Also known as: GHB, GBH, Gabba, Liquid Ecstasy, 'G'
Similar substances: Gamma-butyrolactone (GBL)
What it looks like and how it's taken

Comes in small bottles. Colourless, odourless liquid. Sometimes it also comes in capsule form. Liquid and capsules can be swallowed. It is a common solvent used in products like paint strippers and stain removers.
Immediate effects
GHB and GBL produce essentially the same effects and vary greatly in strength. They both produce a feeling of euphoria and can reduce your inhibitions and make you feel sleepy.
Risks
Short term: Larger doses can cause drowsiness, sickness, disorientation, convulsions, coma and breathing difficulties. Can cause nausea, reduced heart rate, drowsiness, coma, hypothermia, seizures, unconsciousness, coma and death. Due to their effect GHB and GBL have been linked to drug-assisted sexual assault.
Long term: Long term effects are not well understood. Using both GHB and GBL can cause unconsciousness, coma and death. Even experienced users are at risk from death by intoxication.

Effects are those of a stimulant somewhat like MDMA. It may produce euphoria, alertness, talkativeness and feelings of empathy. But also anxiety and paranoid states in some.
Risks
Short term: Severe nosebleeds have been reported after snorting as well as anxiety and paranoia. There is also the risk of over-stimulating the heart and the nervous system, which would increase the chances of having a fit.
Long term: Some reports say it can be compulsive to use and create a state of psychological dependence. It has recently been made illegal in a number of countries due to growing evidence of harms, including a reported possible cause of death in Sweden in 2008.

Methamphetamine is still relatively rare in Ireland.
Immediate effects
Immediately after smoking or injecting, users experience a rush that lasts only a few minutes. Small amounts of methamphetamine can produce euphoria, wakefulness, increased physical activity, decreased appetite and increased respiration. The user may also experience powerful hallucinations.
Risks
Short term: The drug can cause disturbing hallucinations and make the user extremely paranoid. One of the nastier and most common hallucinations is 'speed bugs' or 'crank bugs' where users think bugs are crawling under their skin and go frantic trying to get them out.
Long term: Regular use is linked to lung and kidney disorders. Coming off the drug can lead to severe depression and suicidal urges.
Legal status
Methamphetamine is a form of amphetamine and currently sits within Class A.

Stimulant.
Naphyrone
Also known as: NRG-1, NRG1, Energy-1, Energy1, Rave
Similar substances: Methylone, Methedrone, Amphetamine, Speed, MDMA
What it looks like and how it's taken
Naphyrone is a fine white or off-white/yellow powder – usually snorted like cocaine or swallowed ‘bombed’ in wraps of paper.
Naphyrone is a stimulant drug closely related to ‘cathinone derivatives’ including mephedrone, a group of drugs that are ‘cousins’ of the family of amphetamine compounds which include amphetamine itself (speed), methamphetamine and ecstasy (MDMA), among many others.
When sold over the internet, it was often described as a plant food, research chemicals or bath salts, and not for human consumption.
Immediate effects
Effects are those of a stimulant somewhat like MDMA. It may produce euphoria, alertness, talkativeness and feelings of empathy. But also anxiety and paranoid states in some.
Risks
Naphyrone does not have a long history of use, so there is little evidence of its long term effects or on the risks from using it. However, due to its similarity to other ‘cathinone derivatives’, naphyrone is likely to share the same risks such as anxiety, paranoia, overstimulation of the heart and circulatory system and overexcitation of the nervous system (with the risk of fits).
The high potency of naphyrone by comparison with other cathinones like mephedrone suggests that it is likely to be associated with a higher risk of accidental overdose.
Legal status
Naphyrone was controlled as a Class B drug on the 23rd July 2010 meaning it is illegal to have, give away or sell. Possession can get you up to five years in jail. Supplying someone else, including your friends, can get you up to fourteen years in jail and an unlimited fine.

Also known as: Chicken Yellow, Chicken Fever, Double Stacked, Killer
What it looks like and how it's taken
Usually a white tablet which is unusually thick compared to ecstasy, hence the name 'Double-Stacked'. PMA is swallowed.
Immediate effects
Users report experiencing similar effects to ecstasy although effects last substantially stronger.
Risks
Short term: PMA affects the body's temperature control and as it is stronger than Ecstasy the risk of overheating is much greater. Users require immediate help if they feel their temperature soaring on the dance floor and anyone with a heart condition, blood pressure problems, epilepsy or asthma can have a very dangerous reaction to the drug. Frequent use can also bring on paranoia and depression.
Long term: As PMA is a drug is quite a new drug, long term risks have not yet been established, but it is thought that they are likely to be similar to the risks associated with Ecstasy.
Legal status
Class A.

Stimulant.
Piperazines
Also known as: BZP, Party Pills, Fast Lane, Silver Bullet, Smiley's, Happy Pills, Pep
What it looks like and how it's taken
Piperazines are a broad class of chemical compounds used widely in human and veterinary medicines. The best-known recreational stimulants are BZP (Benzylpiperazine), TFMPP, DBZP and mCPP, which mimic the effects of ecstasy. They are also used in industry to make plastics, resins, pesticides, brake fluid and a variety of materials and products. Some piperazine compounds act as effective worming agents for pets and farm animals. BZP can come in different coloured pill form and is also sold as an off-white powder, in capsules and as a liquid.
Immediate effects
The stimulant effects of BZP are similar to ecstasy but dose for dose BZP is not as potent. Effects can last for 6 – 8 hours. With decreased appetite and sleeplessness. Users often suffer a severe hangover-like reaction that can last for up to 24 hours.
Risks
Short term: Agitation, vomiting, stomach pain, fits, irregular heart rhythms, diarrhoea, allergic reactions and fever have all been reported.
Long term: BZP is a stimulant drug, which makes it particularly risky if taken by anyone suffering from high blood pressure or a heart condition. Perfectly healthy young people can have a fit or heart attack after taking stimulant drugs. And you may not know that you have a pre-existing heart condition. ??Mixing BZP with amphetamines (like ecstasy and speed) and alcohol can be very dangerous. In rare cases users may suffer from serotonin syndrome, which can cause high blood pressure and may be fatal.

Depressant.
Synthetic Cannabinoids
Also known as: Spice
What it looks like and how it is taken
Products like 'Spice' are likely to contain synthetic cannabinoids which is a chemical produced to mimic the psychoactive effects of THC (tetrahydrocannabinol), the active compound in cannabis. Herbal smoking mixtures tend to be a mix of inert plant ingredients that are sprayed with synthetic cannabinoid compounds. There is nothing natural or herbal about these compounds, they are man-made.
Immediate effects
Synthetic cannabinoids mimic the psychoactive effects of THC and so the effects - good and bad - are likely to be very similar to cannabis.
Risks
Short term: The chemical composition and ingredients of herbal products like ‘Spice' are changing all the time, and there are a wide range of possible synthetic cannabinoids that could be used, which is why you can never be sure what you're getting or how it will affect you.
Long term: Regular use of products containing stronger synthetic cannabinoids may increase the risk of later developing psychotic illnesses including schizophrenia.
Experts are concerned that 'Spice' products containing synthetic cannabinoids have the potential to be more harmful than cannabis due to the way they are made and because the compounds present and there potency will be unknown to the user.
Legal status
Synthetic Cannabinoids ('Spice') became a class B drug under the Misuse of Drugs Act 1971 in December 2009.
