There's no denying that substance abuse is a serious issue that can have a monumental impact on several spheres of a person's life - not only in terms of health, although that's a big one, but also in regards to their relationships, both personal and professional. 

That's one of the main reasons why recognizing the signs that you or your loved one have a problem is a critical step in providing timely intervention, support, or getting them admitted into a meth rehab treatment center so they can start getting the help they need.

Unfortunately, it might be hard to notice an issue, as many people abusing substances tend to go to great lengths to hide that fact. Still, there are some symptoms that are tell-tale signs of drug abuse.

Those symptoms will vary depending on the substance that is being abused, as there are certain drugs that have a bigger impact on someone's physical appearance rather than their behavior, and vice-versa.

In this article, we will talk focus on methamphetamine abuse and what are the most common signs and symptoms that a person suffering from meth use disorder might show.

What Is Meth

Methamphetamine (also known as meth) is a highly addictive stimulant drug that affects the central nervous system. Methamphetamine is a white, odorless, bitter-tasting crystalline powder that can be snorted, smoked, injected, or taken orally. It is a powerful drug that increases the levels of dopamine in the brain, leading to feelings of euphoria, energy, and increased alertness.

Methamphetamine is a Schedule II stimulant under the Controlled Substances Act, meaning it has a high potential for abuse and dependence. It is illegal to use, possess, distribute or manufacture methamphetamines without a prescription from a licensed medical professional. Medical metamphetamine, which is typically taken in lower doses than street meth can be used to treat narcolepsy, as well as ADHD.

The drug's ability to induce euphoria, increase energy, and reduce appetite makes it appealing to users, but these short-lived benefits mask a host of detrimental effects on physical, mental, and emotional health.

What Are Signs of Meth Use

So, how to tell if someone is abusing meth? Below, you will find some of the most common symptoms of meth use.

Increased Physical Activity

Meth use can cause users to become more active than usual, including excessive talking and fidgeting. When meth is ingested, it is rapidly absorbed into the bloodstream and crosses the blood-brain barrier, where it acts on the central nervous system. 

The drug stimulates the release of dopamine and norepinephrine from neurons in the brain, leading to increased levels of these chemicals in the synapses (the small gaps between neurons), which, in turn, increases their levels, leading to increased feelings of alertness, energy, and euphoria.

Loss of Appetite

Meth use can cause a loss of appetite, which can lead to rapid weight loss. The exact mechanisms by which meth causes a loss of appetite are not fully understood, but there are several theories.

One theory is that meth affects the levels of certain neurotransmitters in the brain, such as dopamine and serotonin, which can lead to changes in appetite and food cravings. Dopamine, in particular, is known to play a role in regulating appetite, and meth increases its levels in the brain.

Another theory is that meth affects the release of hormones that regulate appetite, such as leptin and ghrelin. Leptin is a hormone that signals to the brain when the body has had enough to eat, while ghrelin is a hormone that stimulates appetite. Meth use can disrupt the normal balance of these hormones, leading to a loss of appetite.


Methamphetamine (meth) can affect the areas of the brain that regulate sleep and wakefulness, resulting in insomnia, which is a sleep disorder characterized by difficulty falling or staying asleep. It's important to note that prolonged meth use can lead to long-term sleep problems, even after you stop using it.

There are several ways in which meth use can cause insomnia:
Increased alertness
Meth stimulates the release of certain neurotransmitters, such as dopamine and norepinephrine, which can increase alertness and make it difficult to fall asleep.

Disrupted sleep patterns
Meth can interfere with the natural sleep cycle, leading to changes in sleep patterns, such as waking up frequently during the night or sleeping for shorter periods of time.

Anxiety and paranoia
Methamphetamine use can cause feelings of anxiety and paranoia, which can make it difficult to relax and fall asleep.

Physical symptoms
Meth use can cause physical symptoms such as tremors, muscle aches, and sweating, which can affect one's ability to fall or stay asleep.

Skin Sores

Methamphetamine (meth) can cause skin sores. Some of the reasons why that is the case include:
Skin picking
Meth can cause users to feel as if there are bugs crawling on or under their skin, a sensation known as "formication." In response to this feeling, some users may begin to pick or scratch at their skin, which can cause open sores and infections.

