Amphetamines are stimulant drugs, which means they act to speed up heart rate and breathing. Some types of amphetamines are legally prescribed by doctors to treat conditions such as attention deficit hyperactivity disorder (ADHD), narcolepsy and Parkinson’s. Other types of amphetamines such as speed are produced and sold illegally. The more potent form is crystal methamphetamine (ice), speed now mostly contains methamphetamine of varying purity. Speed aka amphetamines come in various forms including powder, tablet, paste (ox-blood) and crystal.

Half life: Even though the apparent effects of the drug wear off after 6 hours, the drug is still active in your system for up to 12-14 hours after you have taken it. Try to remember this if using other substances or redosing.


Roadside Police: Roadside saliva tests do look for speed (amphetamines) and other substances can be detected that might have been cut into your speed. It is illegal to drive under the influence of any illicit drugs, including speed and any driver may be subject to a roadside behavioural impairment test. Wait at least 72 hours before driving.

Workplace: Urine: 1-4 days Hair: Up to 90 days Blood: 12 hours



Effects vary from person to person. Check out our table below that has listed the potential physical, psychological and emotional effects.


Taking drugs is never without risk. In an unregulated market it’s impossible to know the purity or dose of any drug.  ‘Dose’ depends on the form a drug is in (liquid, powder, pill, crystal) and how you have it (snort, eat, inject).

Depending on purity, amphetamine doses will vary. Prescription based amphetamines, like Adderall contain their own prescribed dosage information.
A standard recreational dose of snorted amphetamine is between 10mg and 40mg.

Compound Dose (mg)
Low  Moderate  Strong  Heavy 
Amphetamine (Speed) 
Snorted  6-15 15-30 30-50 50+
Oral  5-10 10-25 25-50 50+
Snorted 3-5 5-10 10-20 20+
Oral  3-5 5-15 15-30 30+


Carrying speed and paraphernalia (e.g. injecting/snorting/plugging equipment) puts you at risk of criminal charges including trafficking, even if you don’t deal. As of May 5 2024 Queensland introduced police drug diversion for minor drug possession offenses involving personal use amounts of some drugs. ‘Personal amount’ quantity of Speed is anything 1.0g/ml or under & non-prescribed ADHD medication can be any quantity however the Police Officer must believe they are all yours for personal consumption and not for dealing. Know your local laws e.g. Drugs Misuse Regulation 1987 (QLD), Police Powers and Responsibilities Regulation 2012 (QLD), the Drugs Poisons and Controlled Substance Act 1981 (Vic).

‘Pill Testing’/Drug Checking: Lab-quality testing is advised for the best results and available in the states of ACT & QLD. These services offer free and anonymous drug checking. DIY reagent testing is also an option. Marquis and Mandelin give a reaction. Mecke and Robadope do not give a reaction. This information can be used to cross-reference results.  See photos of testing results here > verbinding.110110

  • Psychotic episodes and/or mania
  • Delusions
  • Excited Delirium Syndrome


  • Start with a small amount as you don’t know how strong it will be.
  • Remember to eat well then wait 20-30 minutes before using.
  • Be aware of overheating and try to cool down & chill out regularly.
  • Remember to keep your fluids up but don’t drink too much – 1 cup of water (250ml) p/h  when resting & up to 500ml p/h when dancing or active.


  • Crush the powder so there’s no crystals (sparkles can cause little cuts).
  • Snort water before and after to avoid damaging the protective lining in your nose 
  • Use your own clean straw/spoon for snorting to prevent the risk of infection, ‘Snorter’ warts (HPV), or blood borne virus transmission  (‘BBV’ e.g. hepatitis C) via microscopic amounts of blood
  • Do not use money – it is covered in bacteria. 
  • Repeated snorting can damage the membranes of the nose leading to possible permanent damage to the septum (the middle bit). It can lead to frequent nosebleeds and runny nose, loss of smell, and problems swallowing
  • Switch nostrils regularly and give your nose a break.


  • Ingesting amphetamines results in slightly different effects to snorting or injecting. If taken as a ‘parachute” (wrapping a dose in a cigarette paper) the effects take longer to feel and the experience will last longer. You can also break the pills to have lower doses and swallow with water.
  • Gumming is another less common way of doing it. A small amount is applied on the inside of the lips or gum. This can damage your gums and lips.

