What are Emerging Drugs?

In recent years, many ‘new’ drugs have arrived on the market. These are often advertised as ‘legal highs’ , despite the fact that in many cases they are not legal. These substances are also marketed as ‘synthetic drugs’, ‘party pills’, ‘research chemicals’, or ‘plant food’, and are often used instead of other illegal drugs. They are sometimes sold in stores or online and marketed as ‘legal’ and ‘safe’. However, many contain ingredients that are actually illegal and can be very dangerous.

Continual changes to these products make it hard to know what they contain, what the effects will be and what potential impact they make have on users in the short and long term. Current substances include:

One pill (or package) may contain a mixture of different things. New drugs are sold under many other names, including 'Infinity', 'Benzo Fury' and 'Diablo'. There are many different names and these change frequently. Users can never be sure what they're getting as the packaging doesn't guarantee what's inside.

You never know what's in a pill

What are the effects?

 Taking these is like a roll of the dice — they haven't been around long enough to know what the immediate risks are or what might happen in the long run to people who use them. However, it is known that a small number of people have died from using some types of new drugs.

Effects of new drugs vary, but may include:


  • Increased heart rate and body temperature
  • Enlarged pupils
  • Feeling of euphoria (a 'high')
  • Twitches and tremors
  • Aggressive behaviour
  • Anxiety and panic attacks
  • Nausea and vomiting
  • Dizziness and headaches
  • Confusion
  • A 'comedown' (see glossary of terms)
  • Insomnia
  • Hallucinations (seeing or hearing things that aren't really there)
  • Overdose
  • Serotonin syndrome (see glossary of terms)
  • Paranoia and psychosis
  • Seizures.

Long Term

Early information from research suggests that these new drugs may lead to a range of problems including:

  • Dependence (addiction)
  • Memory problems
  • Paranoia (feeling extremely suspicious and frightened)
  • Psychosis (see glossary).
