Meth Street Names and Slang Terms

Methamphetamine or meth is a stimulant with powerful effects, and as is true with other illicit substances, there are a number of street and slang names used to refer to it. Regardless of what the meth street names are, it doesn’t change the risks of this substance and the fact that it requires professional treatment to overcome an addiction.

How Does Meth Work?

Methamphetamine or meth is a potent stimulator of the central nervous system. It’s classified as an amphetamine.

When someone uses amphetamine, it both increases the release and blocks the reuptake of neurotransmitters in the brain. This leads to a surge in their activity, so the person will experience high energy levels, euphoria and alertness. These effects make methamphetamine incredibly addictive and prone to abuse.

Short-term meth effects include:

• Intense feelings of well-being and pleasure are also described as euphoria.
• Feelings of being awake, energetic and focused.
• Reduced appetite can lead to significant weight loss.
• Higher heart rate and blood pressure because the drug stimulates the cardiovascular system.
• Dilated pupils.
• Higher body temperature leads to sweating and dehydration.
• Increased likelihood of risk-taking behavior because of inflated confidence and reduced inhibition.

With longer-term or chronic meth use, effects can include:

• Addiction and dependence.
• Neurological damage, including structural and functional brain changes, leads to memory loss, decreased motor skills and cognitive impairment.
• Psychiatric disorders include psychosis and paranoia.
• Dental problems often called “meth mouth” include tooth decay and loss and gum problems.
• Skin sores because of skin picking. This often happens because meth can create hallucinations like insects crawling under the skin. The sores can become infected.
• Chronic methamphetamine use can lead to heart arrhythmias and palpitations and a higher risk of heart attack and stroke.
• Respiratory issues like lung damage and chronic bronchitis.

Some of the signs and symptoms of meth use can depend on how a person is consuming it. The ways the drug can be used include:

• Orally: It can be swallowed in pill form, but the method is less common because it has a slower onset and less intense effects.
• Snorting: Powdered meth can be crushed into a powder and snorted through the nose, allowing it to be absorbed into the bloodstream rapidly.
• Smoking: When meth is in crystalline form, known as crystal meth or ice, it can be heated, vaporized and then inhaled through a glass tube or pipe. When a person smokes meth, it tends to produce an intense, rapid high because it’s quickly absorbed into the bloodstream and lungs.
• Injection: If methamphetamine is dissolved in water, it can be injected into the bloodstream with a syringe, producing an immediate, powerful high. This also creates the risk of infectious diseases and vein damage, as well as a greater likelihood of overdose.
