Key Points

  • College students can be more prone to experimenting with substances.
  • They often use stimulants to enhance experiences, or depressants to relax.
  • Regular use can lead to addiction. Fortunately, help is available.

College is where you start new things—new classes, new friendships, new relationships, new jobs, and, for some, drugs and addiction. Many young adults experiment with substances in high school or college, which can lead to more intense use in college; potentially, addiction.

College students tend to use drugs most accessible to them. We’ll cover the 7 most common drugs used in college, emerging trends, and how students can find treatment.

Alcohol: The Top Contender

Alcohol ranks #1 as the top-used drug in college1, with well over half of students reporting they drink. It’s easily accessible, cheap, and found outside class in most (if not all) social settings. College parties and campus Greek culture notoriously include alcohol, often consumed in excess by students with a low tolerance. 

Parties are a regular part of college culture, occurring on game days, weekends, and… spontaneously. Roommates may drink together on non-party days or go to bars after class. Alcohol is seen as celebratory and a catalyst for meeting friends and garnering social connections. Many students struggle to avoid it, even if they’d like to or hadn’t planned on making alcohol a cornerstone of their college experience.

Regular use and binge drinking can lead to addiction and other adverse health effects.

Marijuana: The Most Prevalent Recreational Drug

College students might turn to alcohol for a night out with friends or use marijuana to relax and unwind. Much like alcohol, marijuana is readily accessible on most campuses, regardless of its legal status in the state.

Students may smoke weed to relax after class, to socialize with peers, or because they feel an intense urge to take it. This often signifies an addiction.

Weed use can be more challenging to conceal, since it leaves a distinct odor.

Prescription Pills: A Double-Edged Sword

When used as prescribed, prescription pills can help students navigate chronic pain and mental health conditions like attention deficit hyperactivity disorder (ADHD). College students can also use these medications recreationally.

Use of Prescription Painkillers

Doctors often prescribe opioids for severe pain, typically after a surgery or for conditions like cancer. As an opioid, these medications can also trigger a flood of dopamine2 and sense of wellbeing (especially when not used as prescribed), which reinforces the action. Some college students seek out this effect even after their prescription runs out, or they’re no longer in pain.

Illegal opioids can contain fentanyl, which is a synthetic opioid 50x stronger than heroin3. More college campuses are including Naloxone kits to help students reverse an overdose to opioids or fentanyl. But the best way to avoid the risk is only taking prescribed medications as prescribed.

Study Drugs

A grade can determine a lot—if you get accepted into a competitive program, if you meet requirements for a scholarship, and the quality of future jobs. Many college students also want good grades for their own sense of accomplishment. Achieving A after A isn’t easy, which is why some college students (around 4%) reach for study drugs.

Study drugs are prescription stimulants used to improve focus and energy4, theoretically. Not all cases of taking a stimulant imply this, though. Study drugs include4

  • Adderall 
  • Ritalin 
  • Desoxyn

A student taking one of these medications would likely have a prescription. It becomes a study drug when they don’t have a prescription or don’t take the drug as prescribed (like doubling their dose or taking extra when they have an exam).

Stimulants: Enhancing Focus or Creating Dependence?

The occasional use of a study drug, like once or twice before midterms, can be a regular practice for some college students. Those with heavy course loads or challenging classes, like pre-med or pre-law students, may feel particularly overwhelmed getting through school on their own strength. They can become reliant, and then addicted, to illicit or prescription stimulants like meth and Adderall. 

Some students may turn to caffeine, which is cheaper and more accessible than stimulants. They may take caffeine pills or regularly consume energy drinks. These pills and drinks can have 150-300 milligrams of caffeine each. The recommended daily limit is 400 milligrams, though one person might be more sensitive to caffeine than another. Drinking 3+ energy drinks a day, or having 3+ caffeine pills, puts a student at 450-900mg of caffeine. These high levels of caffeine can lead to heart issues5 and, rarely, death.

Cocaine: The Party Drug of Choice

Media still depicts cocaine as a “luxury” drug used by professionals and rich partygoers. College students’ attitude towards cocaine has become more positive6, leading to more experimentations and mimicking cocaine’s use as portrayed in media. 

