Known as “glass,” “ice,” or “crystal meth,” methamphetamine is a popular party drug that’s highly addictive. Though meth has been around for decades – and even has some pharmaceutical uses – it ballooned in popularity during the 1990s.
Meth use comes with an intense euphoria that hits rapidly and subsides, leading people to use more to capture that feeling again. With repeated use, they develop a tolerance and, later, an addiction.
Methamphetamine – otherwise known as meth – is a highly addictive stimulant drug that is used as a recreational drug.[1] Though rare, meth may be used as a second-line treatment for attention deficit hyperactivity disorder (ADHD) and obesity.
Crystal methamphetamine is a common form of the drug that looks like glass fragments or shiny white rocks. Chemically, methamphetamine is similar to amphetamine. It may be consumed by smoking, swallowing it in pill form, inhaling it, or injecting it into the vein.
The euphoria from meth comes on quickly and fades just as fast, so people who use it tend to fall into a binge and crash pattern and take repeated doses.
Because meth carries a high potential for misuse and serious harm, it’s classified by the United States Drug Enforcement Administration (DEA) as a Schedule II substance. Though pharmaceutical meth is still produced, the street supply of meth is illicitly manufactured.
Typically, meth is made from over-the-counter cold medicines that contain pseudoephedrine or ephedrine. These components are then cooked with other chemicals such as phosphorus, acetone, or freon. Once these chemicals have been cooked, water will be added and then a solvent such as acetone will be heated to extract the meth from the concoction.
Meth contains dangerous chemicals that can be hazardous and poisonous to your body. Some of these chemicals that are used to produce meth include:[2]
Typically meth will appear to have an off-white, translucent, or white color to it. When other substances or drugs are added, it will naturally change colors. Some “cooks” of meth even started adding blue dye into their product to resemble the blue meth used in the hit TV show Breaking Bad.
Methamphetamine comes in various forms, so the look of it will differ based on the form that is purchased. The different forms of meth can affect the way they are taken.
One of the most common forms of meth is crystal meth. Crystal meth will have the appearance of shiny glass fragments or look like rock salt. This form of meth is made by dissolving meth powder into a solvent such as acetone or denatured alcohol. After the alcohol evaporates, it will leave behind the crystals. These crystals can be white, blue, or translucent and will be chunky.
Another of the most common and popular forms of meth is powdered meth. This form of meth can resemble cocaine or chalk dust. The color of powdered meth will highly depend on what substances and materials were used when making it. It is typically an off-white, light brown, or white color but may come in a variety of colors like green, red, blue, yellow, or pink.
While liquid meth is not sold on the street, it has become a popular way to transport and smuggle the drug. The meth will be dissolved in water and then trafficked in liquid form. Its appearance is a brown or dark yellow, syrupy kind of liquid. Later the liquid will be converted into crystal meth or powdered meth.
As you have already learned, meth can be prescribed for certain conditions such as ADHD or to manage obesity. When meth is obtained with a prescription from a healthcare provider, it will usually go under the brand name Desoxyn (methamphetamine hydrochloride). Oftentimes this prescription drug will be sold illicitly and used to get high. They are often sold as small green or reddish-orange colored pills or tablets.
Meth works by releasing the neurotransmitters serotonin, dopamine, and norepinephrine into the central nervous system (CNS) and peripheral nerve endings.[3] The release of these neurotransmitters allows the euphoric feeling of meth to be felt. When meth enters the brain and blood stream a variety of effects both physical and mental will take place.
Meth has a very distinctive taste. It is often said that it resembles the taste of rotten eggs. This can cause someone to not want to ingest meth and will find other means of taking the drug. The taste of meth is best described as a bitter, chemical-like taste in the mouth that is similar to burnt plastic, ammonia, or rotten eggs.
The smell that meth produces when it is being cooked depends heavily on what kinds of materials are being used. Pure meth will not have an odor but meth that is produced with toxic chemicals will have a pungent smell. The strong smell of meth may resemble cat urine, burnt plastic, ammonia, fertilizer, vinegar, nail polish remover, or rotten eggs.
While meth is highly addictive, using it doesn’t automatically cause an addiction. Common signs of meth use, such as nervous scratching, irritability, and fatigue, don’t necessarily fit the criteria for a substance use disorder.
True meth addiction includes several obvious signs and symptoms, particularly with someone’s appearance. Some of these signs include:
To be classified as an addiction, or a stimulant use disorder, someone has to use meth compulsively despite the negative effects on their life – and they must not be able to stop. According to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), a stimulant use disorder includes the following criteria:[4]
Methamphetamine is an addictive substance. It’s a potent stimulant with a high potential for addiction that can significantly alter the brain. Dopamine, a neurotransmitter that aids in regulating pleasure and motivation, is released in large amounts into the brain when users use meth. This burst of dopamine, or “rush, ” brings a tremendous surge of pleasure.”
