Many people have heard about the dangers of methamphetamine, often known by its street name: Crystal Meth. It is one of the most addictive and destructive recreational drugs on the planet, and yet few know how to identify the symptoms of meth addiction. While there are many negative behaviors associated with meth abuse, such as lying, stealing, and social isolation, there are also many physical and psychological symptoms. Let’s take a look at some of the most common symptoms to help you determine if a friend, coworker, or family member may suffer from meth addiction.

Rapid Weight Loss

Though weight loss can be a perfectly natural side effect of stress, diet, or something else entirely, rapid weight loss is often a sign of regular meth abuse. Meth turns off the body’s natural hunger response, which can cause the body to be starved of protein and important nutrients. This, in turn, can lead to extreme muscle degradation and general loss of body mass over a short period of time.

Tooth Loss or Decay

One of the most common and readily identifiable symptoms of meth addiction is tooth loss or decay, often referred to as “Meth Mouth.” If a person generally has healthy oral hygiene, but quickly develops tooth discoloration, decay, or gum disease, this could be a sign that meth is involved.

Agitation and Muscle Twitches

Crystal meth can cause users to feel extremely energetic. Their speech might be rapid and incoherent, while their movements will be accordingly strange. Twitchiness is very common among regular users. This may not be noticeable from a distance, but upon closer inspection, you will see rapid eye movements, muscle twitches, and exaggerated mannerisms.

Tweaking and General Paranoia

“Tweaking” is a term that refers to a specific stage of meth use. Once the initial high begins to wear off, meth addicts frequently become more aggressive, frustrated, and desperate to get high again. This stage, as well as meth use in general, is often associated with extreme paranoia. Users may feel that they are being watched or are under threat of violence, causing them to behave more erratically. Other common symptoms include insomnia that can last for days, and picking or scratching of the skin.

By themselves, these symptoms could be the result of unrelated issues, however together these build a strong case for meth addiction.
