Over 1mill people age 12 and older were addicted to Meth in 2019 (NIDA), and that number continues to grow which displays why substance abuse help is so necessary. Meth, also known as methamphetamine, is classified as a Schedule II drug in the United States. It is a highly addictive drug that serves as a central nervous system stimulant. While there are medical forms of amphetamine that exist for particular conditions, meth is still widely used as an illegal substance. 

In 2018, it was reported that over 1.9 million Americans over the age of 12 had used meth during the year. In many areas, it is easy to access and often comes mixed with other substances that lead to needing further substance abuse help. Meth has multiple names it is known by including crank, crystal, glass, ice, rock candy, and speed. 

Meth is known for giving a “rush” or “flash” effect that is often equated to the feeling of euphoria when injected. It is consumed by snorting it through the nose, ingesting it orally, or injecting it. In some cases, the “rush” feeling can give a longer-lasting high that is present for nearly half a day. 

Meth stays longer in the system because the body does not immediately metabolize it like other drugs. This means the stimulant effects of meth are present in the body longer, causing a longer and more addictive high. Meth use is closely linked to severe side effects that impact memory, brain function, and behavior. 

If meth is not intervened through professional help, it can lead to long-term issues and severe consequences. 

The Half-Life of Meth

Meth is known for having a half-life that lasts up to 12 hours. That means 50% of the meth you consumed will leave your body, but the other half can linger in your system for up to three days after use. 

If meth is snorted or smoked, it will take a shorter amount of time for meth to leave the body. If it is injected, it will linger longer within your system. Recognizing the half-life of meth is important when detecting it, as it will affect side effects in the body far longer than just taking an initial dose. If you have been taking meth for a longer period of time, your body may have adapted to seeing it in your bloodstream, which means it will take a longer time to break down. 

The Effects of Meth Use

Meth use effects can last anywhere from four to twenty-four hours, depending on the method and amount of use. However, withdrawal symptoms are incredibly uncomfortable compared to other substances. 

Cravings are severe and often cause individuals to use even more heavily without proper addiction help. As a response, meth has the ability to create intense behavior that can turn to violent responses, including putting a person in potential danger of harming themselves, or others. 

Withdrawal Symptoms Include:

  • Increased appetite
  • Fatigue
  • Irritability
  • Aggressiveness
  • Anxiety

Type Of Use

Other Substance Use

Dangers include:

  • Intense cravings
  • Mental confusion
  • Paranoia
