The 29-year-old requesting stimulant treatment for 'adult ADHD'
A 29-year-old man presents to a private clinic asking for 'the medication for adult ADHD'. He describes lifelong difficulty concentrating, but on questioning he has never had a structured assessment, and his school reports were unremarkable. He has used cocaine at weekends for two years and says it 'calms me down'. He drinks heavily on Fridays. He is currently working and has no forensic history. He has already found a clinic online that will prescribe stimulants after a 20-minute video call, and he asks you to do the same. He has no GP records available. He becomes irritated when you suggest a fuller assessment.
1. How do you approach the diagnostic question, and what is the role of his substance use?
Read the worked answer
ADHD requires evidence of symptoms before age 12, in more than one setting, causing impairment, and not better explained by another condition. His childhood school reports are unremarkable, which argues against it, but they are not definitive. Obtain collateral information: a parent or sibling, school records, and old GP notes. Use a structured interview and validated rating scales, and assess for comorbid anxiety, depression, sleep problems and substance use. His cocaine use is central: stimulants can 'calm' people with ADHD, but cocaine also produces that effect in people without it, so it does not confirm the diagnosis. Heavy weekend alcohol and cocaine use can cause attentional problems and mood disturbance, and prescribing a stimulant to someone with active stimulant misuse risks diversion, dependence and cardiac harm. The absence of records and the request for a rapid video diagnosis are red flags for a shortcut. Explain that a proper assessment takes time, and that a diagnosis made to justify a prescription is not a diagnosis.
2. How do you respond to his request and his irritation, and what would you offer?

Acknowledge his frustration and the real impairment he describes; do not moralise about his cocaine use, which would end the conversation. Explain that you will not prescribe on a 20-minute call, not because you doubt him but because the wrong diagnosis or an unsafe prescription could harm him. Offer a structured assessment over one or two appointments, with a collateral history and a urine drug screen, and explain that treatment of any substance use problem may itself improve concentration. If ADHD is confirmed, discuss non-stimulant options and the monitoring required for stimulants, including cardiovascular checks and review of misuse risk. If it is not confirmed, explain what else might explain his difficulties and offer help for that. Set boundaries clearly: you will not prescribe today, and you will not collude with a clinic that does. Document the discussion, his response, and the plan. If he leaves angrily, offer a route back; a patient who feels heard is more likely to return than one who feels judged.
