Substance abuse is a prevalent issue among college students, with many reporting alcohol and marijuana dependency. The college environment can be a significant factor, as it is a time of self-discovery, newfound freedom, and increased academic pressure. Alcohol and marijuana are the most frequently initiated and used substances by college students, with approximately 14% meeting the criteria for alcohol use disorder and 20% reporting monthly marijuana use. Binge drinking is also common, leading to negative consequences such as poor academic performance, physical injuries, sexual assaults, and mental health issues. Fraternity and sorority members exhibit higher rates of substance use and are more susceptible to developing alcohol use disorders later in life. Understanding and addressing substance abuse among college students is crucial to mitigate its adverse effects on their health, academics, and overall well-being.

Alcohol and marijuana are the most frequently initiated substances by college students
According to the National Institute on Alcohol Abuse and Alcoholism (NIAAA), alcohol is the most widely used substance among college students in the United States, with approximately 64% reporting lifetime use. Binge drinking, defined as consuming five drinks or more for males and four drinks or more for females on one occasion, is also prevalent, with 39-49.6% of full-time students engaging in it. Binge drinking is associated with various negative consequences, including a higher risk of unintentional injuries, sexual assault, and poor academic performance. Approximately 1,519 to 1,825 college students aged 18 to 24 die annually from alcohol-related unintentional injuries, and 696,000 students in the same age group experience assault by another drunk student. Additionally, about one in four students report academic difficulties due to drinking.
Marijuana is the second most commonly used substance among college students. In 2023, around 39.5% of college students used marijuana, and nearly one-fourth of students reported using it within the past thirty days. The percentage of daily marijuana users among college students has increased over the years, with approximately 12% of users reporting daily or near-daily use in the past three months as of fall 2023. The rise in marijuana use is concerning, given its negative impact on memory and learning, which can lead to poor academic outcomes.
While the use of other substances, such as hallucinogens, cocaine, and prescription stimulants, is also prevalent among college students, alcohol and marijuana remain the most frequently initiated substances. The high rates of substance use among college students have significant implications for their health, academics, and overall well-being.

Binge drinking is common among college students, with negative consequences
Binge drinking is a significant issue among college students, with far-reaching negative consequences. The college environment can play a significant role in encouraging heavy drinking. The availability of alcohol at social events and sporting activities, unstructured time, widespread access to alcohol, limited adult supervision, and peer pressure all contribute to the prevalence of binge drinking on college campuses.
According to the National Survey on Drug Use and Health (NSDUH), 49.6% of full-time college students aged 18 to 25 drank alcohol in the past month, and 29.3% engaged in binge drinking. Binge drinking is defined as consuming five drinks or more for males and four drinks or more for females in about two hours. This behaviour can lead to serious health and safety risks, including drunk driving, sexual assaults, and injuries.
The negative consequences of binge drinking among college students extend beyond immediate health risks. About one in four college students experience academic difficulties due to drinking, such as missing classes, falling behind in schoolwork, and performing poorly on tests and projects. Binge drinking can also lead to long-term organ damage, including the liver, and can even result in alcohol-related deaths.
Additionally, social influences play a significant role in binge drinking among college students. Factors such as having alcoholic parents, participating in Greek life, peer pressure, and using other substances like cigarettes and marijuana are associated with a higher risk of binge drinking. However, certain protective factors can reduce the likelihood of negative consequences, such as having close friends who encourage safe drinking practices and drinking in locations that provide food and water.
The high-risk period for binge drinking among college students is during the first six weeks of their freshman year, when they are most vulnerable to peer pressure and the desire to fit in. It is important for students to be aware of the potential consequences of binge drinking and to track their alcohol consumption to avoid harmful levels.

Marijuana use among college students has increased, impacting academic performance
Marijuana use is common among college students in the United States, with around 39.5% of college students using marijuana in 2023. The nationwide prevalence of cannabis use among young adults (ages 19-30) reached a new high in 2021, with 42.6% reporting past-year cannabis use. This increase in marijuana use among college students has had a significant impact on their academic performance.
Research has consistently linked marijuana use to lower GPAs among college students, with one study finding that increasing marijuana use over time was associated with a drop in GPA. Students who used marijuana more frequently during their first year of college took longer to graduate due to lower baseline GPAs resulting from skipping classes. This relationship between marijuana use and academic performance may be explained by the negative impact of marijuana on brain development, cognition, memory, and executive functioning. Long-term, heavy marijuana use has been associated with long-term changes in brain structure, including the hippocampus, prefrontal cortex, and amygdala, which can lead to impairments in information processing, IQ, memory, and neurocognitive performance.
Additionally, marijuana use can contribute to a culture of delinquency and educational disengagement, further impacting academic performance. The normalization of marijuana use through legislative actions and the relaxation of legal penalties may also play a role in the increasing prevalence of marijuana abuse and dependence among college students.
The impact of marijuana use on academic performance is particularly notable when combined with alcohol consumption. Studies have found that the simultaneous use of cannabis and alcohol is associated with lower GPAs, suggesting that cannabis may have a more detrimental effect on academic performance than alcohol alone.
The rise in marijuana use among college students highlights the importance of early intervention and support to address substance use disorders and improve academic outcomes. Addressing the underlying factors that contribute to marijuana use, such as stress and anxiety, can also play a crucial role in mitigating its impact on academic performance.

