Sometimes a person may experience a hangover effect that can last up to three days.

The effects of amphetamines will vary from person to person depending on characteristics of the:

As methamphetamine is more potent than dexamphetamine, users are likely to experience more severe side-effects.

The effects of methamphetamine include anxiety, depression, paranoia, aggression and psychotic symptoms. Methamphetamine also increases the risk of mental health problems, so people with an existing mental health condition should be even more cautious about using this drug.

There are also dangerous effects associated with the method of use. Snorting can damage the fragile mucous membrane in the nasal passages. It produces burns and sores on the membranes that line the interior of the nose. Injecting amphetamines can result in blocked blood vessels that can cause major damage to the body’s organs, such as inflamed blood vessels and abscesses, blood poisoning, bacterial infections which may damage the heart valves, vein collapse, infection at injection site, bruising or more serious injuries if users inject into an artery or tissue.


Overdose can cause:

  • Strokes
  • Heart failure
  • Seizures
  • Death