Reduced immune function
Methamphetamine use can suppress the immune system, making it more difficult for the body to fight off infections. This can make users more vulnerable to skin infections and sores.

Poor hygiene
Using meth can cause users to neglect their personal hygiene, which can increase the risk of infections and sores.

Chemicals in meth
Some of the chemicals used to make meth can be highly caustic and can cause chemical burns on the skin. In addition, meth users may be exposed to other chemicals and contaminants that can cause skin irritation and sores.

Compromised blood flow
Meth use can cause vasoconstriction, or narrowing of the blood vessels, which can reduce blood flow to the skin and increase the risk of tissue damage and sores.

Dental Problems

These dental problems are often referred to as "meth mouth" and can include a range of issues, including tooth decay, gum disease, and tooth loss.

There are several reasons as to why this is happening to those suffering from this particular substance use disorder, including:

Xerostomia (dry mouth)
Meth use can cause dry mouth, a condition in which the mouth produces less saliva than normal. Saliva plays an important role in neutralizing acids in the mouth and protecting the teeth from decay. Without enough saliva, the teeth are more vulnerable to decay.

Bruxism (teeth grinding)
Meth use can cause bruxism, or teeth grinding. Over time, this can cause tooth wear, chipping, and cracking.

Poor nutrition
Meth use can lead to poor nutrition, which can weaken the immune system and make the teeth more vulnerable to decay and infection.
Neglecting oral hygiene
Meth use can cause users to neglect their personal hygiene, including oral hygiene. Poor oral hygiene can contribute to tooth decay, gum disease, and other dental problems.

Chemicals in meth
Some of the chemicals used to make meth can be highly corrosive and can cause damage to the teeth and gums.

Other Meth Usage Symptoms

Dilated pupils 
Meth use can cause the pupils to dilate, leading to a glassy-eyed appearance.

Rapid heartbeat
Meth use can cause the heart rate to increase, leading to a pounding or irregular heartbeat.

Meth use can cause users to become agitated, irritable, and paranoid.

Meth use can cause users to experience hallucinations, including hearing voices or seeing things that are not there. Meth use can disrupt communication between different regions of the brain, leading to abnormal sensory processing and the perception of things that are not actually present.

Meth Addiction - Signs, Symptoms

Recognizing someone who is addicted to methamphetamine (meth) can be challenging, as individuals who use meth may try to hide their drug use or may not exhibit all of the typical signs and symptoms, especially since those can vary depending on the individual and the severity of their addiction.

Keep in mind that the presence of one or a few signs may not conclusively indicate meth addiction, but a combination of signs may warrant further investigation.

There are some common physical and behavioral signs that may indicate meth addiction, including:
Changes in physical appearance
Individuals who are addicted to meth may experience rapid weight loss, skin sores or rashes, dental problems (such as tooth decay or "meth mouth"), and a general decline in physical appearance.

Behavioral symptoms
Meth addiction can cause changes in behavior, including mood swings, agitation, irritability, and violent outbursts. Individuals may also become secretive, withdraw from social activities, and experience changes in their sleeping patterns.

Mental health symptoms
While meth addiction doesn't necessarily lead to the development of a new mental illness or mental health disorders, it can worsen the already present conditions.

Increased drug use
Individuals dealing with methamphetamine addiction may increase their drug use over time, and may experience withdrawal symptoms when attempting to stop using meth.

Financial problems
Meth abuse can be expensive, and individuals may experience financial problems due to their drug use, such as losing their job, borrowing money, or selling possessions to fund their addiction.

Legal problems
Meth addiction can lead to legal problems, such as arrest or incarceration, due to drug-related offenses.

The Bottom Line

Meth abuse can be life-threatening. After all, there's a reason why houses and apartments that have been used as meth labs tend to be inhospitable - this is mainly due to the toxic chemicals being released when cooking meth. Unfortunately, many of the methamphetamine types sold on the streets contain toxic ingredients that can be dangerous to your health.
