Doctors can legally prescribe some amphetamines to treat conditions such as Attention Deficit Hyperactivity Disorder (ADHD). Other amphetamines, including speed and ice, are produced and sold illegally.
Speed comes as a powder, tablet or capsule and can be swallowed, injected, smoked or snorted. It’s also known as fast, uppers, louee and whiz.
Speed targets your brain’s ‘reward system’ and can make you feel happy, confident and more energetic. Many users crave these feelings, which can lead to addiction. Find out about the physical health effects of speed.
Mental health issues
There are lots of mental health issues linked to using speed. Most of them are associated with coming down after taking speed, or long-term use. They include:
- depression and anxiety
- difficulty sleeping
- paranoia, hallucinations and confusion
- irritability, mood swings and panic attacks
- problems with memory and concentration
- violent behaviour
High doses and frequent use can create amphetamine or speed psychosis. It’s very similar to paranoid schizophrenia with symptoms of hallucinations, and out-of-character violent and aggressive behaviour.
Speed binges are also linked to reckless and aggressive behaviour.
As well as physical and mental health issues, users risk social, work and financial problems. Regular use of speed can cost a lot, and have a negative impact on how your do your job and interact with family and friends.
