Methamphetamine and Crystal Meth Addiction: Signs and Side Effects of Meth Abuse

Methamphetamine is a Schedule II controlled substance that works as a stimulant for the central nervous system. While Desoxyn methamphetamine is sometimes prescribed on a limited basis to treat attention-deficit hyperactivity disorder (ADHD), most methamphetamine use involves illicit forms, such as crystal meth.

Methamphetamine and crystal meth have several street names, and many are based on the shape and appearance of crystal meth, such as crystal, ice, glass and shard. Other common names for tina, crank and speed. Meth abuse can include smoking, snorting, ingesting or injecting the substance. Using methamphetamine or crystal meth intravenously can raise the risk of addiction and overdose.

In this article, we focus on the signs of methamphetamine addiction and the negative effects it can have on your physical and mental health. We also explain the difference between stimulant addiction and abuse and what factors can increase the risk of developing a crystal meth addiction.

Methamphetamine has a high risk of addiction, officially called substance use disorder or stimulant use disorder, because of the way it affects the brain and the rest of the central nervous system. It slows the reuptake of dopamine and other neurotransmitters, leading to higher dopamine levels in the brain. This leads to an intense but fairly short-term high followed by a crash, sometimes referred to as the stimulant reinforcement cycle.

The way meth and dopamine affect each other can lead to the meth binge cycle. Using meth boosts dopamine, but as the levels drop again, the person can experience withdrawal symptoms and side effects, and meth cravings begin. Stress, strong emotions and even certain people or environments can also start to trigger cravings.

Over time, the person builds up a meth tolerance, meaning they need to use more of the substance to get the same effect. This is when meth abuse, officially referred to now as “misuse,” starts to turn into addiction.

Understanding the difference between meth abuse vs. addiction can help you determine what’s going on in your or a loved one’s life and where to go from here. Methamphetamine abuse or misuse is any nonmedical use of methamphetamine. This can include crystal meth abuse or using higher-than-prescribed doses of Desoxyn methamphetamine.

Problem stimulant use starts to become an addiction where there’s compulsive meth use, which includes feeling out of control around methamphetamine, experiencing strong cravings or continuing to use even when there are negative consequences to your health, finances or relationships.

Meth use disorder may not always be obvious. Some people start with occasional use, such as to stay up and study for a test or to lose weight, and then end up in the meth binge cycle. This can lead to feeling like you need meth to be able to function on a daily basis.

Over time, your body can start to become dependent on methamphetamine. This happens because the body becomes accustomed to the elevated levels of dopamine and other neurotransmitters in the brain and establishes a new normal. When someone tries to stop using meth, the body goes through withdrawal.

Physical withdrawal symptoms are unpleasant, and the person may use again to feel better, reinforcing the cycle. Psychological dependence on meth is also possible if someone starts to rely on meth for motivation, energy or confidence.

Meth dependence isn’t the same thing as addiction, but it’s a warning sign that misuse is happening and may be escalating.

Because methamphetamine has such a strong effect on the brain, a person’s misuse can quickly develop into substance abuse. Common physical signs of meth abuse or addiction include reduced appetite and weight loss or difficulty sleeping. The person may also experience an increased heart rate, irregular heartbeat and excessive sweating.

Meth skin picking is a hallmark of the addiction. Using meth can make it feel like there are bugs under the skin or that something is crawling on the person, leading them to pick at their skin obsessively. Slow wound healing can lead to open sores and infection.

Crystal meth symptoms can also affect someone’s mental state. They may feel irritable or agitated or experience meth paranoia, which is the common term for the high levels of anxiety that can happen with long-term meth use.

Meth addiction warning signs may show up in how a person interacts with others or performs at work. Someone misusing meth may make riskier decisions, experience more relationship conflicts or continue to use even if it’s negatively affecting their life.

When the brain is used to having the increased dopamine from meth, stopping can lead to meth withdrawal symptoms, sometimes called the crystal meth crash. These include:

• Intense meth cravings
• Depression or anxiety
• Irritability and mood swings
• Brain fog and difficulty concentrating
• Increased appetite
• Extreme fatigue and increased need for sleep
• Vivid dreams or distressing nightmares
• Feeling restless

Stimulant withdrawal symptoms depend on how long you’ve been using the substance and in what doses. However, a common meth withdrawal timeline to get past the initial intense cravings and symptoms is about 2 weeks.

The immediate effects of meth abuse include a feeling of euphoria and increased energy or alertness. Physically, the person may have an increase in heart rate, blood pressure and temperature. Long-term meth effects include the risk of cardiovascular damage and meth psychosis due to its impact on the brain’s reward centers and chronic sleep disruption. Dental problems, referred to by some as “meth mouth,” and skin infections are also common.

The long-term effects of methamphetamine also include an increased risk of stroke, seizures and overdose, which can be fatal. Mixing meth and alcohol or other substances can increase the risk of adverse health effects and overdose.

Anyone can become addicted to methamphetamine, and having a substance use disorder doesn’t mean that you are a bad person or a failure. However, the presence of certain mental health, behavioral and environmental factors can increase your risk. Risk factors for meth addiction include:

• Having a previous history of anxiety, depression or chronic stress
• Experiencing trauma
• Feeling intense pressure related to school or work performance or weight loss
• Growing up in a household where people misused substances
• Misusing substances in the past
• Using multiple substances, such as mixing meth and alcohol
• Having friends who use meth or other substances

Diagnosing meth addiction starts with visiting a trained healthcare provider who has experience with stimulant use disorders. They’ll talk with you about your behaviors and symptoms to determine if you meet the meth use disorder criteria. This can include a meth addiction assessment to determine how much and how long you’ve been using methamphetamine and whether there are other factors, such as health problems or risky behaviors.

Stimulant use disorder diagnosis also commonly includes a mental health screening to determine if there are any other co-occurring conditions, such as depression or anxiety. You may also need to go over your sleep patterns and eating habits or have a heart test to determine whether you’re experiencing cardiovascular symptoms.

Once a clinician has determined that you have substance use disorder, they can talk to you about what that means for your health and what treatment options may be available.
