Festival season and drug use: what you need to know

Every summer, thousands of people across Ireland head to fields, parks, and arenas to take part in one of the country’s most beloved summer traditions: the music festival.

For many attendees, festivals are a positive, memorable experience. But alongside the music and the shared sense of occasion, festival season also brings a well-documented rise in recreational drug use.

Evidence consistently shows that festivals are high-risk settings for drug and alcohol-related harm. For some, this is a personal safety concern. For others, like parents of teenagers or young adults, it raises difficult questions about what signs to look for, and what options are available if concerns arise.

Here, we explore what you need to know about drug use at festivals including commonly misused substances, the dangers posed by contaminated drugs and so-called “legal highs”, and how at-home drug testing can provide clarity and peace of mind when it matters most.

The scale of the issue

Drug use in Ireland remains a persistent public health concern, and festival environments amplify the risks considerably.

A 2026 study published in the journal Addiction, using data from the nationally representative Growing Up in Ireland study, found that close to 1 in 4 young adults in Ireland (approximately 23% of 20-year-olds) engage in polysubstance use, consuming multiple psychoactive substances within a short timeframe.

The most common substances involved included alcohol, cannabis, cocaine, and ecstasy, with a further 7% classified as heavy polysubstance users, regularly combining ketamine and other drugs.

Critically, the same research found that having friends who used cannabis at age 17 was associated with a substantial increase in the odds of belonging to a polysubstance group by age 20, highlighting the significant role that peer influence plays in festival environments.

For parents, these figures underline why awareness matters. Many young people attending festivals will experiment with substances for the first time, often without access to accurate information about the risks involved.

Common drugs associated with festival season

While alcohol remains the most widely consumed substance at festivals, a range of illegal drugs are also used.

Understanding what these substances are and the risks they carry is an important first step. Whether you’re a young person making your own informed choices, or a parent trying to understand what your child might encounter.

The substances most associated with festival settings include:

MDMA (ecstasy)

One of the most prevalent festival drugs, MDMA produces feelings of euphoria, emotional closeness, and heightened sensory experience.

Typically taken as a pill or powder, risks include overheating, dehydration, and in serious cases, organ failure. The strength and content of pills vary enormously and cannot be determined by appearance alone.

Cocaine

A powerful stimulant associated with increased energy and confidence.

Cocaine is Ireland’s most treated drug problem, accounting for 40% of all drug treatment cases in Ireland in 2024 alone; the highest figure ever recorded, according to the Health Research Board.

Short-term risks of cocaine use include elevated heart rate, anxiety, and in rare cases, cardiac arrest.

Ketamine

A powerful anaesthetic used in both human and veterinary medicine, ketamine is increasingly used recreationally at festivals, particularly among younger attendees.

At high doses, it can cause disorientation, loss of consciousness, and serious bladder damage with prolonged use.

Cannabis

The most widely used illegal drug in Ireland, cannabis is commonly used at festivals. It’s most usually inhaled but can also be ingested in hash or resin form.

While often perceived as low-risk, it can trigger anxiety, paranoia, and in some individuals, acute psychotic episodes, particularly in high-potency forms.

Amphetamines (speed)

Amphetamines are stimulant drugs used to sustain energy and alertness over long periods. Sold illegally in powder and tablet form, they are often packaged in aluminium foil, plastic bags, or small balloons.

Risks of repeated use include elevated blood pressure, insomnia, and dependency.

New Psychoactive Substances (NPS) and so-called “legal highs”

Perhaps the most unpredictable category of all.

Despite the informal term, many of these substances are neither legal nor safe. Research confirms that use of NPS at festivals is most prevalent among younger festival goers, who may be drawn to them because they’re perceived as less risky than established illegal drugs. In fact, the opposite is often true.

The dangers of NPS and contaminated drugs

One of the most significant risks associated with drug use at festivals is not just what a substance does to the body, but what it contains.

The illicit drug market is entirely unregulated. There are no quality controls, and no guarantees that a substance sold as one thing contains what the buyer expects.

This means that many drugs purchased at or before attending a festival may be mis-sold or mixed with other substances without the user’s knowledge.

NPS, still sometimes referred to as “legal highs” – despite the majority now being controlled under Ireland’s Criminal Justice (Psychoactive Substances) Act 2010 – add another layer of unpredictability.

NPS are chemically engineered substances designed to mimic the effects of traditional controlled drugs such as opioids, stimulants, and cannabinoids, and pose significant health risks due to their unpredictable potency and toxicity.

A further, growing concern is the presence of synthetic opioids, particularly nitazenes, in the Irish and wider European drug supply.

The European Union Drugs Agency (EUDA) has flagged nitazenes as an emerging threat across EU member states, with these extraordinarily potent substances linked to a rise in drug-related deaths and increasingly found in street drugs without the user’s knowledge.

The consequences of taking an unknown or contaminated substance in a festival environment where medical help may not be immediately accessible, where dehydration and heat are additional factors, and where other substances may also have been consumed, can be severe, and in some cases fatal.

Why parents worry – and why that concern is valid

For many parents, the prospect of their children attending their first festival is a source of mixed emotions.

That concern is not unfounded. According to the Health Research Board, close to one in four young adults in Ireland engage in polysubstance use by the age of 20. Additionally, early alcohol use, peer influence, and parental substance misuse are all identified as risk factors for heavier drug involvement in later adolescence.

Festival environments present a particular challenge. Research indicates that the escapist atmosphere of festivals can lower inhibitions and promote riskier behaviours, while social norms endorsing excess and the ready availability of substances heighten the likelihood of drug use.

For a young person attending with friends – and without their parents – the social pressure to experiment can be significant.

Many young people who try drugs at festivals don’t consider themselves regular drug users. However, experimentation in a social setting, often with substances of unknown origin or strength, carries the same risks regardless of intent or frequency.

Open, honest conversation between parents and children remains one of the most effective tools available.

However, conversation alone is not always enough and for some parents, particularly those who notice changes in their child’s behaviour after a festival, there may be a need for clearer answers.

This is where at-home drug testing can be useful.

At-home drug testing: what it is and how it works
