Transitional cell carcinoma of the bladder tends to occur in older patients with a history of tobacco use. We recently evaluated and treated a 45-year-old man with a history of heavy marijuana use. The patient's only risk factor for transitional cell carcinoma was the inhalation of up to five marijuana cigarettes daily for more than 30 years. We present our case and review the literature.
