  • you’re curious about what amphetamines do to you
  • you want to know about the negative effects of amphetamines.

What are amphetamines?

  • methamphetamine (or ‘meth’)
  • speed
  • ice

What do amphetamines do to you?

Taking amphetamine can make you feel:

  • awake, energised, confident, happy or euphoric
  • more talkative, or agitated
  • aggressive
  • confused (scattered or sketchy)
  • paranoid, anxious or depressed.

Amphetamines can also affect you physically by:

  • making you clench your jaw a lot
  • making you sweaty
  • causing hot and cold flushes
  • causing headaches, dizziness and restlessness
  • increasing your heart rate or making your heart beat irregularly
  • making your skin pale
  • making you sick if you mix them with other drugs or alcohol.

In the long run, taking amphetamines regularly can:

  • lead to anxiety, depression and sleep issues
  • create constant paranoia or confusion
  • lead to psychosis
  • make you violent for no apparent reason
  • increase your blood pressure
  • lead to an amphetamine addiction.

How do I know if I’m addicted to amphetamines?

Amphetamine drugs are highly addictive, and you can develop an unhealthy relationship with them after only one or two uses. Here are some signs that amphetamines are becoming a problem:

  • You think all the time about taking amphetamines.
  • You get anxious if you think you won’t be able to get any.
  • You need to take amphetamines to feel ‘normal’.
  • You need amphetamines to start the day.
  • You feel like your perception of reality is starting to change.
  • Amphetamines are causing issues with your friends and family.
  • You’re doing things that are illegal or out of character to get amphetamines.

If you recognise any of the above signs in yourself, it’s important that you get help. You can talk to a doctor, a nurse, or a mental health worker such as a counsellor or a psychologist. Try using the ReachOut NextStep tool to get you connected with a service that’s right for you.
