摘要：All schools of medicine in the United States (N = 128) and Canada (N = 16) were surveyed by telephone to determine if they had instituted policies to restrict smoking. Some policy restricting smoking was reported by 80.56 percent of US schools (N = 103) and by 93.8 percent of Canadian schools (N = 15). However, only 52.3 percent of US (N = 67) and 56.3 percent of Canadian medical schools (N = 9) indicated they had formal written policy statements. Only 13 percent of US schools and 19 percent of Canadian schools had banned smoking totally.
