Drug & Alcohol Policy (Singapore)

A Drug & Alcohol Policy in Singapore documents the organisation's approach and the obligations placed on those it covers.

The Workplace Safety and Health Act 2006 (Cap. 354A, WSHA), administered by the Ministry of Manpower (MOM), imposes a general duty on employers under Section 12 to take reasonably practicable measures to confirm the safety and health of employees at the workplace. An employee who is impaired by drugs or alcohol poses a foreseeable risk to their own safety and the safety of co-workers, visitors, and members of the public. The Workplace Safety and Health (General Provisions) Regulations require employers in prescribed workplaces to implement safety management systems that address foreseeable risks — including impairment from substance use.

The Employment Act 1968 (Cap. 91) provides the statutory framework for the employment relationship, including the employer's right to take disciplinary action for misconduct. Section 14 of the Employment Act permits an employer to dismiss an employee without notice for misconduct — and reporting to work under the influence of drugs or alcohol constitutes misconduct justifying summary dismissal, provided the employer conducts a proper inquiry. The Employment Act also requires employers to maintain written terms and conditions of employment (Key Employment Terms, or KETs) and to communicate workplace rules clearly to employees.

Singapore's zero-tolerance approach to drugs is reflected in the mandatory death penalty for trafficking in specified quantities of controlled substances (Section 33 of the MDA, read with the Second Schedule), mandatory minimum sentences for repeat drug offenders, and compulsory urine and hair testing powers granted to CNB officers under Section 31 of the MDA. The CNB conducts random drug testing at entertainment venues, workplaces, and during traffic stops, and employers who become aware that an employee has consumed a controlled substance are expected to cooperate with CNB investigations.

For alcohol, Singapore regulates public consumption through the Liquor Control (Supply and Consumption) Act 2015 (No. 5 of 2015), which restricts the hours and locations of alcohol consumption in public places. While there is no general statutory prohibition on alcohol consumption by adults in private settings, the Road Traffic Act (Cap. 276) criminalises drink-driving with a blood alcohol concentration exceeding 80 milligrams per 100 millilitres of blood, and the WSHA obliges employers to prevent alcohol-impaired employees from operating machinery or performing safety-critical tasks.

Section 31 of the MDA grants CNB officers the power to require any person to provide a urine specimen for drug testing, and Section 31(4) creates a rebuttable presumption that the person consumed the detected substance. Section 12 of the WSHA imposes a general duty on employers to take reasonably practicable measures addressing foreseeable workplace hazards including substance impairment. The National Council Against Drug Abuse (NCADA), established under the Ministry of Home Affairs, coordinates anti-drug education campaigns that employers may reference in their workplace policies.

A Drug and Alcohol Policy is needed whenever an employer operating in Singapore seeks to establish clear rules governing substance use and impairment in the workplace, meet statutory safety obligations, and protect the organisation from liability.

Every employer with employees performing safety-sensitive work — including construction (regulated by the Building Control Act, Cap. 29, and the WSHA Construction Regulations), manufacturing, transport and logistics, marine and offshore, and healthcare — should implement a written drug and alcohol policy. MOM's Workplace Safety and Health Council (WSHC) guidelines identify impairment as a workplace hazard that must be addressed through a safety management system under the WSHA. Employers in these sectors face enhanced regulatory scrutiny and should document their substance use policies as part of their safety management documentation.

Employers in the financial services sector regulated by the Monetary Authority of Singapore (MAS) — including banks, insurance companies, and capital markets intermediaries — should implement drug and alcohol policies as part of their broader conduct and compliance frameworks. MAS Guidelines on Individual Accountability and Conduct require senior managers to maintain standards of conduct, and substance impairment affecting an employee's judgment or performance may constitute a breach of these standards.

Employers of foreign workers on Work Permits, S Passes, and Employment Passes should include drug and alcohol policy acknowledgments in their onboarding documentation. MOM's work pass conditions require employers to take responsibility for the conduct of foreign employees, and a foreign employee convicted of a drug offence faces mandatory cancellation of their work pass and deportation. The Immigration Act (Cap. 133) bars persons convicted of drug offences from re-entering Singapore.

