Substance use in the workforce is the presence of alcohol and drug use disorders among people who hold jobs, and the population it describes is large. Combined 2008 to 2012 data from the National Survey on Drug Use and Health show that 9.5 percent of adults aged 18 to 64 employed full time met criteria for a past-year substance use disorder, 8.7 percent used alcohol heavily in the past month, and 8.6 percent used an illicit drug in the past month, per the SAMHSA report Substance Use and Substance Use Disorder by Industry.
The employment consequence is measurable in days. Parsley, Ian C. and colleagues' 2022 study "Association Between Workplace Absenteeism and Alcohol Use Disorder From the National Survey on Drug Use and Health, 2015-2019," published in JAMA Network Open, analyzed 110,701 full-time employed adults and found that severe alcohol use disorder is associated with about 32 missed workdays per year, against 13.0 days for workers with no alcohol use disorder.
Prevalence, absence, industry concentration, and job protection are four separate questions with four separate answers.
How Many Full-Time Workers Have a Substance Use Disorder?
Full-time workers report substance use disorder at 9.5 percent across all industries, meaning roughly 1 in 10 people working 35 or more hours per week met the diagnostic threshold in a given year. That figure comes from SAMHSA's Center for Behavioral Health Statistics and Quality, whose industry report on substance use and substance use disorder pooled five years of National Survey on Drug Use and Health interviews with adults aged 18 to 64 employed full time.
Two clarifications keep the 9.5 percent figure honest. The measure counts dependence on or abuse of alcohol or illicit drugs under DSM-IV criteria, which is narrower than the current DSM-5 substance use disorder construct. The survey also draws its denominator from people who were working, so it describes employed adults specifically rather than the general population. The pooled 2008 to 2012 window is also the most recent period for which SAMHSA has published substance use disorder rates by industry, because later National Survey on Drug Use and Health cycles report national totals without this industry breakdown. What has not changed is the arithmetic that follows from a workforce prevalence near 10 percent, which is that absence becomes an employer-scale number.
How Many Workdays Does Alcohol Use Disorder Cost Each Year?
Alcohol use disorder costs an escalating number of workdays as severity rises, from 17.7 days per year at mild severity to 32.3 days at severe, against 13.0 days for workers with no alcohol use disorder. Parsley and colleagues calculated those annualized figures from monthly self-reported absences among 110,701 full-time employed adults in the 2015 to 2019 National Survey on Drug Use and Health.
The severity gradient is the study's central finding, and the table below reproduces it with the published confidence intervals so the size of each step is visible.
| Alcohol use disorder severity | Missed workdays per year (95% CI) | Missed workdays per month (95% CI) |
| No alcohol use disorder | 13.0 (12.7-13.2) | 1.08 (1.06-1.10) |
| Mild | 17.7 (16.4-19.1) | 1.48 (1.36-1.60) |
| Moderate | 23.6 (21.5-25.7) | 1.97 (1.79-2.15) |
| Severe | 32.3 (27.5-37.0) | 2.69 (2.28-3.09) |
Aggregated across the workforce, the study attributes approximately 232 million absences per year to alcohol use disorder, split as 133.3 million from mild cases, 53.3 million from moderate, and 46.6 million from severe. Relative to workers without alcohol use disorder, severe alcohol use disorder raised the adjusted odds of substantial absenteeism, defined as 3 or more days missed per month, by a factor of 1.71 (95% CI, 1.41-2.07) for illness or injury and 2.81 (95% CI, 2.36-3.36) for skipping work. The National Safety Council reports the same pattern across all substances rather than alcohol alone: workers with a substance use disorder miss 24.6 days per year, against 15 days for the typical worker. Where those days concentrate is an industry question.
Which Industries Report the Highest Substance Use Rates?
Substance use rates vary roughly threefold across industries, with accommodations and food services highest at 16.9 percent past-year substance use disorder and educational services lowest at 5.5 percent. SAMHSA's industry analysis of combined 2008 to 2012 survey data classified full-time workers aged 18 to 64 into 19 industry groupings using the Census Bureau's North American Industry Classification System.
Three measures split differently across industries, so the table below reports each one with its highest and lowest industry rather than collapsing them into a single ranking.
| Measure | All full-time workers | Highest industry | Lowest industry |
| Past-year substance use disorder | 9.5% | Accommodations and food services, 16.9% | Educational services, 5.5% |
| Past-month heavy alcohol use | 8.7% | Mining, 17.5%; construction, 16.5% | Health care and social assistance, 4.4% |
| Past-month illicit drug use | 8.6% | Accommodations and food services, 19.1% | Public administration, 4.3% |
SAMHSA tested each gap against the age and gender composition of the industry, and the results diverge. Construction's heavy drinking rate held up after that adjustment, which points to something specific about the industry. Mining's did not, and neither did the accommodations and food services disorder rate, which means the demographic makeup of those workforces accounts for the difference. Composition and occupation are therefore two distinct explanations, and both operate.
Why Does Occupation Change Substance Use Risk?
Occupation changes risk through 4 documented pathways: workforce age and gender composition, workplace access to the substance, schedule and shift structure, and the drinking norms of the work culture. SAMHSA's adjustment analysis isolates the first pathway directly, and the industries that stayed elevated after adjustment implicate the other three.