Cocaine is a stimulant, causing a sense of euphoria and the ability to ‘let loose,’ which students might find appealing at a party—especially when it’s seen as the cool thing to do. But this can lead to addiction and health consequences, along with poor academic performance.

Ecstasy: The Allure of Raves and Euphoria

Ecstasy is a stimulant that can have psychedelic effects, which is why some college students use it at raves and parties for a more ‘trippy’ experience. Ecstasy often goes by the name Molly. It causes a strong feeling of euphoria and inhibition, but taking too much, too often can lead to addiction and other side effects. 

Ecstasy use correlates to dehydration and serotonin syndrome7, which happens when drugs or prescribed medications add too much additional serotonin. Young, thrill-seeking college students may be especially at-risk of taking too much ecstasy and becoming dangerously dehydrated, addicted, or sick from serotonin syndrome.

Vaping and Synthetic Drugs: Emerging Trends

Vaping Nicotine and Cannabis

College students and young adults in general vape more than older adults8. Vaping is generally seen as a safe alternative to cigarettes (it’s not). Nicotine vapes often come in appealing packaging and with tasty flavors, which a study found was one of the top reasons college students vape

Cannabis vapes often have flavoring too, and offer greater convenience compared to smoking a bong or blunt. Students may find this component especially beneficial, but it makes the likelihood of regular use and addiction, plus negative health effects, much higher.

Students can vape other drugs too, including synthetic drugs.

Synthetic Drugs

Synthetic drugs and designer drugs mimic ‘pure’ drugs with natural origins. For example, fentanyl is a synthetic opioid whose natural origin is the opium poppy plant. Synthetic marijuana, or synthetic cannabinoids, mimic the effects of the marijuana plant.

Some synthetic drugs come from clandestine labs and undergo zero quality control or testing. Manufacturers may market them as ‘supplements’ that are ‘not intended for human consumption.’ College students may purchase and take these drugs not knowing their addictive potential, or how they interact with other substances.

Factors Influencing Drug Use: Peer Pressure and Stress

A theme of stress and a desire to connect with others emerges throughout the college experience. Add in a greater tendency for experimentation and thrill-seeking, and you capture more of the landscape for college students and young adults.

Many students face extreme academic pressures and stress, which can lead to mental health conditions like depression and anxiety. Some students alleviate symptoms by chemically altering their state of mind. For example, a study on college students who vape8 reported a top reason was to “improve depression.”

Without effective on-campus support, students may turn to substances to manage stress. College campuses can help by improving access to their counseling services and educating students on the risks of substance use, and what to do if they need help. 

Consequences of Substance Use: Health Risks and Academic Impact

Substance use in college can lead to poor academic performance, below-average grades, lost scholarships, and expulsion. Many colleges have guidelines on substance use and documented consequences, especially as it relates to performance-boosting drugs.

Students also risk health consequences from substance use, including

  • Uncomfortable withdrawal symptoms
  • Higher risk of cancer from the carcinogens found in nicotine
  • Lung and cardiovascular diseases
  • Skin lesions
  • Dehydration
  • Weight loss
  • Addiction
  • Organ damage/failure

Treatment Options and Recovery Resources

Campus Resources

College students have a myriad of recovery resources available to fit their needs. For example, many college campuses offer free or discounted mental health care. Most campuses also have infirmaries that can assess a student’s physical health and recommend the next steps in their care. These clinics can also distribute medications and treat wounds.

Importantly, more colleges now have Naloxone kits available throughout campus. This means you have better access to the overdose-reversing medication Naloxone, which is easy to use and effective. If you notice signs of an overdose, including shallow breathing, blue lips, and unconsciousness, call 911 and administer Naloxone as soon as you can.

Off-Campus Treatment

College students can access off-campus recovery resources via public transit, their own car, carpooling, or by using virtual services. Off-campus treatment includes

  • Residential rehabs, where patients live at a treatment center for 28+ days and receive intensive treatment. Some centers, especially ones specifically for college-aged patients, allow time for schoolwork and attending classes online.
  • Outpatient care, including day treatment (most intensive), intensive outpatient, and general outpatient (least intensive). These structured programs offer robust care with the flexibility students often need to continue attending school.
  • Holistic and alternative treatments like acupuncture, ketamine therapy, yoga, and creative arts.
  • Therapy sessions as needed.