Fraternity and sorority members have higher rates of substance use and abuse
Alcohol and drug use on college campuses is a well-known phenomenon, with many students experimenting with substances for the first time. While this is a concern across all colleges, fraternity and sorority members have been found to have higher rates of substance use and abuse.
Fraternity and Sorority Members and Substance Use
Fraternities and sororities are social organizations that offer a sense of community and networking opportunities to their members. However, they have also gained a reputation for wild parties and dangerous hazing rituals, which often involve alcohol and drugs. A national fraternity of 3,400 members reported that 97% drank alcohol regularly, and 64% identified as binge drinkers. Binge drinking is defined as consuming five drinks or more on one occasion for males and four drinks or more for females. This behavior contributes to accidents, sexual assaults, emergency room visits, and even deaths on college campuses.
Factors Contributing to Substance Use in Greek Life
Several factors contribute to the high rates of substance use and abuse among fraternity and sorority members. One factor is peer pressure, which is already prevalent in college life and intensified in Greek organizations. New members may feel a strong desire to fit in with their peers, leading to a higher likelihood of substance use. The leaders of these organizations are often upperclassmen who are still young and may encourage or turn a blind eye to such activities. Additionally, the college subculture that promotes substance use is strongest among male members living in fraternity houses.
Long-Term Effects and Treatment Options
The consequences of substance use can extend beyond college. National longitudinal data show that male fraternity members who resided in fraternity houses during college had the highest levels of binge drinking and marijuana use, which continued through age 35. At age 35, 45% of residential fraternity members reported symptoms of Alcohol Use Disorder (AUD), with odds higher than all other college and non-college groups except non-residential fraternity members. Residential sorority members also had higher odds of AUD symptoms at age 35 compared to their non-college female peers.
Recognizing the high risk of substance abuse among fraternity and sorority members, some colleges offer Collegiate Recovery Programs (CRPs). These programs provide students in recovery with sober living communities and the opportunity to thrive in a substance-free environment.

College students with mental health issues are at risk of drug and alcohol abuse
College is a time of self-discovery, independence, and new experiences. However, the pressure of expectations, academic challenges, and social anxiety can make these years incredibly stressful for students. Many turn to substances like alcohol and marijuana as a coping mechanism, which can lead to substance use disorders and negatively impact their mental health.
According to various sources, alcohol and marijuana are the most commonly used substances by college students. In 2023, around 64% of college students reported drinking alcohol at some point, with 29.3% to 39% engaging in binge drinking in the past month. Alcohol overdose can lead to brain damage or death, and it is a significant risk factor for binge drinking. Binge drinking is associated with an increased risk of illicit drug use and negative consequences such as driving under the influence, physical injury, memory loss, and unprotected sex. Approximately 1 in 4 college students experience academic difficulties due to drinking, and it is linked to a higher risk of sexual assault on campus.
Marijuana use is also prevalent among college students, with around 39.5% reporting use in 2023. The percentage of daily marijuana users has increased over the years, with nearly one-fourth of students reporting recent use in 2023. Marijuana use can negatively impact memory and learning, contributing to poor academic outcomes. Additionally, the use of other drugs, such as hallucinogens, cocaine, and prescription stimulants, is also present on college campuses.
The combination of substance use and mental health issues can be detrimental. Approximately 37% of alcohol abusers and 53% of drug abusers among college students also struggle with serious mental illnesses. While many students with mental health issues felt the need to reduce their substance use, only a small percentage received treatment for both issues concurrently. The stress and expectations of college life can trigger or exacerbate existing mental health difficulties, and substance use can further complicate their recovery.
It is important to address substance use disorders and provide support for students struggling with mental health issues. Resources such as counseling programs, medical leaves of absence, and modified study programs can help students during and after their treatment journey. By recognizing the risks associated with substance use and mental health issues, we can empower students to seek help and make healthier choices.
