Both drugs can increase energy and focus, but they carry different risks. Methamphetamine is more potent and addictive, leading to severe health issues. Amphetamines, when used correctly under medical supervision, are safer.
Let’s discuss the deeper details of Methamphetamine vs Amphetamine in this article.
Key Takeaways
- Amphetamines are used medically for treating ADHD.
- Methamphetamine is more potent and has higher abuse potential.
- Both have significant health risks but differ in effect and legal status.
Methamphetamine vs Amphetamine: Differences
Chemical Structure:
Methamphetamine and amphetamine both stimulate the central nervous system. They increase levels of dopamine and norepinephrine in the brain. Methamphetamine has a more complex chemical structure, making it pass into the brain faster.
Potency:
Methamphetamine is stronger than amphetamine. It releases more dopamine in the brain, creating a more intense effect. This leads to a higher potential for abuse and addiction.
Effects on the Brain:
Methamphetamine causes more significant changes in brain function. It’s linked to more severe neurotoxicity. This can result in long-term damage to brain cells. Amphetamine is less damaging to the brain compared to methamphetamine.
Feature | Methamphetamine | Amphetamine |
---|---|---|
Potency | Higher | Lower |
Brain Impact | More severe | Less severe |
Addiction Risk | Higher | Lower |
Medical Use:
Amphetamine is commonly prescribed for ADHD and narcolepsy. Methamphetamine has limited medical use, often in severe ADHD cases and obesity treatments under strict supervision.
Euphoria:
Methamphetamine produces stronger feelings of euphoria. This is due to the higher dopamine release. Amphetamine still induces euphoria but to a lesser degree.
Duration of Effects:
The effects of methamphetamine last longer. It can stay active in the body for up to 12 hours. Amphetamine effects usually last between 4 to 6 hours.
Legality and Availability:
Both substances are controlled. Methamphetamine is often illegal, while amphetamine is available by prescription for medical reasons.
Amphetamine vs Methamphetamine: Similarities

Both amphetamine and methamphetamine are central nervous system stimulants.
They are classified as Schedule II substances, meaning they have a high potential for misuse but are also available by prescription.
Both drugs are used to treat ADHD (Attention Deficit Hyperactivity Disorder) and narcolepsy.
Prescription medications like Adderall, Ritalin, and Vyvanse contain amphetamine or its salts. Methamphetamine is sometimes prescribed as Desoxyn.
Medical Uses
These substances help increase focus and attention in ADHD patients. They also help stay awake for those with narcolepsy.
In some cases, they may be used to treat obesity, as they can reduce appetite.
Dosage and Administration
Both are taken orally in prescribed doses.
Risks and Disorders
Amphetamine use disorder and substance use disorder can develop with both drugs due to their potential for misuse.
They are controlled substances per FDA rules, requiring careful prescription and monitoring.
Effects on the Body
You might notice increased heart rate, elevated blood pressure, and reduced appetite when using these medications. They work by increasing the levels of certain neurotransmitters in the brain.
In simpler terms, they make you feel more awake and focused.
While these drugs have similar medical benefits, you should use them only as prescribed due to their high potential for misuse and addiction.
Health Risks and Side Effects

Methamphetamine and amphetamine can have serious health risks. These risks include both short-term and long-term health impacts, as well as issues with dependency and withdrawal symptoms. Understanding the differences in these risks can help in making informed decisions about use and treatment.
Short Term and Acute Side Effects
Both methamphetamine and amphetamine can cause short-term side effects. These impacts usually appear soon after use. Some common effects include:
- Increased heart rate and blood pressure: This happens within minutes of taking the drug.
- Loss of appetite: You might not feel hungry and could lose weight quickly.
- Euphoria: Users often feel extremely happy or energetic.
Serious side effects can also occur. These can include headaches, nausea, and dizziness. In extreme cases, you might experience stroke, heart attacks, or even death. Users can also develop paranoia, anxiety, and hallucinations shortly after taking these drugs.
Chronic Use and Long-Term Health Impacts
When used over a long time, both drugs can have severe health impacts. Chronic use can lead to psychosis, a severe mental disorder where you might lose contact with reality. Other long-term side effects include:
- Insomnia: You may have trouble sleeping.
- Weight loss and malnutrition: Continuous lack of appetite can weaken your body.
- High blood pressure: Ongoing use can lead to hypertension and increase the risk of heart disease.
Over time, you could develop cognitive issues, such as memory problems and difficulty thinking clearly. Additionally, methamphetamine can cause more severe effects like skin sores and severe dental problems (often called “meth mouth“). Chronic users of both drugs might also experience mood swings, aggression, and depression.
Dependency, Addiction, and Withdrawal
Both methamphetamine and amphetamine are highly addictive. Using them regularly can lead to physical dependence, making it hard to stop using without help. Signs of addiction include:
- Cravings: A strong urge to use the drug.
- Increased use: Needing more of the drug to feel the same effects.
- Problems in daily life: Difficulties at work, school, or in relationships.
Withdrawal symptoms can be severe, including fatigue, depression, and increased appetite. You might also experience irritability, anxiety, and sleep disturbances. Professional treatment and counseling, including cognitive behavioral therapy and support groups, are usually necessary for recovery. Some treatments may include medications like antidepressants to manage symptoms.
Treatment also focuses on mental health support to address issues like depression and anxiety, which often accompany addiction. With the right help, recovery is possible, although it can be a long and challenging process.
Legal Aspects and Societal Impact

Methamphetamine and amphetamine are both powerful stimulants that have significant legal and societal impacts. Their regulation differs between countries, and their use comes with serious public health concerns.
Regulations and Control Measures
Both methamphetamine and amphetamine are controlled substances in many countries. Methamphetamine is usually classified as a Schedule II drug, indicating a high potential for abuse and limited medical use. Amphetamine, used in medications like Adderall, is also tightly regulated due to its potential for addiction.
Laws regarding possession of methamphetamine are stricter, with severe penalties for illegal manufacture and distribution. Amphetamines used without a prescription can lead to penalties as well. Illicit drugs like methamphetamine face stringent restrictions to curb their spread, while prescription drugs like amphetamines are monitored closely.
Impact on Public Health and Safety
Methamphetamine abuse has devastating effects on communities. Public health is severely impacted due to the high addiction rates and difficulty of quitting. Methamphetamine users often suffer from severe health problems, including heart issues and mental disorders.
The societal impact is alarming with increased crime, family disintegration, and healthcare costs. Amphetamine misuse also poses health risks but is less likely to cause the same level of public safety concerns as methamphetamine. Proper regulation and control significantly affect minimizing these impacts.
