Methylphenidate (Ritalin®) increases cigarette smoking in individuals with attention deficit/hyperactivity disorder (ADHD). Clinicians should consider non-stimulant options or counsel patients about this risk.
Area of Science:
- Neuroscience
- Psychiatry
- Pharmacology
Background:
- Methylphenidate (Ritalin®) is a common treatment for attention deficit/hyperactivity disorder (ADHD).
- Previous research indicates methylphenidate may increase smoking in individuals without psychiatric diagnoses.
- The effect of methylphenidate on smoking in individuals diagnosed with ADHD remains unclear.
Purpose of the Study:
- To investigate the acute effects of methylphenidate on cigarette smoking in adults with ADHD.
- To assess dose-dependent responses to methylphenidate regarding smoking behavior.
Main Methods:
- A within-subjects, repeated measures design was employed.
- Nine adult smokers with ADHD (and nicotine dependence) received placebo or methylphenidate (10, 20, 40 mg).
- Smoking behavior (cigarettes, puffs, carbon monoxide) and caloric intake were measured over 4 hours post-ingestion.
Main Results:
- Methylphenidate significantly increased the number of cigarettes smoked.
- Total puffs and carbon monoxide levels were elevated following methylphenidate administration.
- Consumption of food items and caloric intake decreased with methylphenidate treatment.
Conclusions:
- Acute methylphenidate administration enhances cigarette smoking in individuals with ADHD.
- Findings align with previous studies in non-psychiatric populations.
- Clinicians should consider counseling ADHD patients who smoke or exploring non-stimulant alternatives.

Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings.
Stimulants
Cocaine can be administered via snorting, injection, or smoking. It primarily functions by blocking the reuptake of dopamine, resulting in a euphoric high characterized by an intense sensation of happiness and...
Drugs Acting on Autonomic Ganglia: Stimulants
Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating sympathetic or...
Adrenergic Agonists: Mixed-Action Agents
Ephedrine and pseudoephedrine lack a catecholamine group, making them less susceptible to degradation by metabolic enzymes. They have increased oral bioavailability and lipophilicity, resulting in a longer duration of action. Their response is reduced by...
Adrenergic Agonists: Indirect-Acting Agents
One mechanism involves depleting stored catecholamines by displacing them from synaptic vesicles. These agents, known as "displacers," are transported into vesicles at the expense of noradrenaline. Examples include amphetamine and tyramine, which lack a catechol moiety, resulting in prolonged action, improved oral bioavailability, and...
