion-dollar industry will be stopped anytime soon.”
