Gallup reports the percentage adults in the U.S. who say they smoke marijuana has more than doubled since 2013.

Gallup has tracked marijuana use for more than a decade. The latest data released this month shows:

  • Marijuana use has risen from 7% of U.S. adults in 2013 to 15% in 2024.
  • Men are more likely than women to say they smoke marijuana.
  • Democrats (23%) are more than twice as likely as Republicans (10%) to report using marijuana.
  • Regionally, the highest rates of marijuana usage are in the West (19%), Midwest (16%) and East (16%). Marijuana use is lower in the South, where 11% report using it.

The increase in marijuana use is troubling, given how research continues to show that marijuana is both addictive and harmful.

A study published in JAMA Otolaryngology found daily marijuana use is linked to a higher risk of head and neck cancers.

Marijuana can damage adolescent brains — resulting in permanent loss in IQ, difficulty thinking and problem-solving, reduced coordination, and increased risk of psychosis.

A large study published in February found marijuana use is associated with increased risk of cardiovascular problemsAnother study published last year found heavy users faced about 60% higher risk of heart attack, stroke, or other cardiovascular problems.

The list goes on.

As marijuana use increases in America, people need to understand: Marijuana may be many things, but “harmless” simply is not one of them.
