Amphetamines are central nervous system stimulants that increase dopamine and norepinephrine signaling. The class includes prescribed products such as mixed amphetamine salts, dextroamphetamine, lisdexamfetamine, and methamphetamine, as well as illicitly manufactured amphetamine-type stimulants. Medical use follows a diagnosis, a prescribed dose, and ongoing monitoring; misuse means taking a larger dose, using another person's medication, changing how it is taken, or using it to become intoxicated.
What Are Amphetamines and How Are They Used?
Amphetamines are synthetic stimulants used medically for conditions including ADHD and narcolepsy and used nonmedically for wakefulness, energy, or euphoria. The Drug Enforcement Administration classifies many amphetamine products as Schedule II because they have accepted medical uses and a high potential for misuse and severe dependence.
Prescription tablets and capsules are normally swallowed. Nonmedical use includes swallowing unprescribed pills, crushing and snorting tablets, injecting dissolved material, or smoking crystalline methamphetamine. Faster delivery intensifies reinforcement and toxicity, while any route produces overdose when cardiovascular, neurologic, or temperature-regulation effects become severe.
Adderall contains mixed amphetamine salts prescribed for ADHD and narcolepsy; nonmedical use, physical dependence, and stimulant use disorder describe different relationships to the medication.
Concerta vs Adderall compares methylphenidate with mixed amphetamine salts by active molecule, release profile, approved indications, and misuse risk; prescribed use and expected physical dependence alone do not establish stimulant use disorder.

How Do Amphetamines Affect the Brain and Body?
Amphetamines increase catecholamine activity, which raises alertness and concentration while also increasing pulse, blood pressure, temperature, and strain on the cardiovascular system. Therapeutic effects and adverse effects depend on the specific product, dose, route, other substances, and the person's medical history.
Acute adverse effects include insomnia, appetite suppression, dry mouth, tremor, anxiety, irritability, and rapid heart rate. Severe toxicity includes chest pain, dangerously high blood pressure or temperature, arrhythmia, seizure, hallucination, psychosis, stroke, or collapse. Call 911 for those symptoms. Naloxone does not reverse stimulant toxicity, but it should still be given when opioid exposure is possible because counterfeit stimulant tablets and illicit stimulants sometimes contain fentanyl.
What Are the Signs of Amphetamine Misuse and Addiction?
Amphetamine misuse changes how the drug is obtained or taken; stimulant use disorder adds impaired control, craving, functional harm, tolerance, or withdrawal. A clinician diagnoses the disorder from the pattern and consequences of use rather than from a single symptom or drug-test result.
- Loss of control: taking more than intended, repeatedly failing to reduce use, or spending substantial time obtaining and recovering from the drug.
- Dose escalation: needing larger or more frequent amounts to reproduce the same effect.
- Functional change: missed work or school, deteriorating relationships, financial problems, or abandoning normal activities.
- Stimulant cycle: prolonged wakefulness and activity followed by exhaustion, increased sleep, low mood, and craving.
- Unsafe behavior: using unprescribed pills, combining stimulants, or continuing despite cardiovascular or psychiatric symptoms.
How Are Amphetamine and Methamphetamine Different?
Methamphetamine is an amphetamine-type stimulant whose chemical structure and pharmacokinetics produce longer-lasting central nervous system effects than cocaine. Prescription methamphetamine exists as Desoxyn, but most methamphetamine discussed in addiction care is illicitly manufactured crystal or powder. The DEA notes that methamphetamine remains in the central nervous system longer than cocaine, while illicit supply introduces unpredictable purity and fentanyl exposure.
Crystal methamphetamine addiction adds a longer stimulant exposure, a pronounced crash, dental and skin complications, psychosis risk, and a distinct overdose-response profile.
What Happens During Amphetamine Withdrawal?
Amphetamine withdrawal commonly includes fatigue, depressed or irritable mood, increased sleep or insomnia, increased appetite, slowed movement, vivid dreams, and intense craving. Symptoms often begin with a crash after stimulant effects end and then improve over days to weeks; mood, sleep, and craving sometimes persist longer.
Withdrawal is primarily a psychiatric and behavioral safety concern rather than the seizure-driven syndrome associated with alcohol or benzodiazepines. Severe depression, psychosis, or suicidal thinking requires urgent assessment. Call or text 988 for suicidal thoughts, and call 911 for immediate danger or a medical emergency.
How Is Amphetamine Addiction Treated?
Amphetamine addiction treatment combines clinical assessment, behavioral therapy, recovery support, and care for co-occurring medical or psychiatric conditions. No medication is FDA-approved specifically for stimulant use disorder. The ASAM/AAAP guideline identifies contingency management as a primary component of treatment, with cognitive behavioral therapy, the Community Reinforcement Approach, and the Matrix Model among the evidence-supported approaches used alongside it.

Level of care follows severity and safety. A hospital or withdrawal-management provider handles unstable medical or psychiatric symptoms. Residential care supplies a controlled living environment when outpatient participation is not safe or practical. Partial care, intensive outpatient, and standard outpatient programs provide decreasing amounts of weekly structure as stability improves.
When prescription stimulant misuse produces impaired control or continued use despite harm, prescription drug rehabilitation addresses the substance-use pattern, co-occurring symptoms, and appropriate level of care.
Once a stimulant use disorder has been established, intensive outpatient addiction treatment provides recurring therapy and monitoring while a person continues living at home. Valley Spring Recovery Center assesses adults for partial care, intensive outpatient, outpatient, and telehealth services in Norwood, New Jersey, and coordinates detoxification or residential placement when a different level is required.
