One of my most memorable was a patient with asthma that requested a letter she could take to her landlord because her neighbors were smoking pot. Patient states smoke would come though her thin walls into her room causing her to have an asthma exacerbation. She wanted a doctors note indicating the medical necessity of protecting her from this environmental hazard. She was hoping that the letter would help motivate her landlord to kick out the neighbors or reinforce the wall to stop the smoke from entering. I initially told the patient that I didn't think my note would help the way she thought it would but she persisted. Eventually I had the patient sign a disclosure form and I wrote a quick one paragraph letter general letter stating the patient had a medical condition that is benefited from limiting exposure to noxious stimulants. I signed the letter, gave it to the patient, and never heard back.
