Cannabis vaping for sleep and anxiety in a lonely widower
Mr. B is a 68-year-old retired teacher whose wife died 14 months ago. He moved to a new city to be near his daughter but knows few people and spends most days alone. For the past year he has vaped cannabis three to four times daily to manage anxiety and insomnia, and he drinks two beers most evenings. He wants to stop cannabis because he is spending about $400 per month and feels foggy, but he fears worsening insomnia and anxiety. His PHQ-9 score is 11, GAD-7 score is 9, and blood pressure is 138/84 mm Hg. He has no history of seizures or alcohol withdrawal and takes no medications. He says his daughter is worried but he does not want to be a burden. He asks whether he can quit cold turkey and what he should do about sleep.
1. How would you assess and counsel Mr. B about his cannabis use, including whether he can quit abruptly?

Begin with nonjudgmental screening: quantity, frequency, route, reasons for use, consequences, and criteria for cannabis use disorder. Daily vaping three to four times/day with inability to cut down and continued use despite fog suggests a moderate disorder. Use motivational interviewing: ask permission, explore pros and cons, affirm his desire to stop, and elicit his own reasons (cost, cognition, daughter). He can quit abruptly, but abrupt cessation is associated with withdrawal; a planned quit date with a taper may be easier. Assess for concurrent alcohol use and mental health. Do not simply say just stop. Offer behavioral support (CBT, motivational enhancement) and treat anxiety and sleep concurrently. Set follow-up within 1–2 weeks.
2. What withdrawal symptoms and sleep problems should he expect, and how would you manage them without substituting another substance?

Warn him about withdrawal: irritability, anxiety, insomnia, decreased appetite, craving, headache, and vivid dreams, peaking in the first week and improving over 2–4 weeks. Sleep will be disrupted; do not substitute alcohol. Use CBT-I, stimulus control, a consistent wake time, and limited naps. Avoid caffeine after noon. If anxiety is severe, treat with evidence-based psychotherapy; there is no FDA-approved medication for cannabis use disorder, and benzodiazepines are not appropriate for withdrawal. Monitor for depression and suicidal ideation. If he develops severe agitation, psychosis, or suicidal thoughts, refer urgently. Encourage him to tell his daughter and enlist support.
3. How would you address his social isolation and grief, and what follow-up would you arrange?

Loneliness and grief are drivers of his use. Screen for depression and complicated grief. Use social prescribing: grief support group, senior center, library, faith community, volunteer or walking group, and a standing weekly call with his daughter. Schedule one social contact per week and build from there. Address transportation and hearing. Consider referral to a therapist for grief-focused CBT. Follow up in 2 weeks and again at 1 month; ask about cannabis, alcohol, sleep, and mood. Coordinate with his daughter with permission. Frame social connection as treatment, not an optional extra.
