How Amphetamines Affect Your Body and Mind
Amphetamines are powerful stimulant drugs that can give you a boost of energy and focus. They work by affecting the brain’s chemistry, making you feel more alert and awake by increasing certain neurotransmitters, like dopamine and norepinephrine.
While doctors may prescribe amphetamines to help with conditions like ADHD or narcolepsy, using them for non-medical reasons can lead to serious health risks. Knowing how these drugs affect your body is important in understanding both their potential benefits and the dangers they pose when misused.
Key Takeaways
Amphetamines boost dopamine, norepinephrine, and serotonin, increasing energy, focus, and mood. While prescribed for ADHD, misuse can cause serious health risks. Treatment addresses both physical and psychological aspects, helping manage cravings and underlying issues for healthier patterns.
- Amphetamines work by increasing levels of neurotransmitters like dopamine and norepinephrine, which leads to heightened alertness, focus, and energy. However, using them outside of a medical setting can lead to serious health risks.
- While amphetamines can be prescribed for conditions like ADHD and narcolepsy, they are also commonly misused recreationally. Different types of amphetamines, such as Adderall and methamphetamine, have varying effects on the body and mind.
- Short-term effects include increased energy, euphoria, and improved focus, while long-term use can lead to tolerance, addiction, cardiovascular issues, and mental health problems.

A Closer Look at Amphetamines
Amphetamines are a class of central nervous system stimulant drugs that affect neurotransmitters in the brain, particularly dopamine and norepinephrine. They stimulate the central nervous system, increasing alertness, improving focus, and elevating mood.
Amphetamines are commonly prescribed for medical conditions such as attention deficit hyperactivity disorder (ADHD) and narcolepsy. However, they are also consumed recreationally for their euphoric effects.
Amphetamines have a unique chemical structure made up of a phenyl ring connected to an amino group through an ethyl chain. This basic structure can be modified in different ways to create various forms of amphetamines, each with its own effects.
These drugs can come in different versions, like racemic (which contains both types of molecules) or dextroamphetamine (which contains only one type of molecule). Each form affects the central nervous system in its own way.
While amphetamines can be found in nature, such as in the ephedra plant, the majority of amphetamines used today are synthetic. Synthetic amphetamines are produced through chemical synthesis in laboratories.
This allows for precise control over the composition and potency of the drug. Natural sources of amphetamines, like ephedra, have been traditionally used in herbal medicine but are less commonly encountered due to the availability of synthetic alternatives.
There are several types of amphetamines, each with its own effects on the body and mind. Some are prescribed for medical use, while others are often misused recreationally.
- Prescription Amphetamines: These are commonly prescribed to treat conditions like ADHD or narcolepsy. Examples include Adderall and Dexedrine, which contain mixed or pure forms of amphetamine compounds.
- Methamphetamine: Known as "meth," this is a more potent form of amphetamine with a higher potential for abuse. It is sometimes prescribed for ADHD or obesity but is more commonly known for its illegal use.
- Ecstasy (MDMA): While not exactly the same as traditional amphetamines, MDMA has similar stimulant effects and is often used recreationally for its euphoric and energizing effects.
How Amphetamines Work
Amphetamines have stimulant properties and are known for increasing alertness, attention, and energy. They are chemical messengers that transmit signals between nerve cells in the brain and influence neurotransmitters’ activity.
The three main neurotransmitters affected by amphetamines are dopamine, norepinephrine, and serotonin.
Dopamine is a chemical in your brain that’s linked to feelings of pleasure, motivation, and reward. Amphetamines can increase dopamine levels by making your brain release more of it and preventing it from being reabsorbed. They also stop the breakdown of dopamine, making its effects last longer. These changes can lead to heightened energy and focus, but they also come with risks if used outside of a medical setting.
Norepinephrine is a neurotransmitter that plays a role in the body’s “fight or flight” response. Like dopamine, amphetamines increase the release of norepinephrine and inhibit its reuptake, leading to increased levels of this neurotransmitter in the synapse.
This contributes to the stimulating effects of amphetamines, including increased heart rate, blood pressure, and alertness.
Serotonin is a neurotransmitter involved in mood regulation, sleep, and appetite. While amphetamines can influence serotonin, their impact on serotonin is less pronounced than that of dopamine and norepinephrine.
Effects of Amphetamines
Amphetamines, when misused or abused, amphetamines can have various effects on the body, both in the short term and long term. It’s important to note that using amphetamines without a prescription or in ways not directed by a healthcare professional can be dangerous and lead to serious health consequences.
Short Term Effects
- Increased Alertness and Energy: Amphetamines stimulate the central nervous system, leading to heightened alertness and increased energy levels.
- Euphoria: People may experience a sense of euphoria or intense pleasure due to dopamine release in the brain.
- Improved Focus and Concentration: Amphetamines can enhance concentration and focus, making them commonly prescribed for conditions like attention deficit hyperactivity disorder (ADHD).
- Elevated Heart Rate and Blood Pressure: These drugs can temporarily increase heart rate and blood pressure, which may pose risks, especially for young people with cardiovascular issues.
- Suppressed Appetite: Amphetamines often lead to a decreased appetite, which can result in weight loss.
- Dilated Pupils: Pupils may dilate as a physiological response to the stimulant effects.
- Insomnia: Difficulty sleeping is a common short-term side effect, as amphetamines can disrupt normal sleep patterns.
Long Term Effects
- Tolerance: The body may develop tolerance with prolonged use, requiring higher doses to achieve the same effects.
- Dependence and Addiction: Chronic use can lead to psychological and physical dependence and, in some cases, addiction.
- Cardiovascular Issues: Long-term use may contribute to cardiovascular problems, including hypertension and an increased risk of heart disease.
- Mental Health Issues: Amphetamines can exacerbate or contribute to mental health issues, such as anxiety, paranoia, suicidal thoughts, and depression.
- Cognitive Impairment: Prolonged use may affect cognitive function, including memory and executive functions.
- Malnutrition: Persistent appetite suppression can lead to nutritional deficiencies and malnutrition.
- Dental Problems: Chronic amphetamine use may result in dental issues, often referred to as “meth mouth.”
