No smoking gun: In individual patients, it is hard to pinpoint which carcinogenic exposure (if any) caused their cancer. Carcinogens usually don't leave a telltale sign on the cancer cell itself. We must then rely on statistical inferences from studies of large groups of people. Though less well studied than tobacco, studies estimate the risk of lung cancer is 2x higher in pot smokers. Car crashes also go up ~4x.
