http://www.oas.samhsa.gov/race.htm says none of that is true. Did you know that KOREANS are just over 3 times as likely as CHINESE to smoke cigarettes (in America).
Thanks for the link. I’ll dig out the stats I have from another source when I get the chance. Assuming the figures you provide are the correct ones, however, the difference in illicit drug use is not great e.g. 9.2 percent for blacks versus 8.1 for whites. Didn’t know about the cigarette use figures but I suppose it makes sense given the “driven” nature of high achievers.