Employers responding to a workplace incident involving substance impairment — such as an accident, injury, or near-miss — should implement or update their policy immediately. Under Section 11 of the WSHA, every workplace incident resulting in death, major injury, or dangerous occurrence must be reported to MOM. An inadequate or non-existent drug and alcohol policy may be cited as evidence of the employer's failure to take reasonably practicable measures to address a foreseeable risk.

Employers with Employee Assistance Programmes (EAPs) or those affiliated with the National Council Against Drug Abuse (NCADA) campaigns should reference these support resources in their policy, demonstrating a balanced approach that combines enforcement with rehabilitation support.

A Drug and Alcohol Policy for a Singapore workplace must contain the following elements to comply with the Misuse of Drugs Act 1973 (Cap. 185), the Workplace Safety and Health Act 2006 (Cap. 354A), and the Employment Act 1968 (Cap. 91), and to withstand challenge in the Employment Claims Tribunals (ECT) or the Singapore courts.

Policy statement and purpose must declare the employer's position on drug and alcohol use in the workplace, reference the applicable legislation (MDA, WSHA, Employment Act), and state the policy objectives — protecting employee safety, maintaining workplace productivity, and complying with Singapore law. The statement should confirm that the policy applies to all employees regardless of position, seniority, or employment type (permanent, fixed-term, part-time, contract, and foreign workers on work passes).

Scope and definitions must define the prohibited substances — including all controlled substances listed in the First Schedule to the MDA (such as cannabis, methamphetamine, heroin, cocaine, and ketamine), prescription drugs that impair workplace performance when not used as prescribed, and alcohol above specified limits during working hours or on company premises. The definition section should clarify terms such as "workplace" (including remote work locations, client premises, company vehicles, and business travel), "working hours" (including overtime and on-call periods), and "impairment" (observable symptoms or test results exceeding specified thresholds).

Prohibited conduct must enumerate the specific behaviours that violate the policy: consuming, possessing, distributing, or trafficking controlled substances on company premises or during working hours; reporting to work under the influence of drugs or alcohol; consuming alcohol during working hours except at authorised company events; operating machinery, driving company vehicles, or performing safety-critical tasks while impaired; and refusing to submit to testing when required by the policy.

Testing and enforcement procedures must specify the circumstances under which testing may be conducted — pre-employment screening, post-incident testing, random testing, and for-cause testing based on reasonable suspicion of impairment. The policy should describe the testing methods (urine testing consistent with CNB procedures, breathalyser testing for alcohol, or hair follicle testing), the chain of custody requirements, and the employee's right to request a confirmatory test. All testing must comply with the Personal Data Protection Act 2012 (PDPA) — drug test results constitute sensitive personal data, and the organisation's Data Protection Officer must confirm that collection, use, and disclosure of test results comply with the PDPA's consent and purpose limitation obligations.

Consequences of violation must state the disciplinary actions for each category of breach — ranging from a formal written warning for a first alcohol-related offence to summary dismissal for any drug-related offence or repeated alcohol violations. The policy must confirm that summary dismissal for misconduct will follow the inquiry procedure required by Section 14 of the Employment Act. Employees dismissed for drug-related offences should be informed that the employer may be required to report the offence to the CNB under the MDA.

Support and rehabilitation section should describe the employer's Employee Assistance Programme (EAP), if available, referral pathways to the National Addictions Management Service (NAMS) operated by the Institute of Mental Health (IMH), and voluntary self-disclosure provisions allowing employees to seek help without automatic disciplinary action (subject to limitations where safety-critical roles are involved). The forms-legal.com template includes EAP referral language and NAMS contact details specific to Singapore.

Review and communication provisions must state how the policy will be communicated to employees (written distribution, induction briefings, annual refresher training), how employees acknowledge receipt and understanding (signed acknowledgment forms), and the schedule for policy review and update (at least annually or upon changes to applicable legislation).
