The impaired student: Substance abuse in medical students

Substance use disorder has been a significant issue within the medical profession throughout history. It is recognised as an important issue of concern, particularly due to its associated mortality, morbidity and social consequences. Although a substantial body of literature addresses this issue amongst doctors, there is little discussion focusing on medical students. This review summarises the existing literature available on the epidemiology, common  presenting  features,  management,  legal  implications and mandatory notification requirements of substance abuse in the medical student. Limited evidence suggests concerning levels of hazardous alcohol use exists in medical students, however alcohol and drug use is not comparatively higher than the general student population. While early detection is optimal for harm prevention, signs and symptoms of substance abuse are subtle and easily missed. Prevention and early intervention is critical, and it is important for students to recognise possible signs of substance abuse  in  their  colleagues,  as  the  biggest  barrier  to  treatment is   denial.   Once   detected,   current   evidence   from   Physician Health Programs suggests a service to manage the student’s multidisciplinary  care,  follow  up  and  return  to  study  obtains the best outcome. As a chronic medical condition that carries significant risk of harm to the impaired student – and potentially to patients – all health professionals should be aware of this issue and their mandatory reporting obligations.


Substance use disorder (SUD) amongst doctors is an issue of significant concern. It is estimated the lifetime prevalence of substance abuse in Australian doctors is approximately 8%. [1] There is limited literature or discussion, however, addressing this issue in the context of the most junior members of the profession, medical students. The university experience is often coupled with alcohol use and occasionally with casual illicit drug use, but this is, to some extent, accepted, perhaps as part of youthful exuberance, experimentation or a rite of passage. [2] For some, however, this substance use may manifest as, or progress to, substance abuse: a pattern of drug or alcohol use that is detrimental both to the individual and to society. [3] For the substance-abusing medical student, there is a wide scope for serious implications personally, professionally and with the public.

This article aims to highlight the importance of this topic and provide information  on  the  concept  of  substance  use  disorder,  common signs  of  substance  abuse,  management,  reporting  requirements and legal implications. It also addresses why it is imperative there is awareness for this issue in medical students to prevent serious health consequences and risk to the public.

Terms within this article

Substance use disorder or substance abuse: A chronic condition characterised by a pathological pattern of behaviours related to substance use, manifesting as two or more symptoms of: impaired control of drug use; social impairment at work, school or home; risky use; tolerance or withdrawal. [4]

Substance   dependence:   An   inability   to   control   substance   use, despite problems caused by use. [5] This may manifest physically or psychologically with tolerance or withdrawal. Dependence and drug abuse are not separate entities within the Diagnostic and Statistical Manual 5 (DSM-5), however these terms are prevalent in the cited literature.

Impairment: A physical or mental impairment, disability, condition or disorder (including substance abuse or dependence) that detrimentally affects, or is likely to detrimentally affect, a practitioner’s capacity to practise the profession. [6]

How common is student substance abuse?

There  is  little  recent,  comprehensive  data  on  student  substance abuse, with most studies occurring in the 1980s-1990s and concerning rates of use rather than abuse. [5] Furthermore, prevalence studies are hindered by surveys requiring self-reporting of abuse and varied case definitions. With these limitations, the available data on student substance use is summarised below.

Alcohol use and abuse

Use of alcohol in the general student population is common, with consumption occurring in approximately 96% of Australians aged 18-21 years. For medical students in particular, international studies have indicated that rates of lifetime alcohol usage range between 62.3% and 98.1%. [2,5,7-11] Male medical students have higher levels of intake compared to females and hazardous alcohol use is significantly higher in those with high levels of psychological distress. [12] The BeyondBlue study of medical students and doctors found concerning rates of moderate-risk (21%) and high-risk (4%) drinking amongst medical students in Australia. [12] Moderate risk is classed as a hazardous intake level and high risk is associated with harmful drinking patterns, as assessed by the World Health Organisation Alcohol Use Disorders Identification Test (AUDIT). [12] This level of drinking, however, appears low in comparison to the general university population, which has an approximately 8.1% rate of harmful drinking. [12,13]

Internationally, 50% of medical students in the UK consumed above the recommended amount. [8] Using the CAGE questionnaire (Table 1),  22.4%  of  junior  Turkish  medical  students  and  52.5%  of  Irish medical students were found to be CAGE positive. [10,11] Of medical students who drink, 60.5% of men and 72.2% of women engaged in binge drinking, with 36.8% of men and 58.2% of women suggesting that their performance had been affected at least one day in the past month by alcohol consumption. [8] While the BeyondBlue study noted that drinking levels decreased with age, other data suggests that as students progress through their clinical years and beyond, a greater number of students drink, and drink more heavily. [10,14]


