Bromazolam is an illicit, unlicensed benzodiazepine—a psychoactive substance with no approved medical use in the UK. It’s often sold as diazepam in Wales, creating a significant substitution risk and unexpected potency for those who buy it.
Bromazolam was the most commonly identified illicit drug in Wales last year. In 2021, 61 drug misuse deaths in Wales involved benzodiazepines, up from 35 in 2020. The National Crime Agency is actively involved in tackling the issue of counterfeit benzodiazepines and synthetic opioids in Wales, reflecting the growing concern over illicit drug market regulation and enforcement.
Between 2023 and 2025 the rise of counterfeit “Valium” tablets, increasing benzodiazepine-related poisonings—benzodiazepines being a commonly identified chemical group in illicit drug samples—and mixing with synthetic opioids has made this a priority issue for health experts across Welsh communities.
What Is Bromazolam? (Definition and Pharmacology)
Bromazolam is a novel substances service concern—a designer benzodiazepine belonging to the triazolobenzodiazepine group, structurally related to alprazolam. It is a psychoactive drug with mind-altering effects. Bromazolam has no licensed medical use anywhere in the UK or EU. Like other benzodiazepines it acts on GABA-A receptors, causing sedation, muscle relaxation, reduced anxiety, impaired coordination and memory. Bromazolam is often sold under the guise of diazepam, which leads to a higher risk of harm due to its increased potency.
Evidence suggests bromazolam is more potent than diazepam on a milligram for milligram basis though exact equivalence is unknown. In Wales you may find:
Blue or white tablets pressed to look like 10mg diazepam\
Less commonly powders or liquids bought via social media, encrypted apps or so called online pharmacies
International forensic data from England and Wales coronial cases (2018–2023) shows bromazolam detected in post-mortem blood at concentrations ranging from 10–2000 ng/mL often alongside other depressants. There is no established “safe” level.
Bromazolam in Wales: WEDINOS Data, Public Health Wales, and Drug Market Trends
WEDINOS (Welsh Emerging Drugs and Identification of Novel Substances) is Wales’s national public drug testing service, funded by Public Health Wales. This testing system enables members of the public and venues to submit samples and receive anonymous analysis and timely and accurate information about the illicit drugs market. The service enables members of the public to receive substance analysis, which may help reduce the risk of accidental overdose. WEDINOS provides timely and accurate information regarding the chemical profile of samples, which is used by substance misuse services and the public.
Key statistics from recent years show the scale of counterfeit and adulterated substances in Wales:
Year | Community Samples Submitted | Mismatch Rate |
|---|---|---|
2022–23 | Over 7,000 | 39–40% |
2023–24 | 7,032 | 42% |
WEDINOS reported that 39% of samples submitted did not contain what the buyer expected, which is an increase from 35% in the previous year. Public Health Wales also reported that 42% of the samples tested by WEDINOS were counterfeit pharmaceutical products or illicit drugs containing substances different from those intended by the purchaser.
Diazepam was the most commonly purchased substance in 2023–24 with 1,532 samples submitted. However, more samples—nearly half (about 48%)—contained no diazepam at all. Bromazolam was the third most commonly identified drug with 616 identifications but was declared as the intended substance only 8 times. Notably, 75 samples submitted as diazepam were found to contain bromazolam or a highly potent synthetic opiate known as nitazene, either on its own or combined. This highlights how purchase intent is often undermined, as individuals believe they are buying diazepam but instead receive bromazolam or nitazene. Individuals purchasing drugs online often receive counterfeit medications that do not contain the expected substances, which increases the risk of accidental overdose.
Tablets submitted as diazepam often contained:
Bromazolam alone
Bromazolam mixed with other benzodiazepines
Bromazolam combined with nitazene-type synthetic opioids
The unpredictability of online drug purchases and counterfeit drugs leads to a greater risk and serious implications for users, including a heightened risk of accidental overdose. Nitazenes, in particular, are sometimes encountered in a yellow powder form, which can mislead users into thinking they are purchasing a different drug.
In South Wales and Gwent between December 2023 and February 2024 there were poisoning clusters which prompted joint responses from the ambulance service, local drug services and Public Health Wales. Benzodiazepines were the most commonly identified class for the sixth year running with 22 variants detected—up from 20 in the previous five years of benzodiazepines surveillance.
