However, statistical evidence suggesting a relationship between smoking and lung cancer began to emerge in the late 1920s, although scientific evidence of a causal relationship was not available until the mid-twentieth century. Since then, epidemiologists have collected evidence in large prospective and case-control studies to support a causal relationship between smoking and various diseases, chiefly cancer and cardiovascular and chronic respiratory diseases. As evidence on the negative effects of tobacco use accumulated, numerous organizations produced technical reports with programs and strategies for tobacco control that changed the course of public health. However, despite some success in implementing evidence-based policies and programs that have decreased smoking rates in recent decades, more effective strategies are needed to end the tobacco epidemic.
