New 2024 NIDA Statistics on Cannabis Use and Mental Health

A Growing Concern

The latest data from the National Institute on Drug Abuse (NIDA) paints a concerning picture about cannabis use and mental health risks, especially among young adults.

According to their 2024 study, a staggering 15% of schizophrenia cases in men aged 16-49 in 2021 may have been avoided by preventing cannabis use.

Marijuana’s Mental Impact

The findings align with a growing body of research linking marijuana use in young adults to serious mental health conditions like schizophrenia and bipolar disorder. Teens who use cannabis regularly are also more likely to experience depression, anxiety, and social withdrawal.

The Numbers Don’t Lie

  • NIDA reports a 7% increase in cannabis use disorder cases among 18-25 year olds from 2020 to 2021.
  • Alarmingly, the percentage of adolescents aged 12-17 who perceive no risk from smoking marijuana once or twice a week has doubled in the past decade.
  • Young adults who used marijuana before age 18 were 2-4 times more likely to develop schizophrenia or other psychotic disorders later in life.

Major depression affects a substantial portion of the U.S. population, with an estimated 21.0 million adults experiencing at least one major depressive episode, representing 8.3% of all U.S. adults. The prevalence is notably higher among females (10.3%) compared to males (6.2%). Adolescents are also significantly impacted, with 20.1% of those aged 12 to 17 experiencing major depressive episodes, and the rate is higher among females (29.2%) compared to males (11.5%).Source

States with the highest rate of marijuana use

Vermont leads the nation with the highest rate of marijuana use, with just over 22% of people aged 12 and up reporting use in the last month. Recreational marijuana has been legal in Vermont since 2020.

Alaska, Colorado, Oregon, and Maine round out the top five states for marijuana usage. Recreational marijuana has been legal in Alaska and Oregon since 2014, in Colorado since 2012, and in Maine since 2016.

Oklahoma has the highest rate of marijuana usage (16.61%) among states where recreational use is currently not legal.

As cannabis legalization spreads, experts urge heightened caution and education about its potential mental health risks, especially for developing brains. Early intervention and prevention could mitigate potentially life-altering consequences. With more research underway, 2024 may mark a turning point in understanding marijuana's complex effects.

Higher THC Levels Linked to Increased Risk of Developing Schizophrenia

As cannabis strains become more potent, with higher levels of the psychoactive compound THC, new research points to an alarming trend. Studies show that frequent use of high-THC cannabis may significantly increase your risk of developing schizophrenia and other psychotic disorders.

Weed and Mental Health - Understanding the Link

Cannabis use, especially strains with high THC content, can act as an environmental trigger for schizophrenia in those genetically predisposed. THC can disrupt normal brain development and function, potentially leading to psychosis.

Can weed cause schizophrenia?

The Evidence

A landmark study published in The Lancet Psychiatry analyzed data from over 900 individuals, including cannabis users and non-users. The findings were clear - those who used high-potency cannabis had a significantly higher risk of developing a psychotic disorder compared to non-users.

"We demonstrate that acute administration of THC induces significant increases in positive, negative, general, and total symptoms with large effect sizes in adults with no history of psychotic or other major psychiatric disorders. Notably, effect sizes were greater for positive symptoms than for negative symptoms but not for general symptoms, indicating that THC induces positive symptoms to a greater extent than negative symptoms. This result is consistent with findings that symptom severity is greater for positive than negative symptoms in cannabis users."


Another study in The American Journal of Psychiatry found that daily cannabis use, particularly of high-THC strains, increased the risk of psychotic-like experiences also known as weed psychosis by up to 159% compared to infrequent or no use.


Starting cannabis use at a younger age appears to amplify the risks associated with its consumption. Research indicates that the adolescent brain, which is still in a critical phase of development, is more susceptible to the negative impacts of cannabis (National Institute on Drug Abuse). Early use can interfere with cognitive functions such as memory, attention, and decision-making (American Psychological Association). Moreover, the likelihood of developing dependency increases when cannabis use begins during adolescence rather than adulthood (National Center for Biotechnology Information). Delaying cannabis use until adulthood, when the brain has fully developed, is crucial to mitigating these risks and ensuring better long-term mental and physical health outcomes.

Overview of Youth Mental Health Statistics from 2024

Alarming Rise in Mental Health Issues

According to the latest statistics from the National Institute on Drug Abuse (NIDA), the mental health crisis among youth continues to escalate at an alarming rate. In 2024, a staggering 18% of adolescents and 23% of young adults reported experiencing mental health concerns - a significant increase from previous years.

Major Depression and Suicidal Ideation

The data reveals that 5% of youth are grappling with severe major depression, a debilitating condition that can severely impact their daily lives and overall well-being. Even more concerning, 12% of youth have reported serious thoughts of suicide, highlighting the urgent need for accessible and effective mental health support services.

Early Intervention is Crucial

Mental health experts emphasize the importance of early intervention and preventative measures to address this growing crisis. By identifying and supporting at-risk individuals early on, we can potentially mitigate the long-term consequences of untreated mental health conditions. Comprehensive strategies that address the root causes, such as trauma, stress, and substance abuse, are essential in tackling this multifaceted issue.

A Call for Collective Action

These alarming statistics serve as a wake-up call for communities, policymakers, and healthcare professionals to prioritize youth mental health. Increased funding for research, education, and accessible mental health services is crucial in reversing this trend. Additionally, destigmatizing mental health and promoting open dialogues can create a supportive environment where young individuals feel empowered to seek help without fear or shame.

Protecting Teen Mental Health: Avoiding Early Cannabis Use

The Vulnerable Adolescent Brain

During adolescence, the brain undergoes critical development and maturation processes. This delicate period sets the stage for emotional regulation, decision-making abilities, and overall cognitive functioning. However, early and regular cannabis use can disrupt these intricate processes, potentially leading to long-lasting consequences on mental health.

Heightened Risk of Psychosis

Adolescents who use cannabis regularly are more susceptible to experiencing psychotic symptoms, including hallucinations, delusions, and disordered thinking patterns. These symptoms can persist and worsen over time, significantly impacting an individual's ability to function in daily life.

Impaired Cognitive Development

Beyond the risk of psychosis, early cannabis use has been associated with impairments in cognitive development. Regular use during adolescence may adversely affect attention, memory, problem-solving skills, and overall academic performance. These deficits can have far-reaching consequences, hindering personal and professional growth in adulthood.

Protecting Mental Well-being

To safeguard teen mental health, it is crucial to prioritize prevention and education efforts. Parents, educators, and healthcare professionals should engage in open and honest conversations about the potential risks of early cannabis use. Providing accurate information and fostering a supportive environment can empower teens to make informed decisions and seek help when needed.

Additionally, addressing underlying factors that may contribute to substance use, such as mental health issues, peer pressure, or family dynamics, is essential. By offering comprehensive support systems and promoting healthy coping mechanisms, we can help protect the mental well-being of our youth and ensure their successful transition into adulthood.


The 2024 statistics on cannabis use and mental health in youth are a call to action. This data shows increased schizophrenia risk that demands a response. While some seek to legalize cannabis, its mental health impact on developing brains cannot be ignored.