Age composition does the heaviest statistical work. Adults aged 18 to 25 report higher substance use rates than older adults, and men report higher rates than women, so youth-dominated and male-dominated industries carry higher raw rates before anything about the job is considered. NIDA's research-based prevention guide, Preventing Drug Use among Children and Adolescents, adds a developmental mechanism that reaches into working life: entering the workforce is itself a life transition, and transitions are the periods when risk for alcohol and other drug problems rises. The same guide finds that new roles operate as protection once they become more important to a person than substance use. That double edge is the reason a job is worth protecting during treatment, and federal regulation defines exactly how far that protection extends.
What Job Protections Apply to Someone Entering Treatment?
Federal law protects the treatment, not the use: under 29 CFR 825.119 substance abuse may be a serious health condition eligible for Family and Medical Leave Act leave when it meets the serious-health-condition conditions at 29 CFR 825.113 through 825.115, and only when the leave is taken for treatment by a health care provider, because absence because of the employee's use of the substance does not qualify. Leave for treatment also requires a health care provider's referral where the provider is not the one delivering the care.
The entitlement itself, set out at 29 CFR 825.100, is up to 12 workweeks of job-protected unpaid leave in any 12 months, and the regulation permits leave to be taken intermittently rather than in one continuous block in certain cases.
The same regulation sets a limit that people entering treatment need stated plainly. Taking FMLA leave for treatment does not prevent an employer from acting on an established substance abuse policy that has been applied non-discriminatorily and communicated to all employees, and an employee subject to that policy is terminable under it whether or not FMLA leave is in progress. The employer is barred from acting against the employee for having exercised the right to take the leave. The regulation extends the same coverage and the same protection to an employee taking leave to care for a covered family member in treatment. New Jersey adds a state layer through Temporary Disability Insurance, and the practical mechanics of assembling medical certifications, short-term disability paperwork, and return-to-work documentation are set out in the guide to FMLA and short-term disability for addiction treatment. Paperwork is one half of keeping a job through treatment. Scheduling is the other.
How Does a Person Get Treatment Without Losing Their Job?
A person keeps working through treatment by entering an outpatient level of care, which delivers clinical hours around a work schedule instead of requiring residence in a facility. Outpatient and intensive outpatient programming is the level of care that makes employment and treatment simultaneous, and it is the level most working adults enter.
Valley Spring Recovery Center runs its outpatient levels of care at 830 Broadway in Norwood, New Jersey, with case management that handles employer documentation, union coordination, and court and Intoxicated Driver Resource Center requirements alongside clinical care. The center's Working Professionals Rehab in New Jersey track exists for the specific problem this page describes, which is a person holding a job they cannot afford to lose while a substance use disorder progresses. Admissions staff at (855) 924-5320 complete a free, confidential pre-assessment at any hour. The related question of how recovery and employment coexist after treatment starts is covered in the guide to addiction recovery without quitting your job. Attendance data answers whether that coexistence holds.
What Happens to Attendance After Someone Enters Recovery?
Attendance improves past baseline: workers in recovery from a substance use disorder miss 10.9 days per year, fewer than the 15 days missed by the typical worker and well under the 24.6 days missed by workers with an untreated disorder. The National Safety Council published those three figures together as the basis of its employer substance use cost calculator.
The ordering of those numbers is the finding that matters to an employer weighing whether to support treatment, and it depends on how the National Safety Council defines the recovery group: people who report having received substance use treatment in the past and who have had no substance use disorder in the last 12 months. Measured that way the recovery figure is not merely better than the disorder figure, it is better than the workforce average, which the Council measures as absence for illness, injury or reasons other than vacation and holidays. Recovery in this sense is a maintained state rather than a completed event, and the practices that maintain it are documented in the overview of recovery from addiction. A person reading these numbers about their own attendance record, or a manager reading them about a team member, has the same next step available: a confidential assessment that establishes whether a diagnosis is present and which level of care fits the work schedule, before absence becomes a disciplinary matter rather than a clinical one. The parent library of drug addiction statistics sets these workforce figures against national prevalence and overdose data.
What Are the Most Common Questions About Substance Use in the Workforce?
The 6 questions below cover prevalence, absenteeism, job protection, and disclosure facts people search most about substance use at work.
What Percentage of People With Addiction Are Employed?
SAMHSA found that 9.5 percent of adults aged 18 to 64 working full time met past-year substance use disorder criteria in its 2008 to 2012 industry analysis. Substance use disorder is common inside the employed population, not confined outside it.
How Many Workdays Do Workers With Alcohol Use Disorder Miss?
Severe alcohol use disorder is associated with about 32 missed workdays per year, moderate with 23.6, and mild with 17.7, against 13.0 for workers without the disorder, per Parsley and colleagues' 2022 JAMA Network Open analysis.
Does FMLA Cover Rehab?
Yes, for treatment. Under 29 CFR 825.119 substance abuse may be a serious health condition when it meets the conditions at 825.113 through 825.115 and leave is taken for treatment by a health care provider. Absence because of use is not covered.
Can an Employer Fire Someone for Entering Treatment?
An employer cannot act against an employee for exercising the right to take FMLA leave. An employer with an established, communicated, non-discriminatorily applied substance abuse policy retains the ability to terminate under that policy, per 29 CFR 825.119.
Which Industry Has the Highest Rate of Substance Use Disorder?
Accommodations and food services, at 16.9 percent past-year substance use disorder among full-time workers, per SAMHSA's industry report. That gap narrowed after adjusting for the industry's age and gender composition.
Do Workers in Recovery Miss More Work?
No. Workers in recovery, treated in the past with no substance use disorder in the last 12 months, miss 10.9 days per year, fewer than the 15 days missed by the typical worker, per the National Safety Council.
