Speed, or methamphetamine, is a potent and addictive central nervous system stimulant. It is a white, odorless, bitter-tasting powder that easily dissolves in water or alcohol and is usually smoked, snorted, injected, or taken orally. While the effects of speed can include increased energy, alertness, and euphoria, the drug also carries serious health risks, including the potential for addiction, overdose, and long-term damage to the brain and cardiovascular system. Given these dangers, it is important to consider the potential impact of speed on muscle health in addition to its broader health consequences.

What You'll Learn

Speed is a central nervous system stimulant
Speed, or methamphetamine, is a central nervous system (CNS) stimulant. It is a potent and addictive stimulant that affects the way the brain works and how the body functions. CNS stimulants speed up messages between the brain and body, increasing energy, alertness, concentration, and heart rate, while reducing appetite and sleep.
Speed is a type of amphetamine, a class of drugs that are chemically related to each other. Amphetamines are stimulant drugs that speed up the workings of the brain. Some amphetamines are prescribed by doctors to treat conditions such as attention deficit hyperactivity disorder (ADHD) and narcolepsy. However, speed is an illegal form of amphetamine that is produced and sold illicitly.
The effects of speed are felt quickly if the drug is injected, smoked, snorted, or taken orally. It can make users feel happy and increase their confidence and energy levels. However, it can also cause unwanted effects, such as aggression, paranoia, anxiety, and hallucinations. High doses and frequent use of speed can lead to psychosis, which can be similar to schizophrenia.
Withdrawal from speed can be challenging and may result in symptoms such as nausea, extreme exhaustion, irritability, and depression. Long-term use of speed can lead to serious health problems, including changes to the brain, cardiovascular damage, malnutrition, memory loss, and severe dental problems. Speed is highly addictive, and misuse of the drug can lead to severe and undesirable side effects, including death.

Speed is highly addictive
Speed is a central nervous system stimulant that affects the way the brain works and how the body functions. It is a type of amphetamine that can be smoked, snorted, injected, or taken orally. Speed is highly addictive and can cause serious health issues, including damage to the brain and cardiovascular system.
The drug is known to produce a rush of energy, alertness, and euphoria, which can quickly lead to dependency. The fast-acting high can trigger a cycle of emotional and physical dependence, with users feeling they need the drug to stay productive, social, or functional. Over time, tolerance builds, leading to increased use and a higher risk of harm.
The intense sensation, or "rush", produced by speed is extremely pleasurable, and users may find themselves chasing this high by increasing their dosage and frequency of use. As the pleasurable effects of speed diminish, users may find themselves taking more and more of the drug to achieve the same effect, leading to addiction.
Speed addiction can have severe consequences on both physical and mental health. Physically, users may experience an elevated heart rate, high blood pressure, insomnia, and weight loss. Mentally, speed addiction can lead to mood swings, irritability, anxiety, paranoia, and depression. Coming down from speed can take up to four days, during which users may experience extreme exhaustion, irritability, and depression.
Withdrawal from speed can be challenging, with symptoms including nausea, extreme exhaustion, irritability, and depression. However, most withdrawal symptoms disappear after a month. Behavioural therapy, counselling, and peer support are recommended treatments for speed addiction.

