Key Points
  • Meth sores are open wounds and scabs caused by excessive skin picking, poor hygiene, and toxic chemicals from methamphetamine use.
  • Long-term meth use leads to rapid aging, sagging skin, deep wrinkles, acne, and scarring due to dehydration, malnutrition, and reduced collagen production.
  • With proper medical care, improved hygiene, nutrition, and addiction treatment, some effects of meth sores and "meth face" can be reversed.

Methamphetamine (meth) is a highly addictive stimulant with devastating effects on both the mind and body. Among its many harmful consequences, meth sores are a common and visible sign of prolonged use. These painful, open wounds can develop anywhere on the body but are most commonly seen on the face, arms, and legs.

Meth sores not only indicate severe substance use but also increase the risk of infections and long-term skin damage. Let’s take a look at what causes these sores, how to treat them, and the importance of seeking help for meth addiction if you or someone you know is struggling.

What Are Meth Sores?

Meth sores are open wounds, ulcers, or scabs that appear on the skin due to chronic methamphetamine use. [1] These sores often result from excessive scratching, poor hygiene, and exposure to harmful toxins found in meth.

Acne on face because the disorders of sebaceous glands productions due to meth use.

People who use meth may experience severe itching and a crawling sensation under their skin (a condition known as formication), leading them to scratch and pick at their skin compulsively. Over time, this behavior causes widespread sores, infections, and permanent scarring.

Common Locations of Meth Sores

Meth sores can appear anywhere on the body, but the most frequently affected areas include:

  • Face
  • Arms
  • Legs
  • Neck
  • Lips and inside the mouth
  • Genital area

What Do Meth Sores Look Like?

Meth sores can take on different appearances depending on the severity of use and how often a person picks at their skin. While they may start as minor blemishes, they can quickly worsen due to repeated scratching, infections, and poor healing.

1. Red, Inflamed Patches

In the early stages, meth sores often appear as small, red, irritated patches on the skin. These may resemble pimples, bug bites, or rashes. The irritation is usually caused by excessive scratching due to the sensation of “meth mites” crawling under the skin.

2. Open Wounds and Scabs

As a person continues to scratch, these inflamed areas can break open, forming raw wounds and scabs. Because meth users frequently pick at their skin, these sores struggle to heal correctly, often reopening and worsening over time.

3. Deep Abscesses and Infections

Bacteria entering open wounds can lead to painful abscesses—large, swollen pockets of infection beneath the skin. These abscesses may be filled with pus and require medical treatment to prevent further complications, including cellulitis or systemic infections.

4. Crusted or Ulcerated Lesions

Over time, untreated meth sores can develop into crusted, ulcerated lesions that leave behind permanent scars and skin discoloration. These are most commonly seen on the face, arms, and legs, where picking occurs most frequently.

Because meth sores can quickly become infected, they often result in swelling, extreme pain, and pus formation. These wounds can worsen without proper care, leading to serious health risks that extend beyond the skin. Seeking treatment for meth addiction is the best way to stop the cycle of self-inflicted skin damage and allow the body to heal.

What Causes Meth Sores?

Meth sores develop due to a combination of physical, psychological, and behavioral effects caused by meth use. Some of the leading causes include:

5 Causes of Meth Sores - Last Resort Recovery Center

1. Skin Picking & Meth Mites

One of the hallmark effects of meth use is formication, the false sensation of insects crawling under the skin, often referred to as “meth mites.” 

This sensation is a type of dysesthesia, a neurological condition that causes abnormal and usually painful skin sensations, such as burning, tingling, or prickling. [2] Meth disrupts nerve function, making these sensations more intense and persistent. In response, individuals may scratch and pick at their skin excessively, leading to open wounds, infections, and long-term scarring. 

Since meth also weakens the body’s ability to heal, these sores often worsen over time, increasing the risk of severe skin damage and secondary infections.

2. Poor Hygiene & Skin Infections

Meth use often leads to neglect of personal hygiene, increasing the risk of bacterial infections. Open sores become entry points for bacteria like Staphylococcus aureus (staph infection), including MRSA, a drug-resistant form of staph that can lead to severe complications.

3. Toxins in Meth Sweating Through the Skin

Meth contains toxic chemicals that exit the body through sweat. These toxins can irritate the skin, clog pores, and contribute to the formation of sores, rashes, and acne.

4. Burns from Meth Pipes

Many meth users smoke the drug using a hot glass pipe, which can lead to burns on the lips, mouth, and fingers. These burns often become painful blisters and sores that take a long time to heal.

5. Malnutrition and Weakened Immune System

Meth suppresses appetite, leading to malnutrition and severe vitamin deficiencies. A lack of nutrients, especially vitamin C and zinc, weakens the immune system, making it harder for the body to heal wounds and fight infections.

What Is “Meth Face”?

Chronic methamphetamine use doesn’t just cause sores—it also leads to an overall deterioration of the skin, commonly referred to as “meth face.” This term describes the rapid aging, sagging skin, deep wrinkles, acne breakouts, and severe dryness that often develop in long-term meth users.

Several factors contribute to this dramatic change in appearance:

  • Extreme Dehydration – Meth suppresses thirst and increases body temperature, leading to severe dehydration. Over time, this causes the skin to lose elasticity, making it look aged and sunken.
  • Nutritional Deficiencies – Meth use often leads to malnutrition, depriving the body of essential vitamins and nutrients that support healthy skin.
  • Reduced Collagen Production – Meth constricts blood vessels, cutting off oxygen and nutrients to the skin. This speeds up collagen breakdown, leading to sagging skin and deep wrinkles.
  • Persistent Skin Picking – Repeated scratching and picking at the face can result in scarring, open wounds, and infections, contributing to the overall damaged appearance.

While some effects of meth face can be reversed with proper medical care, long-term meth use can cause lasting damage to the skin and body. The best way to prevent or improve these symptoms is to seek professional addiction treatment and allow the body time to heal.

The Dangers of Meth Sores and Associated Health Risks

While meth sores may seem like a superficial issue, they can lead to life-threatening health complications if left untreated. Some of the significant risks include:

4 Risks of Meth Sores - The Last Resort

1. Skin Infections & Abscesses

  • Open wounds can become infected with bacteria, leading to painful abscesses, cellulitis, and even sepsis.
  • Methicillin-resistant Staphylococcus aureus (MRSA) is prevalent among meth users and can cause hard-to-treat infections.

2. Permanent Scarring & Skin Damage

  • Repeated picking and scratching can cause deep scars, discoloration, and tissue damage.
  • Over time, the skin may thin, become rough, and lose elasticity, making it look prematurely aged.

3. “Meth Mouth” and Oral Sores

  • Meth use reduces saliva production, leading to dry mouth, severe tooth decay, gum disease, and oral infections. [3]
  • Smoking meth can cause burns inside the mouth, leading to ulcers and painful sores on the lips and tongue.

4. Increased Risk of Bloodborne Diseases

  • Injection meth users risk contracting HIV, hepatitis B, and hepatitis C due to needle sharing and open wounds.
  • Unsterile injection sites can also develop serious abscesses and vein damage.

Long-Term Effects of Meth Use on the Skin and Body

Meth doesn’t just cause temporary damage—it alters the body permanently. Some long-term effects of chronic meth use include:

  • Severe weight loss & muscle wasting
  • Premature aging & wrinkled skin
  • Extreme acne and persistent skin infections
  • Psychological issues like paranoia, hallucinations, and anxiety
  • Organ damage, particularly to the heart and kidneys

Many of these effects persist even after stopping meth, making early intervention and treatment crucial.