SHELVING (dry)/ PLUGGING (wet mix)

  • Use lubrication to avoid tearing the skin
  • Use a condom or latex/vinyl glove to avoid internal scratches
  • Wash your hands before and after using
  • Find a discreet and safe place to do it
  • Dispose of used condom / glove responsibly.


  • Avoid Blood Borne Viruses ‘BBVs’ (eg. Hepatitis C, HIV) by using new & sterile syringes & equipment.
  • Use sterile water to mix up.
  • Wash your hands thoroughly before and after, you can also use an alcohol swab to clean your fingertips.
  • Alcohol wipes can reduce the risk of skin infections if they are used correctly. For maximum effect, swab once, in one direction on the injection site, and leave to dry naturally.
  • Dispose of syringes & equipment responsibly in a yellow disposal bin, all NSPs have bins available.


  • Physical and Psychological Dependency 
  • Loss of appetite, weight loss
  • Poor health and nutrition
  • Lowered resistance to illness
  • Poor dental health
  • Impotence
  • Psychosis
  • Fatal kidney and lung disorders
  • Possible brain damage and/or psychological problems
  • Stroke
  • Vein collapse or infection (long term injecting)
  • Blood Borne Virus and liver damage (long term injecting)


High doses and frequent heavy use can also create an ‘amphetamine psychosis’, characterised by paranoid delusions, hallucinations and out of character aggressive or violent behaviour. These symptoms usually disappear a few days after the person stops using amphetamines and regular sleeping patterns returned.


  • After 2-3 hours remember to keep your electrolytes up
  • If you’re finding it hard to eat try a smoothie or a soup
  • Sleep! Or lay down and cover your eyes during a 24-hour period. Many of the negative effects of ice are caused by sleep deprivation.
  • Take good care of your teeth.
  • Factor in and plan recovery time before you need to do another activity.


Environmental / Weather: As a stimulant, speed will increase your body’s temperature and breathing rate, and make it more difficult for your body to regulate itself. Taking stimulants in hot indoor/outdoor environments can be deadly or lead to multi-organ failure.   

It is not recommended to use speed if you have or are at risk of:

  • Heart Problems
  • Anxiety
  • Psychotic disorders
  • Schizophrenia
  • Respiratory problems
  • Heart problems
  • Pregnant/ Breastfeeding

Drug combinations

Polydrug use has many possible outcomes. What could be fun for one person could be dangerous for another. We do not endorse any of these combinations and recommend you proceed with caution.

Unsafe combinations

  • Tramadol – Increase of risk of seizures
  • MAO-B inhibitors – can increase the potency and duration of phenethylamines unpredictably.
  • MAO-A inhibitors – with amphetamine can lead to hypertensive crises, psychosis, agitation and aggression.

Cautionary combinations

  • 2C-T-x – Stimulants increase anxiety levels and the risk of thought loops which can lead to negative experiences. In extreme cases, they can result in severe vasoconstriction, tachycardia, hypertension, and in extreme cases heart failure.
  • DXM (cough syrup) – Both substances raise heart rate, in extreme cases, panic attacks caused by these drugs have led to more serious heart issues.
  • Psychedelics (LSD, Psilocybin) – can increase anxiety levels and risk of thought loops leading to negative experiences
  • Stimulants (Cocaine, Methamphetamine, Caffeine etc) – Combination of stimulants will increase the strain on the heart risking stroke, as well as potentially causing anxiety and greater physical and mental discomfort.
  • Alcohol – Stimulants reduce the sedative effects of alcohol which can lead to excessive drinking and the risks associated with that.
  • GHB/GBL– Stimulants increase respiration rate allowing a higher dose of sedatives. If the stimulant wears off first then the sedative may overcome the patient and cause respiratory arrest.
  • Opioids – Stimulants increase respiration rate allowing a higher dose of sedatives. If the stimulant wears off first then the sedative may overcome the patient and cause respiratory arrest
  • Ketamine – No unexpected interactions, though likely to increase blood pressure but not an issue with sensible doses. Moving around on high doses of this combination may be ill advised due to risk of physical injury

Low risk effects

  • Nitrous – These drugs can sometimes work together to cause an effect greater than when taken on their own.
  • MDMA – Amphetamines increase the neurotoxic effects of MDMA
  • Benzodiazepines – Both can dull the other substances effects, so if one wears off before the other it’s possible to overdose due to the lack of counteraction so be careful! Also using a depressant drug to help with the come down effects may result in a cycle of dependence on both types of drugs.