However, once the effects of the drug start to wear off, users may encounter several unpleasant symptoms like irritation, paranoia, and anxiety. Because of these negative effects, some individuals may turn to meth again to feel better or regain the initial high.
When someone uses meth for a long period of time, they may develop dependence on the drug. This means that the body and mind are so accustomed to having meth in the system that they have negative reactions to it no longer being there.
Unlike heroin or some other drugs, meth withdrawal isn’t often life-threatening, but it can be extremely uncomfortable and difficult. The symptoms typically begin within a few days of stopping or cutting back on meth. Some psychological symptoms may take weeks to subside.
Some common meth withdrawal symptoms include:
Medical detoxification (detox) can help with the discomfort of meth withdrawal symptoms while the drug makes its way out of the system. There are no medications that are approved for stimulant withdrawal, but medications can treat symptoms like depression, anxiety, and insomnia.
With chronic use, meth can cause devastating physical and psychological effects, such as:[5]
Crystal meth has a big impact on the body and brain. As a central nervous system stimulant, meth stimulates the release of the neurotransmitter dopamine. However, meth can be more dangerous because a larger percentage of the drug remains unchanged in the body and stays present in the brain longer.[6]
Meth is toxic to the nerve terminals in the brain and can damage the synapses where dopamine is released, affecting the mood and leading to dependence. Chronic, long-term meth use can alter brain chemistry, making it more difficult to experience pleasure outside of the pleasure that comes from the drug.
Taking too much meth, or combining it with other substances, can increase the risk of a fatal overdose. Meth may be combined with other potent illicit substances, such as fentanyl, that can make it even more dangerous. An overdose of meth, with or without an additional substance, can cause potentially fatal effects like a heart attack or stroke.[7] Some additional signs of overdose include:
Meth addiction treatment can vary by the individual’s needs. Generally, meth addiction treatment involves several types of therapeutic techniques that work together to address the physical and mental effects of addiction.
Detox is often the first step for meth addiction. This allows the body to rid itself of the drug while keeping the person calm and comfortable, limiting the risk of relapse to make the discomfort stop. Though meth withdrawal isn’t often life-threatening, medical staff is available to limit the risks of complications.
Inpatient or residential treatment is a typical step after detox. People stay in a facility around the clock to receive intensive care, including individual and group therapy, behavioral therapies, and other modalities. Once inpatient treatment is complete, outpatient programs provide ongoing therapy without the need to stay in a facility day and night. This helps people transition from constant care to more independent environments while attending therapy sessions.
For some people, transitioning from outpatient treatment to aftercare helps with coping skills to avoid relapse, adapt to stress, and build support systems. Whatever form it takes, effective meth addiction treatment addresses the addiction itself and the underlying factors that contribute to it.
Most health insurance companies offer coverage that includes the expense of substance use disorder, including meth and other narcotics. Meth addiction treatment is frequently regarded as a type of healthcare.
Amphetamines like meth can do serious damage to the body. The nature of these drugs is to speed up the brain’s processing. Once consumed, amphetamines increase breathing and heart rate while decreasing hunger. With higher doses, the person may experience a rapid rise in body temperature, sweating, nausea, headache, dizziness, blurred vision, loss of coordination, and possible collapse.
Meth can be smoked, injected, taken orally in pill form, or inhaled. It comes in powder, pill, and crystal form.
Meth differs across producers, but it generally looks like white powder. Crystal meth looks like shards of glass, which is why it has slang names like “ice” and “glass.” It may be clear, white, gray, or bluish-white.
Meth overdose is a serious risk with meth consumption. In addition to the risks with the meth itself, it may be laced with other drugs like fentanyl that can compound the potency and, by extension, the risks. Naloxone, an opioid antagonist, is not effective against stimulant overdoses such as those caused by meth. However, it should be administered in cases where opioid co-ingestion is suspected or confirmed, as it can reverse the effects of opioid overdose.
Chronic meth use leads to extreme tooth decay, which is known as “meth mouth.” Several factors can contribute to tooth decay, both directly and indirectly:
The tooth decay from meth use may have symptoms like cavities, stained teeth, swollen gums, loose or missing teeth, and damaged teeth. In severe cases, the person may struggle to speak or chew. Though the damage from meth mouth can be severe and irreversible, there are treatment options to restore the look and function of the teeth. Dentures or implants can replace missing teeth, the teeth can be deep cleaned to mitigate gum disease, and cavities can be repaired. Early treatment of meth-related tooth decay is key to better outcomes.
Crystal meth is a purified form of meth, typically in the form of crystals or rocks. Generally, meth is a broad category that may include the powder, pill, or crystal form, whereas crystal meth refers exclusively to the rock crystal form.
Meth use and addiction comes with serious risks, including long-term health or psychological conditions or possible death. If you or a loved one are struggling with a meth addiction or stimulant use disorder, it’s vital that you seek help to minimize the risks and get on a healthier path.
