Synthetic Opioids

Synthetic opioids, a group of substances designed to mimic the pain-relieving properties of natural opioids, have recently garnered significant attention due to their potential for abuse and fatal overdoses. Originating from a desire to create effective pain management solutions, these drugs interact with the brain’s opioid receptors, much like their natural counterparts derived from the opium poppy.

However, the landscape of synthetic opioids has evolved, with some variants displaying potencies far surpassing those of traditional opioids like heroin and morphine. Nitazene opioids, for instance, can be synthesised from easily available precursors, posing a high overdose risk similar to heroin. Meanwhile, piperidine benzimidazolone opioids are also noted for their potent, heroin-like effects and associated overdose hazards.

Recognising the escalating danger, the United Kingdom has moved to classify certain synthetic opioids as Class A drugs under the Misuse of Drugs Act of 1971, a decision spurred by the Advisory Council on the Misuse of Drugs (ACMD). This classification aligns with the treatment of other potent opioids and includes drugs with no known legitimate medical use.

The ACMD’s approach, inspired by the German system, aims to future-proof legislation by encompassing both known and predicted harmful variants of these substances. This proactive stance is crucial in a landscape where new synthetic opioids continually emerge, often circumventing existing legal controls.

The UK’s inclusion of drugs like Butonitazene, Flunitazene, and several others in the Class A category underscores the severity of the threat these substances pose. Under the revised legislation, possession and intent to supply these drugs will carry severe penalties, reflecting their high potential for harm.

Globally, the misuse of synthetic opioids has led to significant health crises, with the World Health Organisation (WHO) estimating that opioids were responsible for the majority of the 600,000 drug-related deaths in 2019. The rising fatalities underscore the urgent need for comprehensive strategies to address this growing public health challenge.

In conclusion, the evolving landscape of synthetic opioids presents a complex challenge. While these drugs were originally developed for legitimate medical purposes, their potent effects and ease of synthesis have led to widespread misuse and significant public health concerns. Governments and health organisations worldwide are now grappling with finding effective measures to control these substances while ensuring they remain available for legitimate medical use​.

Synthetic opioids are man-made drugs designed to emulate the effects of natural opioids like opium or heroin. However, they often prove to be much more dangerous, with a higher potential for deadly outcomes. These substances are primarily categorised as Class A drugs in the United Kingdom, indicating their high potential for abuse and the severe legal penalties associated with their possession and distribution.

In medicinal contexts, synthetic opioids are available in various forms, including pills, capsules, patches, and injectable solutions. They are used for pain relief and as anaesthetics. Illegally produced synthetic opioids, on the other hand, are often found in forms like pills or powder, frequently mixed with other substances like heroin. This illegal production and distribution significantly increase their risk profile, as they may be contaminated or mixed with other harmful substances to increase bulk and profitability.

The methods of using synthetic opioids are similar to natural opiates, including injection, sniffing, swallowing, or inhalation. Their effects range from pain relief and a sense of well-being to relaxation and, in high doses, loss of consciousness. However, their use carries significant health risks, notably the suppression of normal breathing, which can lead to respiratory arrest and potentially fatal outcomes. Naloxone is an antidote available for opioid overdoses, underscoring the critical need for awareness and preparedness in dealing with these substances.

The UK’s stance on synthetic opioids is clear, with strict penalties in place for possession and distribution. Possession of synthetic opioids can lead to up to 7 years in prison while supplying them can result in life imprisonment and an unlimited fine. This legal framework reflects the serious public health threat these substances pose and the government’s commitment to mitigating their impact on society​​​​​​​​​​​​​.

• Fentanyl: These include a range of synthetic opioids many times more potent than heroin.
• Nitazenes: A newer group of synthetic opioids known for their simplicity of production and high potency.
• Morphine Derivatives: Man-made drugs similar to morphine but modified to enhance potency or reduce side effects.

Effects of Synthetic Opioids

Physical Effects

Synthetic opioids bind to and activate opioid receptors in the brain, leading to pain relief. However, they also suppress normal breathing, and high doses can lead to respiratory arrest, often fatal. Users may also experience side effects like sweating, itching, nausea, and vomiting.

Psychological Effects

These drugs can induce feelings of euphoria, relaxation, and well-being. They may also cause drowsiness or sleepiness, especially at higher doses. Some users report a sense of tranquillity or detachment from reality.

Short-term and Long-term Effects

• Short-term: Immediate effects include significant pain relief, a sense of euphoria, and sedation. In some cases, especially when used inappropriately, they can lead to respiratory depression, which is potentially life-threatening.
• Long-term: Prolonged use can lead to tolerance (needing more of the drug to achieve the same effect), physical dependence, and addiction. Chronic users are at risk of various health issues, including respiratory problems, cognitive impairment, and mental health disorders.

The rise in synthetic opioid misuse has prompted significant legal and health responses. In the UK, the reclassification of these substances as Class A drugs reflects a recognition of their danger. Medicinally, synthetic opioids remain vital for pain management, but their illicit production and misuse continue to pose serious public health challenges. Addressing this crisis requires a multifaceted approach involving stringent regulation, public education, and access to treatment for those struggling with addiction.

The administration of synthetic opioids varies, with each method having unique implications for the user, particularly in terms of onset, intensity, and duration of effects.

Oral Consumption

• Oral intake is the most common method for medically prescribed synthetic opioids. These drugs are usually taken as pills or capsules and are absorbed through the gastrointestinal tract into the bloodstream. This method is considered relatively safe when prescribed, but it also has the potential for misuse. The liver plays a key role in metabolising these drugs, which can affect their potency and duration of action.

Transdermal Patches

• Transdermal patches are used for continuous, controlled medication delivery over a period, typically for chronic pain conditions. The drug is absorbed through the skin, providing steady pain relief. This method reduces the risk of overdose and misuse compared to oral consumption.

Intravenous Injection

• Intravenous injection delivers the drug directly into the bloodstream, providing immediate and potent effects. This method is usually reserved for hospital settings. However, the illicit use of synthetic opioids through injection is dangerous and increases the risk of overdose, infection, and transmission of diseases due to needle sharing.

Intramuscular and Subcutaneous Injection

• These methods involve injecting the drug into the muscle or under the skin. While slower than intravenous administration, they provide a more prolonged release of the drug into the bloodstream. This method is less common but may be used in certain medical situations.

Intranasal Use

• Some synthetic opioids can be administered intranasally, where the drug is absorbed quickly through the mucous membranes of the nasal passages. This method is less common for prescribed opioids but may be seen in the misuse of certain synthetic opioids.

Rectal Administration

• Although less common, rectal administration (suppositories) can be used when patients cannot take oral medications or in certain emergency medical situations.

Inhalation

• Inhaling vaporised synthetic opioids is rare and usually associated with illicit use. It poses significant risks to respiratory health and increases the likelihood of overdose due to rapid absorption into the bloodstream.

Understanding the various methods of administering synthetic opioids is crucial for healthcare providers and patients alike. It helps in tailoring pain management to individual needs while minimising the risks of misuse, addiction, and other adverse effects. Each method comes with its own set of benefits and risks, and the choice depends on the specific medical situation, the type of opioid, and the intended therapeutic outcome.
