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) comes in various forms including powder, tablet, paste (ox-blood) and crystal.

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

Heart Problems, Anxiety, Psychotic disorders, Schizophreni, Respiratory problems, Heart problems



Polydrug use has many possible outcomes. What could be fun for one person could be dangerous for another. We recommend you proceed with caution.


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.


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 etc) - Combination of stimulants will increase the strain on the heart risking stroke.

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.



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

‘Pill Testing’/Drug Checking: Lab-quality testing has been trialed in Australia and is not available as a health service yet but DIY reagent testing is 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.



  • Use around people you trust and somewhere you feel safe.

This resource has been made by people who use drugs for their peers & the wider community. The role of DanceWize is to provide credible & non-judgmental info to promote health & harm reduction. In an unregulated (illegal) market you don’t know the purity or dose of any drug and there is always some risk. You can educate yourself and practise harm reduction to reduce risk. Knowledge is power. #JUSTSAYKNOW
