A new analysis is putting a sharper spotlight on cannabis use among parents, and the numbers are hard to ignore. The study points to a rise that stretches across several demographics, while also raising fresh questions about child safety, household exposure, and the growing comfort many adults seem to have with marijuana.
Researchers found that cannabis use climbed noticeably among parents from 2012 to 2024, with daily use showing up far more often than daily drinking. By the end of the study period, an estimated 5.9 million U.S. children were living with a parent who used marijuana on most days, a figure that adds weight to concerns about what happens when use becomes part of the home routine.
In 2024, 8% of parents used cannabis on most days, 5.2% used it daily, and 6.7% met the criteria for cannabis use disorder. Daily marijuana use among parents was about four times as common as daily alcohol use, a contrast that stood out in the findings and helped frame the broader shift in adult behavior.
The increase was not spread evenly across the board. Researchers saw especially large jumps among younger parents, unmarried parents, lower-income households, and those without a four-year college degree, suggesting the trend is tied to more than simple culture or changing laws.
The data came from the National Survey on Drug Use and Health, which included nearly 482,000 Americans age 12 and older. The work was published in the journal Addictive Behaviors, adding another layer of research to an issue that has quickly moved from the margins into everyday life.
Doctors say the biggest mistake is assuming legal automatically means harmless. One family medicine and addiction specialist warned that marijuana has become so socially acceptable that people are starting to miss the risks, especially when it comes to how often it is used and who is around it.
That concern gets louder when children are in the picture. If marijuana use is a regular part of life at home, kids may start to view it as normal, and studies suggest children whose parents use marijuana are more likely to use it later themselves, even if that connection does not prove direct cause and effect.
THC, the main psychoactive compound in cannabis, can affect attention, memory, coordination, and reaction time. For a parent, that matters in a very practical way, because children need quick responses, clear judgment, and steady supervision during the thousands of small moments that make up daily life.
Edibles bring another layer of risk that is easy to overlook. Gummies, chocolates, and other products can look a lot like candy, and doctors say accidental ingestion has led to more emergency room visits involving children who consumed marijuana by mistake.
Some of those cases can get serious fast. Children may experience severe sedation, confusion, trouble walking, or even breathing problems, and hospital care may be needed when the dose is high enough or the child is especially sensitive.
There is also the issue of secondhand smoke, which remains part of the conversation even when marijuana use happens outdoors or near open windows. Marijuana smoke contains many of the same harmful chemicals found in tobacco smoke, and children can still be exposed to THC through the air.
Frequent use can also slide into dependence without much warning. The more often marijuana is used, the greater the risk of cannabis use disorder, and high-potency products may raise the odds of psychiatric problems in vulnerable people, especially when use becomes regular instead of occasional.
The researchers were careful to note the study’s limits. It did not measure parenting quality or children’s health outcomes, and it cannot prove that parental cannabis use causes harm, but it does point to a pattern worth paying attention to.
Because the survey relied on self-reported use, the results may also be affected by memory or reporting bias. Even so, the findings raise important questions about household habits, storage practices, and what children are absorbing long before they are old enough to understand the difference between a habit and a hazard.
For parents who use marijuana every day, the toughest question may be the simplest one: can a day go by without it? That answer can say a lot about whether use is staying in the background or quietly taking center stage at home.
