# Substance abuse on site, alcohol, drugs and getting help
You're not the only one using booze, coke or painkillers to get through this job, but it is a safety issue, and there is help that won't automatically cost you your livelihood. The goal here isn't to preach; it's to be straight about risk, rights and ways out.
Quick rule of thumb: you don't have to go from "fine" to rehab overnight: the first step is usually smaller: admit to yourself it's more than just "a few beers" or "the odd line", talk to one person you trust, and ring a helpline that actually understands the job.
1. How common is it, really?
It's a lot more widespread than people admit.
- A Considerate Constructors Scheme survey found 59% of respondents were worried about the effects of drugs and alcohol in construction; 35% had seen colleagues under the influence at work, and about a quarter said drugs or alcohol had affected them at work through tiredness.
- A study of UK construction workers in treatment found over half reported alcohol use, with a high rate of co-existing mental health problems.
- Other research on construction workers shows significant use of tobacco, cannabis and alcohol, with high levels of dependence or misuse among those who do use.
On the ground that looks like: Friday lunchtime pints that creep into every day, weekend coke or weed that starts to spill into the week, and painkillers that were prescribed after an injury but never really stopped. This is normalised, but it's not harmless.
2. Why it's a safety problem, not just "your business"
Construction is full of safety-critical tasks, operating plant, driving, working at height, using power tools, dealing with electrics and hot works.
Drugs and alcohol:
- Slow reaction times and decision-making · bad news when you're on a saw, MEWP, crane or live services.
- Mess with balance and coordination · falls from height, slips, trips.
- Distort risk perception · more likely to cut corners or ignore procedures.
- Increase fatigue · especially alcohol and some drugs causing poor sleep, which then hits you on the next shift.
UK law is clear:
- Under the Health and Safety at Work Act, employers must protect workers' health and safety, and you must take reasonable care of yourself and others · that includes not being impaired by substances at work.
- If an employer knowingly lets someone work under the influence in a way that could cause harm, they can be in breach of their duty of care.
- The Road Traffic Act makes it a criminal offence to drive under the influence of drink or drugs · that applies just as much when you're driving between sites or in a work van.
So this isn't about anyone policing your private life. The red line is turning up or working impaired in a job where other people's lives depend on you.
3. Employer testing, discipline and dismissal, what they can and can't do
Testing
HSE-style guidance says employers should:
- Have a clear drug and alcohol policy, consulted with staff, that sets out when testing may happen (for example, pre-employment, random, "for cause" after incidents).
- Focus testing on safety-critical roles where impairment could have serious consequences (plant operators, drivers, people working at height, etc.).
- Get your consent for screening · in practice, most contracts and site rules make testing a condition of working there.
If you refuse a reasonable test under a clear policy, that can be treated as a disciplinary matter, sometimes like a positive test.
Dismissal
The Employment Rights Act allows dismissal for misconduct or capability, and drug/alcohol misuse can fall under either if it affects your work or breaches rules, but:
- Employers must follow a fair process · investigate, give you a chance to explain, follow their disciplinary procedure and consider options like support or redeployment, especially on a first issue.
- Dismissal is more likely to be seen as fair if you were working in a safety-critical role, broke a clear known policy (for example, zero tolerance), or repeatedly offended after being offered help.
Where someone asks for help before an incident, a lot of decent employers will try to treat it more like a health issue, offering support, temporary non-safety-critical duties, or time off for treatment, rather than jumping straight to the sack.
4. Painkillers, injuries and "legal" dependency
This one's common on site and rarely talked about:
- Construction is physical · backs, knees, shoulders, repetitive strain, injuries from accidents.
- People get prescribed opioid painkillers or strong meds short-term and then carry on using them just to get through the day.
- Long-term use can lead to tolerance, dependence and withdrawal, plus drowsiness and impaired judgement · all bad news when operating plant, at height or on tools.
If you're:
- Taking more than prescribed,
- Mixing painkillers with alcohol,
- Panicking when you run low,
it's worth seeing your GP and being honest. They'd rather help you taper safely or change treatment than see you wreck your health privately. NHS guidance and helplines can also signpost you to local substance misuse services.
5. Where to get confidential help (even if you're scared about work)
You've got more options than just HR. These don't ring your boss. You choose how much you say at work and when.
Helplines
- FRANK · 0300 123 6600 / talktofrank.com · free, confidential drug advice for anyone · can talk through what you're using, risks, and how to cut down or stop.
- Drinkline · 0300 123 1110 · free, confidential alcohol advice · from cutting down to more serious problems.
- Lighthouse Club · 0345 605 1956 · construction-specific helpline covering mental health, money and substance problems; can arrange further support and, in some cases, financial help if everything's tangled together.
NHS services
- Local NHS substance misuse services · NHS England signposts services for drugs and alcohol. You can self-refer in many areas · you don't always need to go through your GP.
If you do feel safe to tell your employer
- Ask about occupational health or any Employee Assistance Programme · many large contractors have confidential counselling or support lines built in.
- For safety-critical roles, they may need to move you temporarily off certain tasks while you get help · that's about keeping you and everyone else alive, not punishing you for being honest.
6. Straight talk
If you're using drink, coke, weed or painkillers to get through, you're not the only one, but sooner or later it will hit something you care about: your licence, your job, your health, or someone else's safety.
The first step is usually smaller than you think:
- Admit to yourself it's more than just "a few beers" or "the odd line".
- Talk to one person you trust.
- Ring a helpline that actually understands the job.
What to do next
- Today: if you know you're relying on something to cope, save one of the helpline numbers in your phone · FRANK (0300 123 6600), Drinkline (0300 123 1110), or Lighthouse Club (0345 605 1956).
- This week: if it's painkillers, book a GP appointment and be honest about how much you're taking and why · they won't judge you, and they can help you come off safely.
- If a mate is struggling: don't ignore it · a quiet "I've noticed you're hitting it hard, everything alright?" is enough to start. You're not there to fix them, just to crack the door open.
