In this article, we take a closer look at methamphetamine, what it is, how it is used, the side effects of methamphetamine use and more.

What is methamphetamine?

Part of the amphetamine family, methamphetamine – also known as crystal meth, crystal or speed – is a powerful and highly addictive synthetic stimulant drug.

Although it is closely related to amphetamine, the effects of methamphetamine are much more intense, and have a greater effect on the central nervous system.

Its euphoric effects are also similar to cocaine, but longer lasting.

What are the street names for methamphetamine?

Some of the most common street names for methamphetamine include:

  • Meth
  • Crank
  • Speed
  • Shards
  • Crystal

What does methamphetamine look like?

Methamphetamine can come in several forms including crystals, tablets or powder.

How is methamphetamine used?

Recreational drug users swallow, inject or snort methamphetamine.

However, methamphetamine in its purer form (crystal meth) is also smoked.

How do people behave when they take methamphetamine?

Because methamphetamine belongs to the amphetamine family of stimulant drugs, using methamphetamine can make a person feel more alert, energized, and awake.

However, in some people it can cause agitation, confusion and/or aggression.

Long-term methamphetamine use has also been linked to psychiatric problems resembling those associated with schizophrenia, such as paranoia and hallucinations.

It can also cause psychosis, resulting in homicidal or suicidal thoughts.

What are the side effects of methamphetamine use?

Some common physical side effects of methamphetamine use include:

  • Raised blood pressure
  • Increased heart rate
  • Stroke
  • Lung and kidney damage
  • Dental problems including tooth decay and tooth loss (from smoking)
  • Itchy skin leading to severe scratching, infections, and wounds
  • Loss of appetite

Inhibitions may also be lowered in a person using methamphetamine, which can lead to risky behaviors, such as unsafe sex and, in turn, sexually transmitted infections (STIs).

A person who injects methamphetamine is also at an increased risk of overdosing or contracting life-altering infections such as HIV, hepatitis B and hepatitis C. This risk is even greater among users who share needles.

There is also the risk that veins may be damaged, and of abscesses or clots developing.

What happens when you use methamphetamine with other drugs?

Below is an overview of the side effects of using methamphetamine alongside other drugs.

Alcohol

Because methamphetamine is a stimulant drug and alcohol is a depressant, people sometimes use one substance to counteract the effects of the other.

However, this can be dangerous, as the stimulant effects of methamphetamine combined with the depressant effects of alcohol can cause an unpredictable reaction, with serious consequences including increased risk of harm or even death.

Cocaine

Using cocaine and methamphetamine together can greatly increase the risk of heart problems, sleep disturbances and mood swings.

Heroin

Using heroin and methamphetamine together can increase the risk of physical and psychological harm caused by both drugs, as well as the risk of overdose.

Because of its high potential for abuse, methamphetamine is classed as a Schedule II drug under the Controlled Substances Act.

Can methamphetamine be used in medicine?

Desoxyn® is the only legal methamphetamine product available through a prescription, that cannot be refilled.

The drug is marketed in 5, 10 and 15-milligram tablets and has limited use in the treatment of attention deficit hyperactivity disorder (ADHD) and obesity.

How long does it take for methamphetamine to show up in a drug test?

Even after the ‘high’ has worn off, and long after the drug was first consumed, methamphetamine use can be detected by a drug test, depending on the type of test you take.

The drug testing detection windows for methamphetamine are as follows:

  • Oral fluid (saliva) – up to 48 hours
  • Urine – up to 4 days
  • Hair – up to 12 months (depending on the length of hair available)
  • Nails – up to 12 months (up to 6 months for fingernails and up to 12 months for toenails)

Oral fluid and urine drug testing are known as ‘narrow-window’ forms of testing and can be used to detect drug use from 30 minutes after consumption, up to a few days.

This can vary depending on the type of substance and how much was used.

The rate at which hair and nails grow means that both hair drug testing and nail drug testing can provide a ‘wide-window’ of detection for drugs and their metabolites (up to 12 months).
