What are New Psychoactive Substances?

NPS

New Psychoactive Substances

New psychoactive substances (NPS) are drugs which were designed to replicate the effects of illegal substances like cannabis, cocaine and ecstasy whilst remaining legal – hence their previous name ‘legal highs’.

NPS began to appear in the UK drug scene around 2008/09. They fall into four main categories:

Synthetic cannabinoids – these drugs mimic cannabis and are traded under such names as Clockwork Orange, Black Mamba, Spice and Exodus Damnation. They bear no relation to the cannabis plant except that the chemicals which are blended into the base plant matter act on the brain in a similar way to cannabis.

Stimulant-type drugs – these drugs mimic substances such as amphetamine, cocaine and ecstasy and include BZP, mephedrone, MPDV, NRG-1, Benzo Fury, MDAI, ethylphenidate.

‘Downer’/tranquiliser-type drugs – these drugs mimic tranquiliser or anti-anxiety drugs, in particular from the benzodiazepine family and include Etizolam, Pyrazolam and Flubromazepam.

Hallucinogenic drugs – these drugs mimic substances like LSD and include 25i-NBOMe, Bromo-Dragonfly and the more ketamine-like methoxetamine.

Much media attention is given to announcements that significant numbers of ‘new drugs’ have been identified. This can be misconstrued as suggesting that all these new drugs are as different from each other as cannabis is from heroin is from cocaine. However, invariably, any new drug identified, will fit into one of the above categories.

NPS are sold online and until recently were sold in shops. The drugs come in brightly coloured packaging under a variety of brand names. The packaging may describe a list of ingredients but it’s impossible to be sure what’s inside and the contents of one branded package could change from week to week.

Effects

The effects of NPS vary significantly from drug to drug and, compared to more traditional drugs, we have relatively little information on them. However, there is a growing body of evidence to demonstrate the potential short and long-term harms associated with their use. There have been hospitalisations and deaths linked to NPS.

The Scottish Drugs Forum carried out a survey of drug services in 2013 which summarised some of the key reported harms during intoxication and comedown:

  • Overdose and temporary psychotic states and unpredictable behaviours;
  • Attendance at A&E and some hospital admissions;
  • Sudden increase in body temperature, heart rate, coma and risk to internal organs (PMA);
  • Hallucination and vomiting;
  • Confusion leading to aggression and violence;
  • Intense comedown that can cause users to feel suicidal.

Use was also associated with longer term health issues:

  • Increase in mental health issues including psychosis, paranoia, anxiety, ‘psychiatric complications’;
  • Depression;
  • Physical and psychological dependency happening quite rapidly after a relatively short intense period of use (weeks)

The law

While many of these drugs were once legal, with the advent of the Psychoactive Substances Act it is now illegal to produce, supply, or import them for human consumption – including for personal use. Possession for personal use is not an offence, unless in prison.

The Psychoactive Substances Act received Royal Assent on 28 January 2016 and came into force on 26 May 2016.

The act:

  • makes it an offence to produce, supply, offer to supply, possess with intent to supply, possess on custodial premises, import or export psychoactive substances; that is, any substance intended for human consumption that is capable of producing a psychoactive effect. The maximum sentence will be 7 years’ imprisonment
  • excludes legitimate substances, such as food, alcohol, tobacco, nicotine, caffeine and medical products from the scope of the offence, as well as ‘poppers’ and controlled drugs, which continue to be regulated by the Misuse of Drugs Act 1971
  • exempts healthcare activities and approved scientific research from the offences under the act on the basis that persons engaged in such activities have a legitimate need to use psychoactive substances in their work
  • includes provision for civil sanctions – prohibition notices, premises notices, prohibition orders and premises orders (breach of the 2 orders will be a criminal offence) – to enable the police and local authorities to adopt a graded response to the supply of psychoactive substances in appropriate cases
  • provides powers to stop and search persons, vehicles and vessels, enter and search premises in accordance with a warrant, and to seize and destroy psychoactive substances

Some synthetic cannabinoids like Spice are controlled as Class B substances under the Misuse of Drugs Act. Offences for Class B drugs are:

  • Possession – Maximum sentence – 5 years/fine/both
  • Possession With Intent To Supply – Maximum sentence – 14 years/fine/both
  • Supply (including being concerned in supply, conspiracy to supply, aggravated supply and offer to supply) – Maximum sentence – 14 years/fine/both
  • Production – Maximum sentence –  14 years/fine/both

However, maximum sentences are rarely used. See this page from Release for more detailed information on sentencing.

Review of the Psychoactive Substances Act 2016
In November 2018 the Home Office published a review of the Act that sought to measure changes in outcomes before and after its implementation and thereby provide an indication of whether its aims are being achieved.

Prevalence

According to 2018 statistics from the Home Office on drug use in England and Wales in 2018:

  • Use of NPS has not changed in the last year. Approximately 0.4 per cent of adults aged 16 to 59 had used NPS in the last year (equivalent to around 121,000 adults). While this was the same level as in the 2016/17 CSEW, it was lower than the 0.7 per cent found in the 2015/16
    survey
  • As in previous years, around half of all NPS users were aged 16 to 24. In the last year 1.2 per cent of adults aged 16 to 24 used NPS (equivalent to around 70,000 young adults)
  • People who had visited a pub or nightclub, consumed alcohol, or used another drug, were more likely to have used NPS in the last year than those who had not. This was true for young adults aged 16 to 24 as well as the wider 16 to 59 age group.
  • Herbal smoking mixtures were still the most commonly used NPS in the last year, although there was an increase in the use of liquids. A third (33%) of last year users aged 16 to 59 had smoked a herbal mixture on the last occasion that they used NPS. One in four
    (25%) ingested a liquid, which was twice as high as the previous year (12%)
  • NPS were still more likely than other illicit drugs to be obtained from shops and the internet. Around 30 per cent of last year NPS users aged 16 to 59 had obtained the last NPS they used from either a shop (15%) or the internet (15%), compared with 5 per cent for other
    illicit drugs (4% from a shop, 1% from the internet)

New psychoactive substances in Europe: legislation and prosecution — current challenges and solutions, 2016
The European new psychoactive substances (NPS) market has increased at a speed that established drug control laws struggle to match. Various countries have therefore introduced new legal responses to this phenomenon, based either on existing laws that focused on consumer or health protection or medicinal products, or by developing innovative new legislation. In 2014, the Court of Justice of the European Union ruled that substances are not medicinal products if they do not have beneficial effects on human health, thus restricting the use of such laws for NPS control | EMCDDA/Eurojust, Portugal