Speed withdrawal symptoms
Speed, or methamphetamine, is a potent and addictive central nervous system stimulant. It is chemically related to amphetamine but has greater central nervous system side effects. Withdrawal symptoms from speed can be intense and challenging to manage. The initial phase of withdrawal, known as the "crash", usually occurs within 24-48 hours of the last use and can last 1-2 days. During this phase, individuals may experience an increased need for sleep, depression, increased appetite, and cravings. This is followed by a longer period of withdrawal that can last from 5 days to several weeks, with symptoms such as mood swings, irritability, aches and pains, trouble sleeping, and fatigue. Some individuals may also experience psychotic symptoms during this time, particularly if they were present during periods of use.
Withdrawal symptoms from speed can be difficult to manage, and seeking professional help is often necessary. Behavioural therapy and counselling are recommended as effective treatments for speed withdrawal. Support groups and peer support can also be beneficial. In some cases, medication may be prescribed to manage specific symptoms such as depression, irritability, and agitation. However, it is important to note that there are currently no medications specifically approved for the treatment of speed addiction.
The duration of withdrawal symptoms can vary, with most symptoms reducing after a week and disappearing after a month. However, in some cases, particularly with chronic use, symptoms can last much longer. Protracted or post-acute withdrawal symptoms (PAWS) can occur when withdrawal effects last longer than 2 weeks, and these can persist for up to a year or more. These symptoms can include continued mood changes, fatigue, and cognitive difficulties.
The health hazards and brain changes associated with chronic speed use appear to be at least partially reversible over time. Brain neuroimaging studies have shown recovery of dopamine transporter activity after approximately 2 years of abstinence. Motor skills and verbal memory tests have also shown some improvement, but not all changes may reverse. It is important to seek medical advice when planning to stop taking speed, as withdrawal can be challenging and may require professional support.

Speed causes psychosis and violent behaviour
Speed, or amphetamine, is a stimulant drug that speeds up the messages travelling between the brain and the body. It is a highly addictive substance that can lead to physical and mental health issues. The effects of speed are felt quickly if the drug is injected or smoked, and can last for several hours.
Amphetamine psychosis is a well-known effect of speed use. Psychosis is when a person loses the capacity to distinguish reality from their imagination. It is often accompanied by hallucinations and paranoia. High doses and frequent use of speed can cause psychosis, with symptoms similar to those of schizophrenia. These symptoms include hallucinations and aggressive behaviour. In some cases, psychotic episodes may recur for months or years after speed abuse has stopped.
Speed can also cause violent behaviour. The drug decreases inhibitions and can lead to mood swings, with users reporting feelings of anger and irritability. Violent behaviour is a known symptom of a speed overdose, which can occur when someone takes more speed than their body can handle. Overdose symptoms include extreme restlessness, a dangerously fast heart rate, high body temperature, and seizures.
Long-term use of speed can lead to many challenges, including mental health disorders such as depression, anxiety, and schizophrenia. It can also cause physical health issues like fatigue, aches, and sores. Speed is a dangerous substance that can lead to addiction and serious health problems, including heart disease and malnutrition.

Speed increases risk of heart attack and stroke
Speed, or methamphetamine, is a potent and addictive central nervous system stimulant. It is chemically related to amphetamine but has greater central nervous system side effects. It is classified as a Schedule II stimulant by the U.S. Drug Enforcement Agency (DEA), indicating its high potential for abuse and restricted availability through prescription.
The use of speed can lead to a range of adverse health effects, including an increased risk of heart attack and stroke. Regular consumption of speed can cause high blood pressure, heart disease, and damage to blood vessels. As a result, individuals who frequently use speed are at a heightened risk of experiencing a heart attack or stroke, even at a young age. The risk is further exacerbated when speed is combined with other stimulants, such as cocaine or MDMA, as this places additional stress on the heart and can lead to sudden, life-threatening complications.
Additionally, the body's confusion in distinguishing the effects of stimulants and depressants when speed is mixed with central nervous system depressants like alcohol, marijuana, or sleeping pills can also severely strain the heart and nervous system. This confusion may lead individuals to misjudge their level of intoxication, potentially resulting in alcohol poisoning.
The overdose of speed can be fatal and may manifest as extreme restlessness, a dangerously fast heart rate, high body temperature, and seizures. In severe cases, an overdose can progress to a heart attack, stroke, or organ failure. Therefore, it is crucial to seek immediate medical attention in the event of a suspected overdose.
The long-term use of speed can also lead to serious health issues, including changes to the brain, cardiovascular damage, malnutrition, anxiety, and paranoia. These problems can further increase the risk of heart attack and stroke over time.