Drug use

Rates of illicit substance abuse in medical students appear comparable to, or less than that of, the general population, with data falling between 3-10%. [17] BeyondBlue reports show low rates, with 10.2% of students engaged in illicit drug use 2-3 times a month, and 0.5% 1-6 times a week. [12]

Drugs of abuse may be recreational, for example cannabis or stimulants, or prescription, such as benzodiazepines, opiates or propofol. Amongst junior students, the most common drug of abuse is cannabis and is often likely to be the first used before medical school. [2,8,14] Other illicit or prescription drugs are less common, however alcohol and cannabis might be considered gateway drugs to these. In one study, those who used cannabis were more likely to be drinking heavily than non-users and those who used illicit drugs had also used cannabis. [14] It is reported that medical students are increasingly being offered illicit drugs, and more are accepting them. [11] Abuse of illicit drugs, such as cocaine, or prescription drugs, such as benzodiazepines, was more likely to occur once at university. [2]

Notably, as students progress to become doctors, patterns of drug abuse change with increasing rates of prescription drug abuse. [5,10] Drugs of choice vary by medical specialty as to what is easiest to obtain; for example, anaesthetists have high rates of propofol and opiate abuse, whereas other specialties such as psychiatrists are more likely to abuse benzodiazepines. [1,18,19].

Recognition of substance abuse

Signs  of  substance  abuse  are  both  subtle  and  varied,  and  can  be easily missed. They are often disguised by the affected practitioner. Denial is common, and often it is the person with the disorder that is last to acknowledge a problem. [20] Early detection can prevent the development of significant harm. Table 2 lists possible emotional, social and physical signs of alcohol or drug abuse.


Reporting requirements

The impaired physician is a concept defined under national law as a physical or mental impairment, disability, condition or disorder (including substance abuse or dependence) that detrimentally affects, or is likely to detrimentally affect, a practitioner’s capacity to practise the profession. [6] For a student, the impairment must detrimentally affect, or be likely to detrimentally affect, the student’s capacity to undertake clinical training. This means impairment is defined by a student’s reduced capacity to learn, a quite broad definition. For a notification to the Australian Health Practitioner Regulation Agency (AHPRA) to be made, however, there must be a belief that their impairment could cause public harm, for instance intoxication at work. [6,23]

Two forms of notification can be made to AHPRA. [6] Mandatory notifications compel  practitioners  or  education  providers  to  make a notification if they form a reasonable belief that a student has an impairment that may place the public at substantial risk of harm in the course of their clinical training, or are practising whilst intoxicated with alcohol or drugs. Voluntary notifications about a student can be made by anyone if they form a reasonable belief that a student has an impairment that may cause public harm.

Consequences  of  notification  may  include  the  suspension  of  a student’s registration, the imposition of conditions of practice, further health assessment, and possible long-term impacts on their ability to continue their studies and future registration (depending on expert advice in each case). [6,23] For students, it is important to recognise the possible future career consequences of alcohol or drug abuse.

Management of the impaired student

Treatment  of  impairment  is  both  complex  and  individualised  and there is no standard protocol for treating impaired medical students. Treatment may be managed by the student and their treating team, or may be arranged by AHPRA or the medical board as a result of a notification.  Individual  medical  school  impairment  policies  likely vary and are not reviewed here. A majority of reviewed American school policies require direct referrals for management of suspected substance abuse cases, and one third forego disciplinary treatment for those impaired students who self-refer to promote seeking early intervention. [5] Depending on the substance(s) involved, treatment may include features such as inpatient treatment and detoxification, 12 step programs or use of therapeutic agents (e.g. naltrexone). [3]

