Methamphetamine is considered a far more powerful stimulant than amphetamine sulphate, partly because the effects can last for up to twice as long, and partly because the effects are also more psychological and less ‘physical’. It is often claimed to be the ‘sexiest’ kind of stimulant. Some men report methamphetamine produces more powerful orgasms and erotic experiences. Some claim that they get better erections, although others can find it difficult to get or keep a normal erection.

Minor side effects include.
  • blurred vision
  • Dry mouth, lips, and eyes
  • Muscular tension.
  • Side effects include.
  • Increased heart, blood pressure and body temperature.
  • Paranoia.


Come downs include.
  • Tiredness
  • Confusion
  • Hunger
  • Depression
  • Irritability
  • Lacking concentration
  • Wallowing in self-pity.


The after-effects on the body include.
  • Jaw ache
  • Sensitivity to light
  • Cracked lips.
  • Dry or spotty skin
  • Upset stomach.
  • Dizziness
  • Aching muscles.


Following a session/binge of several days, users may fall asleep suddenly ‘crash’ and stay asleep for 24 hours or longer.
The only way to avoid any risk of harm from methamphetamine is not to use it. People who should particularly avoid methamphetamine are those with psychiatric problems, respiratory complaints (e.g. asthma), and heart conditions (e.g. palpitations).

  • Stimulant drugs raise your body temperature. Heatstroke can be a killer, particularly (but not exclusively) if you are dancing in a hot club. Sip water regularly (about a pint an hour) and cool down by resting, dabbing cool water on your face and getting some fresh air.
  • Rinsing your nose with water afterwards, may lessen damage to the inside of your nose. Straws and banknotes should not be shared as this can spread blood borne viruses (Hep B, Hep C, HIV).
  • Sharing any injection equipment risks spreading blood borne viruses. Clean injection equipment and advice on safer injection is available from needle exchanges.
  • Most people find that stimulant-induced paranoia fades away when they stop using. Drug induced psychosis is usually short-lived and much easier to treat than other psychotic illness. However, if your drug use has become a problem or you are worried about your mental health there are free, confidential, non-judgemental services that can help.
  • It is worth making a pact with people you use with to look after each other in an emergency and ring for an ambulance. Look after others the way you would want them to look after you.
  • Using sleeping pills, alcohol or other drugs to get to sleep or avoid your come-down can become a habit that means your life starts to revolve around drugs.
  • Always practice safer sex and be clear with others about where your boundaries are.


Smoking methamphetamine is regarded as the most euphoric and habit-forming method of use. If you are experiencing problems, there is help available.

Long term risks:

  • Like other powerful stimulant drugs, methamphetamine can trigger psychotic illness (delusions, paranoia, hallucinations, hearing ‘voices’ etc.).
  • Depression (suicidal thoughts etc.) may alternate with periods of euphoria.
  • Heavy use, or prolonged moderate use, may damage the cardiovascular system (heart), the immune system and/or central nervous system.
  • Constant strain on the cardiovascular system may lead to high blood pressure, irregular heart rhythm and even stroke.
  • Crystal meth has a high potential for abuse and dependence.

Short term risks:

  • There is a risk of heart attack or stroke from using any powerful stimulant drug, although fatal overdosing with methamphetamine is fairly rare.
  • Methamphetamine can interact with certain HIV medications which can boost the amount of meth in the bloodstream to a dangerous level. This increases the risk of overdose or other serious harm.
  • There are specific risks involved in injecting crystal meth such as damage to veins and soft tissue as well as risks of blood borne viruses if equipment is shared.
  • ‘Booty bumping’ can cause irritation and tissue damage and increase the risk of Sexually Transmitted Infections (STI’s).
  • Some men find it difficult to maintain their normal boundaries as the desire to have sex is very strong and safer sex can seem less important in the moment.
Central nervous system stimulant.

Methamphetamine is a stimulant drug that can appear as a white or off-white powder (crushed crystals) as white or colourless (cocaine sized) crystals, or as a pill. Crystal meth can be made up of crystals up to several inches long and range in colour from clear to bluey white. Crystal meth is to methamphetamine, what ‘crack’ is to cocaine. In the UK it is mostly used in the Chemsex scene.
  • Crystal meth is usually smoked in a glass pipe as the crystals will dissolve in water (and melt if you hold them) so cannot be smoked in a water pipe.
  • It can be snorted in powder form if the crystals have been finely crushed.
  • It can be mixed with water and injected (‘slammed’).
  • Crystal meth is sometimes mixed with water and syringed inside the anus known as ‘booty bumping’.
If the drug is snorted - a razor blade will be used to chop it on a hard level surface such as a mirror or a sheet of glass or a tile. A tube or rolled banknote will be used as a 'pipe'.
If injected: syringe and needle, water, tourniquet.
If smoked: matches and tinfoil.
Methamphetamine (also known as methylamphetamine) appears in various forms and has numerous trade, chemical and street names. If you purify methamphetamine hydrochloride you end up with dextro-methamphetamine hydrochloride, which when dissolved in warm water and allowed to slowly cool, produces a crystalline powder, or much larger crystals known as ‘crystal meth’, ‘ice’, ‘tina’ etc. It is larger made in illicit labs in other countries and imported but is also made in illicit labs in the UK.
Most areas of the UK have 'street agencies' or projects (sometimes called community drug services or community drug teams) which offer a range of services including information and advice, counselling, needle exchanges and sometimes support groups and complementary therapies such as acupuncture. The increase in stimulant use has led to some agencies offering specialist counselling, cognitive behaviour therapy, acupuncture and other alternative therapies and prescribing of anti-depressants, and also possible referral to residential rehabilitation. Some services have extended working hours and may offer weekend support. GPs and possibly the local hospital A&E department can make referrals to specialist drug services as well as general medical services, information and advice often in partnership with a drug agency or Drug Dependency Unit.

Parents & other relatives

Drug agencies also provide lots of advice and support to parents of people using these drugs. Many street agencies can provide relative support groups or counselling for family members, partners etc.
