Methamphetamine, more commonly known as meth or crystal meth, is a powerful synthetic stimulant drug that impacts the central nervous system. Meth works by releasing a flood of dopamine, a neurotransmitter related to reward and pleasure, which produces an intense rush followed quickly by a crash.[1] Because the high from meth wears off quickly, people tend to use it frequently in a short period of time, which greatly increases their risk of overdose and other adverse health effects.
Meth is classified as a Schedule II controlled substance because of its high likelihood for abuse, but some legal prescription forms do exist.[2] The crystal form of meth, which is most often used recreationally, is considerably more potent than prescription forms and carries health risks every time it is used.
Over the past several years, the number of people who use methamphetamine and die as a result of a meth overdose has increased dramatically. This is largely due to the increased presence of fentanyl, a synthetic opioid that is many times more potent than heroin, in the illegal drug supply.[3] Many people who use meth do not know their supply has been contaminated with fentanyl, adding another risk to an already significantly dangerous substance.
Yes, you can overdose on methamphetamine. A meth overdose occurs when the body takes in more methamphetamine than it can safely process, creating toxic effects that can result in permanent damage, including organ failure or death. Unlike an opioid overdose, where the primary danger is respiratory depression, a meth overdose primarily affects the cardiovascular and neurological systems.[4]
Because meth overdose creates a state of extreme overstimulation in the body, heart rate increases significantly, blood pressure rises, and body temperature can reach potentially lethal levels. All of these symptoms can cause a heart attack, stroke, or permanent organ failure even in otherwise healthy people.[5] An overdose can occur after a person’s very first use or after years of using. There is no safe amount of methamphetamine, and people sometimes have a false sense of security about their tolerance from having used it for a long time.
Recognizing the signs of a meth overdose can be the difference between life and death. The signs may differ for each person depending on the amount used, the other drugs involved, and the person’s general health. Common signs of meth overdose include:
Psychotic symptoms, including hallucinations, delusions, and disorganized thoughts or speech, may also occur during a meth overdose or during heavy use. When someone is having a psychotic episode while under the influence of meth, they may appear paranoid, agitated, or completely out of touch with reality. This can make it more difficult for others to recognize that a medical emergency is taking place.
If any of these signs or symptoms are present after using meth, treat the situation as a medical emergency.
In the case that you do encounter a meth overdose, taking the following steps can save a life:
Once emergency responders arrive, they will determine the best course of treatment, which may include medications to control heart rate and blood pressure, cooling measures for elevated body temperature, and supportive care in the emergency room.
One of the most dangerous public health trends in recent years is the contamination of the illicit meth supply with fentanyl.[6] Fentanyl is tasteless and odorless and only requires a very small amount to cause an overdose, so most people using meth will not know they are also taking fentanyl. The combination of a stimulant like meth and a potent opioid like fentanyl can produce unpredictable and potentially fatal effects.
If there is any indication that fentanyl may be involved in a meth overdose, naloxone should be administered as quickly as possible. Naloxone is available over the counter at most pharmacies and is carried by the majority of emergency responders.
Methamphetamine addiction, formally classified as a stimulant use disorder, is defined by the compulsion of the user to obtain meth regardless of the consequences. The effects of meth on the brain’s natural reward system make it very difficult to stop using meth without professional assistance.
There is currently no FDA-approved medication specifically for meth addiction, but effective treatment options do exist.
At Ikon Recovery, we offer a full continuum of care for anyone struggling with meth addiction, including partial care programs, intensive outpatient (IOP) services, and ongoing support designed to set each of our clients up for long-term success. If you or someone you care about needs help, reaching out is the first and most important step.
Yes. A meth overdose can result in death. Most commonly reported causes of death during a meth overdose include heart attack, stroke, and organ failure due to significantly increased body temperature. The higher the dosage of meth and the number of other drugs consumed, particularly opioids like fentanyl, the higher the risk of death.
Someone who overdoses on meth may experience severe chest discomfort, heightened anxiety, increased heart rate, and a feeling of panic. They may also experience difficulty breathing, confusion, or seizures. In some cases, the person will become unconscious or unresponsive.
There is no known safe amount of illicitly manufactured methamphetamine. The amount that causes an overdose will widely vary from person to person due to multiple factors, including weight, tolerance levels, overall health, and the presence of other drugs. Due to the highly variable potency of illicitly manufactured methamphetamine, further compounded by the potential unknown addition of fentanyl, the chances of experiencing a meth overdose are significant with any amount.
Naloxone does not reverse the stimulant effects of methamphetamine overdose. However, if fentanyl or another opioid was also involved, which is an increasing concern with illicit drugs, naloxone can be life-saving and should be administered. Always call 911 regardless of whether naloxone is available or has been administered.
Behavioral therapies like contingency management and CBT have been shown to be the most effective way to treat meth addiction. Most people receiving treatment will first go through detox, then continue with inpatient, partial care, or outpatient programs, depending on their care needs. At Ikon Recovery, we provide the resources necessary to help people recovering from addiction achieve success at each phase of their recovery journey.
