Cannabis is contraindicated in individuals with which condition?

• A. Schizophrenia, Mental Illness
• B. Diabetes
• C. Asthma
• D. Hypertension

Answer: (A)

Cannabis use is contraindicated in individuals with schizophrenia and mental illness because it can worsen psychotic symptoms and trigger relapses. The cannabinoids affect brain pathways that modulate dopamine, which are already involved in psychosis; this can lead to increased hallucinations, delusions, and disorganized thinking, and may interfere with antipsychotic treatment or adherence. For other conditions listed, there isn’t an absolute contraindication: diabetes doesn’t inherently bar cannabis use, though it can influence appetite or blood sugar management; asthma may be affected by inhaled smoke but alternatives exist; hypertension can have acute cardiovascular effects, but cannabis isn’t universally contraindicated in all hypertensive patients.
