Over 50s: Drug Advice
Drugs and drug use over 50: what’s worth knowing
Drug use among people over 50 is more common than many people realise, and it covers a wide range of substances, from cannabis and cocaine to prescription painkillers and sleep aids. This page looks at why drug use matters more after 50, what the specific risks are, and how to get support if you need it.
Your body handles drugs differently as you get older
Many people who use drugs in later life have been doing so for years. Others start or increase use in response to life changes. Either way, the body’s ability to process substances changes significantly after 50, meaning the same drug or dose can have a greater and more unpredictable effect.
Slower metabolism
Your body takes longer to break down and clear substances. Drugs stay in your system for longer, increasing the risk of overdose or unexpected side effects even at doses that once felt manageable.
Increased sensitivity
The brain and nervous system become more sensitive to drugs with age. Psychoactive substances including cannabis, opioids, and benzodiazepines can have stronger sedative or disorienting effects.
Medication interactions
People over 50 are more likely to be taking prescribed medications. Many drugs, including recreational ones, interact dangerously with common medicines for blood pressure, diabetes, heart conditions, or mental health.
Reduced physical resilience
Falls, accidents, and injuries linked to drug use are more serious after 50. Bones are less dense, recovery takes longer, and the cardiovascular system is under greater strain.
Drug use in later life takes many forms
It is worth being clear about what counts as drug use in this context. This page covers three overlapping areas.
Recreational and illicit drug use
Cannabis is the most commonly used illicit drug among over 50s and its use has increased significantly in this age group over the past decade. Cocaine, MDMA, ketamine, and amphetamines are also used, sometimes by people who have been using them since younger adulthood and have continued into later life. The risks associated with these substances increase with age, particularly around the heart, mental health, and cognition.
Prescription drug misuse
Prescription medications are more widely used after 50, and misuse is more common than is often acknowledged. This includes taking higher doses than prescribed, using medication more frequently than intended, using someone else’s prescription, or using medication to manage emotions rather than the condition it was prescribed for. Opioid painkillers, benzodiazepines (used for anxiety or sleep), and sleeping tablets are the most commonly misused prescription drugs in this age group.
Over-the-counter and other substances
Some people develop dependence on substances that do not require a prescription, including codeine-based painkillers, antihistamines used for sleep, and some cough medicines. Because these are legally available and widely considered safe, dependence can develop without the person recognising it as a problem. The risks increase with age and are compounded by interactions with other medications.
Why drug use can increase after 50
Drug use in later life is often connected to life events and changes that are common after 50. Understanding these triggers can help people recognise patterns in their own behaviour.
- Chronic pain that is not adequately managed through prescribed medication
- Retirement and the loss of daily structure, purpose, or professional identity
- Bereavement, loneliness, or social isolation
- Anxiety, depression, or other mental health difficulties
- Difficulty sleeping, leading to increasing reliance on sedatives or cannabis
- Continuing a habit from younger adulthood that has quietly intensified
- Reconnecting with recreational drug use in later life, sometimes after a long break
What drug use can do to your health at this stage of life
The health risks associated with drug use are more significant after 50. Some are specific to particular substances, others are general effects that are made worse by the physical changes that come with age.
Heart and circulation
Stimulants such as cocaine, MDMA, and amphetamines put significant strain on the heart. After 50, the cardiovascular system is less resilient, making heart attack, stroke, and irregular heart rhythm more likely during or after use.
Falls and injuries
Drugs that affect coordination, balance, or alertness increase the risk of falls and accidents. After 50, falls are more likely to cause serious injury and recovery takes longer.
Mental health
Drug use can cause or worsen anxiety, depression, and paranoia. Cannabis in particular has been linked to increased rates of psychosis, especially with high-potency products. Mental health difficulties already become more common in later life, and drug use compounds this.
Dependence and withdrawal
Physical and psychological dependence can develop more quickly in later life. Withdrawal from some substances, including benzodiazepines and opioids, can be medically serious and should never be managed alone.
Memory and cognition
Regular use of cannabis, opioids, benzodiazepines, and other substances accelerates cognitive decline. This is a particular concern after 50, when cognitive health is already more vulnerable.
Overdose risk
Tolerance changes with age and with patterns of use. People returning to a substance after a break, or using a familiar dose with an older body, face a significantly increased risk of overdose.
What to know about specific substances
Different substances carry different risks. Here is a brief guide to some of the most commonly used in this age group.
Cannabis
Cannabis is now much stronger than it was several decades ago. High-potency products carry a greater risk of anxiety, paranoia, and psychosis, and the sedative effects are amplified with age. Regular cannabis use also affects sleep quality, memory, and motivation. If you have a heart condition, smoking cannabis in particular carries additional risk.
Cocaine and stimulants
Cocaine puts immediate strain on the heart and blood vessels. After 50, the risk of heart attack during or shortly after cocaine use is significantly higher than in younger adulthood. Amphetamines and MDMA carry similar cardiovascular risks, as well as a greater impact on sleep, mood, and mental health in the days following use.
Opioids (including prescription painkillers and heroin)
Opioids carry a high risk of dependence and a serious risk of overdose, particularly when tolerance has changed or when combined with alcohol, benzodiazepines, or other sedatives. Prescription opioids such as codeine, tramadol, and oxycodone are included here. If you are concerned that you are using more than prescribed, or that you are using them to cope rather than to manage pain, it is worth speaking to someone.
Benzodiazepines and sleeping tablets
Benzodiazepines (such as diazepam, lorazepam, and temazepam) and Z-drugs (such as zopiclone and zolpidem) are prescribed for anxiety and sleep. They are effective short-term but carry a significant risk of dependence with longer use. After 50, they also increase the risk of falls, confusion, and memory problems. If you have been using them for longer than a few weeks and feel unable to stop, support is available.
Mixing substances: combining any drug with alcohol, or using more than one drug at the same time, significantly increases the risk of serious harm. This applies to recreational drugs and to prescribed medications. If you are unsure whether your medications interact, speak to your GP or pharmacist.
