Effects of Meth on the Brain: Cognitive and Emotional Changes

Meth is a drug that is a public health concern. The National Institute of Drug Abuse reports that around 2.5 million people used meth in 2021. It is a drug that, when taken, can have a number of profound effects on the user, not just on their body but also on their mind. Long-term use of methamphetamine can lead to effects that can last long after someone stops using meth.

Meth, or methamphetamine, crystal, meth, speed, or crank, is a highly addictive and potent central nervous system stimulant. It’s classified as a Schedule II stimulant under the Controlled Substances Act, which means that it has a valid medical use but also has a high risk for addiction and misuse.

Understanding Methamphetamine Addiction

Methamphetamine addiction is a condition in which a person has no control over their use of the drug. When a person is addicted, methamphetamine use becomes their highest priority. They will think about meth constantly. They may even neglect other parts of their lives in favor of using meth.

Methamphetamine addiction can be caused by a number of factors. Genetics can be a major factor, as addictive personality traits and mental health disorders,  a major trigger for drug use, can run in families. Growing up in an environment where drug use was normalized can also make a person more susceptible to substance use disorder, as can having friends and family members who use drugs.

Effects of Meth on the Brain

Using meth can have several effects on the brain. Some of these effects can include:

Cognitive Impairment

Meth use can cause a person to suffer cognitive impairment. This can include having issues with attention span, memory, and impaired decision-making abilities.

Increased Alertness

As a stimulant, meth can immediately increase a user’s energy and wakefulness, making them feel more alert.

Psychological Issues

Long-term meth use can also lead to the development of mental health disorders such as depression, paranoia, and psychosis, a condition characterized by delusions, hallucinations, paranoia, not unlike schizophrenia. These issues can persist even after someone stops using meth.

Neurotoxicity

Meth can trigger an immediate rush of dopamine, which is a neurotransmitter associated with pleasure, reward, and motivation. This rush of dopamine creates the high that can compel users to use methamphetamine again and again.

However, using meth can damage dopamine and serotonin neurons in the brain. These neurotoxic effects can lead to many of the effects outlined above.

Increased Risk of Stroke

One of the effects of meth use is that, like other stimulant drugs, it can increase a person’s blood pressure. Over time, this can increase a user’s risk of suffering a stroke.

Signs of Meth Addiction

Many signs may indicate the use of meth. Many meth users can also neglect their hygiene, which can lead to a haggard appearance. Many people with a chronic meth habit may also change their social circles and begin to spend time in the company of other meth users.

Some people who use meth may also exhibit twitchy or jerky movements, and they may suffer from insomnia and go for days without sleeping, which can further affect the brain and body.

Long-Term Effects of Meth Addiction

One of the long-term effects of methamphetamine is weight loss, as meth affects a person’s appetite. This can lead to malnutrition. Chronic methamphetamine use can also result in skin sores for a variety of reasons, such as physical contact with meth, a weakened immune system, and tactile hallucinations leading to excessive scratching.

Another long-term effect of methamphetamine misuse is a series of dental and oral health problems known as ‘meth mouth.’ This is because meth can disrupt saliva production and can wear down the teeth’s enamel due to its corrosiveness. 

Meth can also potentially lead to a person becoming infected with HIV or hepatitis. It’s not uncommon for users to share needles. This practice facilitates the spread of infectious diseases.

Using meth can also lead to sexual dysfunction, including impotence in men and reproductive complications in women.

Regular meth use can also lead to tolerance, which can compel a person to use larger amounts of the drug to get the same high. Chronic meth use can lead to dependence, which can result in withdrawal symptoms if a person ever stops taking meth.

Short-Term Effects of Meth Addiction

The most prominent short-term effect of meth is the rush of euphoria or the high that someone gets. Some users can also experience hyperthermia or an increase in body temperature. Meth users can also experience dry mouth and grind their teeth, which can lead to the previously mentioned meth mouth. Their pupils may also dilate.

Behaviorally, being on meth can give someone a boost in confidence and make them more sociable. Conversely, the drug’s influence can also make them more aggressive or irritable.

Treatment for Meth Addiction

Meth addiction is a treatable condition. Numerous meth addiction treatment programs are designed to help a person overcome their drug use.

One major way to treat an addiction to meth is with inpatient rehab. While in a treatment center, a person will be in a controlled environment where they will receive intensive support for their drug habit. Other treatment options for meth addiction include detox, aftercare, and holistic treatments to enhance overall well-being and complement conventional therapies.