Health Risks of Bromazolam: Potency, Overdose and Poly-Drug Use
The main risks of bromazolam come from unknown substances in tablets, higher potency than legitimate pharmaceutical products like diazepam, and common use with other depressant drugs. This creates a risk to people’s health across Wales, especially as the unpredictability of counterfeit drugs makes them particularly dangerous and increases the risk of accidental overdose. The presence of counterfeit or adulterated substances in illicit drugs leads to a heightened risk of harm, as users cannot be sure of what they are taking.
Acute effects at higher doses include:
Deep sedation, confusion and memory blackouts
Slow breathing and reduced heart rate
Increased risk of accidents, injuries and vulnerability
Overdoses in Wales involve benzodiazepines almost always involve multiple substances. Post-mortem data shows co-findings often include cocaine, pregabalin, methadone and other designer benzodiazepines. The median age of Welsh benzodiazepine related deaths is 43, 76% are male.
Cognitive and mental health impacts include impaired judgement, increased risk of high-risk behaviours and possible worsening of anxiety, depression or suicidal thinking during withdrawal. Regular use leads to tolerance and physical dependence, withdrawal symptoms are similar to other benzodiazepines—anxiety, insomnia, tremor and seizures. Withdrawal from high-dose illicit benzodiazepines requires professional support.
“Sold as Diazepam”: Substitution, Counterfeit and Adulterated Substances, and Synthetic Opioids
Common counterfeit tablet features reported to WEDINOS include:
Blue tablets stamped to look like 10 mg diazepam
Inconsistent strength between tablets in the same batch
Visible differences in press quality or colour
WEDINOS substitution patterns show tablets containing bromazolam alone, bromazolam plus other benzodiazepines or—critically—bromazolam with nitazene-type synthetic opioids. Nitazenes are many times stronger than oxycodone or morphine. Because users can’t tell by appearance or taste what’s in a pill, someone taking what they think is a typical diazepam dose may get a much stronger and longer acting benzodiazepine with or without hidden opioids. The issue of wales involved benzodiazepines is particularly concerning, as Wales has seen a rise in misuse and overdose deaths linked to counterfeit and synthetic benzodiazepines, often sourced from illegal online pharmacies.
In 2021, there were 61 drug misuse deaths in Wales involving benzodiazepines, highlighting the dangers associated with these substances.
Health experts warn this substitution has been linked to fatal and non-fatal poisoning episodes in several Welsh health boards prompting multi-agency harm reduction response involving Public Health Wales, WEDINOS, ambulance services and substance misuse services.
Harm Reduction: Appropriate Harm Reduction Information and Practical Advice for People Using Benzodiazepines in Wales
The safest option is not to use illicit benzodiazepines. However for those who may continue to use, appropriate harm reduction information can reduce the risk of harm.
Dosage and frequency:
Don’t take large doses or multiple tablets at once when contents are unknown
Start with a much smaller amount and wait at least 2 hours before considering more
Don’t assume one street “Valium” is 10 mg diazepam
Avoid poly-drug use: Combining bromazolam with heroin, methadone, buprenorphine, nitazenes, alcohol or gabapentinoids is the main cause of benzodiazepine related deaths in Wales.
Overdose risk-reduction:
Use with others present; ensure at least one person remains sober
Avoid risky environments (water, heights, driving)
Recognise overdose signs: very slow breathing, blue lips, can’t wake, gurgling sounds—call 999 now
Naloxone: Naloxone reverses opioid effects but not benzodiazepines. However it can save lives when hidden opioids (such as nitazenes) are present in counterfeit drugs. In 2024, 8,229 take-home naloxone kits were distributed in Wales—a 22.3% increase. Sample providers, services working with night time economy venues and community pharmacies can supply naloxone.
WEDINOS: People in Wales can submit samples to WEDINOS anonymously for laboratory analysis. Results including bromazolam or nitazenes are published online with harm reduction information to help individuals and services respond to higher-risk batches. WEDINOS encourages behaviour change by providing information that helps people make safer choices. Services concerned with substance misuse rely on WEDINOS data to inform harm reduction strategies and public health responses.
