What are Dexies?
“Dexies” is the common street name for dextroamphetamine (brand name Dexedrine), a potent central nervous system stimulant belonging to the amphetamine class. It is chemically similar to Adderall (which contains both amphetamine and dextroamphetamine) and Vyvanse (lisdexamfetamine).
Medical Uses:
When prescribed legitimately, dextroamphetamine is used to treat:
-
Attention Deficit Hyperactivity Disorder (ADHD): Helps improve focus, attention, and impulse control while reducing restlessness
-
Narcolepsy: A sleep disorder causing sudden, uncontrollable episodes of falling asleep during the day
-
Short-term weight loss (historically): Rarely prescribed for this purpose today
Why “Dexies” Are Abused:
The term “dexies” originated from the brand name Dexedrine (dextroamphetamine sulfate). People without ADHD sometimes take dexies to:
-
Stay awake longer to study or complete assignments (“study drugs”)
-
Enhance concentration and mental performance
-
Experience euphoria and increased energy
-
Suppress appetite for weight loss
-
Party or stay awake for extended periods
How Dexies Work (Mechanism of Action):
Dextroamphetamine increases the activity of two key neurotransmitters in the brain:
-
Dopamine: Associated with pleasure, reward, and motivation
-
Norepinephrine: Associated with alertness, energy, and focus
In people with ADHD, this increased signaling helps normalize brain function, improving memory, attention, and impulse control while actually producing a calming effect.
In people without ADHD, the same mechanism produces:
-
Heightened concentration and alertness
-
Reduced need for sleep
-
Euphoria and increased energy
-
Potential for dependence and addiction
Forms and Methods of Use:
| Method | Description | Additional Risks |
|---|---|---|
| Oral (swallowed) | Taking tablets/capsules as intended | Lower immediate risk but still addictive |
| Crushed and snorted | Powder inhaled through the nose | Nasal damage, bleeding, septum perforation |
| Crushed and injected | Dissolved in water and injected intravenously | Infection, vein damage, HIV/Hepatitis risk from needle sharing |
Immediate Side Effects:
-
Fast, irregular heartbeat (tachycardia)
-
Increased blood pressure
-
Decreased appetite and weight loss
-
Tremors and muscle twitching
-
Headaches and dizziness
-
Trouble sleeping (insomnia)
-
Dry mouth
-
Upset stomach, nausea
-
Anxiety, agitation, restlessness
-
Mood swings
Serious Adverse Effects:
-
Allergic reactions: Skin rash, hives, swelling of face/lips/tongue
-
Heart problems: Chest pain, tightness, high blood pressure, heart attack, stroke
-
Circulation problems: Cold or numb fingers/toes (Raynaud’s phenomenon)
-
Vision problems: Blurred vision
-
Confusion, hallucinations, paranoia (psychosis)
-
Seizures (especially in people with seizure history)
-
Malnutrition (from prolonged appetite suppression)
-
Aggressive or hostile behavior
Long-Term Health Consequences of Chronic Use:
| Health Issue | Description |
|---|---|
| Insomnia | Chronic difficulty sleeping |
| Malnutrition | Severe weight loss, vitamin deficiencies |
| Paranoia & Psychosis | Hallucinations, delusions, aggressive behavior |
| Cardiovascular damage | Heart attack, stroke, cardiomyopathy |
| Seizures | Increased seizure risk |
| Cognitive impairment | Memory problems, difficulty concentrating without the drug |
Dependence and Withdrawal:
Dextroamphetamine has high potential for both physical and psychological dependence. Even after short periods of use, withdrawal symptoms can occur.
Withdrawal Symptoms (when stopping or reducing use):
-
Severe fatigue and excessive sleepiness
-
Depression and mood swings
-
Intense drug cravings
-
Irritability and agitation
-
Insomnia or hypersomnia (sleeping too much)
-
Paranoia, hallucinations (in severe cases)
-
Suicidal thoughts
Overdose Signs and Symptoms:
| Sign | Description |
|---|---|
| Rapid, irregular heartbeat | Heart palpitations, chest pain |
| Extremely high blood pressure | Severe headache, vision changes |
| Hyperthermia | Dangerously high body temperature |
| Agitation and confusion | Psychomotor agitation, delirium |
| Seizures | Convulsions |
| Hallucinations | Seeing or hearing things not present |
| Panic | Extreme fear, aggression |
| Respiratory distress | Difficulty breathing |
| Loss of consciousness | Coma |
Overdose Response:
-
Call 911 or local emergency services immediately
-
Do not leave the person alone
-
Try to keep them calm and cool (overheating is dangerous)
-
If they have taken other substances (especially opioids), administer naloxone if available
-
Provide emergency responders with information about what was taken
Drug Interactions (Major):
| Drug Class | Interaction | Risk |
|---|---|---|
| MAO inhibitors (antidepressants) | Severe hypertensive crisis | Life-threatening |
| Alcohol | Masks intoxication, increased heart strain | Overdose, dehydration |
| Other stimulants (cocaine, MDMA) | Excessive CNS stimulation | Heart attack, seizure |
| Antidepressants (SSRIs) | Serotonin syndrome | Agitation, hyperthermia |
| Blood pressure medications | Reduced effectiveness | Uncontrolled BP |
Pregnancy and Breastfeeding:
-
Pregnancy: May cause premature birth, low birth weight, and neonatal withdrawal symptoms. Use only if benefit clearly outweighs risk.
-
Breastfeeding: Dextroamphetamine passes into breast milk and may cause irritability, poor feeding, and insomnia in infants. Not recommended.
Legal Status (By Jurisdiction):
| Country | Classification | Penalty for Possession (without prescription) |
|---|---|---|
| United States | Schedule II | Up to 1 year imprisonment + fine |
| United Kingdom | Class B | Up to 3 months imprisonment + fine (possession) |
| New Zealand | Class B | Up to 3 months imprisonment + $500 fine |
| Australia (WA) | Schedule 8 | Heavy fines, possible imprisonment |
Why “Dexies” Are Dangerous (Educational Message):
While dexies are legitimate prescription medications for ADHD and narcolepsy, using them without a prescription or outside prescribed guidelines carries serious risks:
-
You don’t know the dose or source – Diverted pills may be counterfeit or adulterated
-
“Study drug” myth persists – Studies show students who use stimulants without prescription actually have lower average grades than non-users
-
False sense of safety – Because they are pharmaceutical, users perceive them as “safer” than street drugs, but dependence and overdose risks are real
-
Polydrug use danger – Dexies are often combined with alcohol, which can mask intoxication and lead to severe dehydration, overdose, or alcohol poisoning