Referral to a long-term support program with a specific focus on doctors’ health is optimal. Within Australia, available services and models of support vary from state to state. Most states offer a Doctor’s Health Advisory Service telephone counselling service, with support offered by experienced practitioners. [24] The Victorian Doctors’ Health Program (VDHP) offers the only full-time physician health program (PHP) of its kind in Australia. It is confidential, independent of AHPRA and open to both doctors and medical students. [25] PHPs were pioneered in the United States to assist in the rehabilitation of impaired physicians. They do not directly provide treatment but provide evaluation and diagnosis, facilitation of formal addiction treatment, on-going confidential support, case management, biochemical and workplace monitoring,  and  return-to-work support  as  required  on a case-by-case basis. [25,26] A core component is an individualised care contract lasting up to five years to ensure compliance with the appropriate treatment plan devised. This may include a case manager, psychiatrist, addiction specialist, psychologist, general practitioner or social worker. Ongoing peer support is also recommended through a facilitated Caduceus collegial support group open to medical practitioners and students with substance abuse issues, and has been shown to play an important role in recovery. [1] The VDHP offers three types of programs of different levels of support, ranging from intensive case management to wellbeing and support programs and long term follow up, depending on what is required in each case and the phase of recovery. These programs are successful, with studies consistently demonstrating success rates of 75-90% after five years for American physicians treated through PHPs. [27,28] Preliminary data from the VDHP program indicates similar Australian five-year success rates. [25]

The evidence-based success of these programs suggests that similar services should be available for all doctors. However, cost is a significant issue. The average American state PHP costs USD$521,000 annually to manage between 65 to 75 physicians per year, primarily paid for by an additional $23 charge to licensing fees, whilst formal treatment costs are covered by health insurance and personal physician contributions. [27] It is important to note that some PHPs produce better outcomes than others and that implementation should replicate published successful models and be followed with outcome evaluations. [29,30]

Further to specific services available to doctors, there is a wealth of support available through the pastoral support and wellbeing services of universities that can be accessed in a student capacity. One proactive university  even developed and successfully implemented an Aid for the Impaired Medical Student program to oversee medical student recovery management, although little has been published on this recently. [31]

Fighting the “conspiracy of silence”

Boisaubin and Levine discuss the concept of a “conspiracy of silence” where the impaired physician, his/her colleagues, friends and family have a tendency to dismiss their suspicions and suppress their concerns, with a belief that the physician is fine, or capable of solving his/her issues. [32] They state “denial is the most consistent hallmark of this disease process, for both colleagues and the susceptible physician.” This is a key barrier to treatment, and only increases with professional advancement in a medical culture of not admitting weakness, let alone acknowledging the presence of a medical condition laden with stigma. Participants in the VDHP substance use programs were most likely to have been referred by colleagues, employers or treating doctors, compared to self-referral or referral from regulatory bodies. [1] This demonstrates the importance of students and educators being aware of the signs of substance abuse in others, and knowing the options available to assist.

Future implications

There is little data about the risks of student substance abuse, but death or near fatal overdose is the presenting symptom in 7-18% of doctors. [33] Alarmingly, recent data demonstrates anaesthetists abusing propofol have a 45% mortality rate. [19] Substance abuse is also often coupled with psychiatric morbidity and stress-related disorders. Harm to patients is a real risk, either indirectly through impairment of capacity and decision making, or directly, such as in the well-publicised case of the fentanyl-abusing doctor spreading Hepatitis C to women undergoing pregnancy terminations. [34]

There is no clear longitudinal data to demonstrate whether substance abuse as a student is associated with substance abuse as a doctor. This article does not enter the debate as to whether impairment due to substance abuse as a student should preclude a student pursuing a career intimately associated with a range of drugs of abuse, such as opiates. Without prescribing rights, students are more limited in their access to the wide range of substances, compared with their qualified colleagues. It was noted that, of those surveyed in an evaluation of the VDHP Caduceus program, substance abuse issues began in medical school for 16% of the respondents. [1] Furthermore, the diagnosis of alcohol abuse is commonly delayed, often for years, and can start with patterns of high risk drinking.


In conclusion, substance use disorder has enormous impacts, including health  issues,  patient  risk,  mandatory  notification  requirements, future career implications and ultimately escalation to more dangerous substances. It is a chronic medical condition and management requires a multidisciplinary team, long-term support, sensitivity and experience. It is important to recognise that, while medical students are often high functioning and high achieving and generally appear to have similar rates of substance use to the general university population, they are not immune to substance abuse issues. In a profession with high levels of psychological distress, burnout and minor psychiatric morbidity, it is necessary to have a higher index of suspicion. [12] The biggest barrier to treatment is denial, not only by the impaired student, but also by friends, family and colleagues. It would therefore seem imperative that student substance abuse is detected early and treatment provided immediately to prevent the serious consequences of ignoring the situation.
