Because of the heavy concentrations of DDT and other endocrine disrupting pesticide residues we recently detected contaminating popular tobacco brands, I’ve been thinking a lot about the fact that beginning with the 1950s every tobacco product being smoked, puffed, dipped or chewed in America had extremely heavy concentrations of organochlorine pesticides. Heavy use of xenobiotic “crop protection” agents for tobacco began in the 1950s with DDT and quickly included aldrin, endrin, dieldrin, chlordane and other byproducts of wartime toxic gas research.
With that in mind, please check this:

Maternal o,p′-DDT predicted daughters’ breast cancer (odds ratio fourth quartile vs first = 3.7, 95% confidence interval 1.5–9.0). Mothers’ lipids, weight, race, age, and breast cancer history did not explain the findings.

“Considering the patterns we observed, working backward to determine when a woman first came into contact with the chemical could help inform early detection and treatment of DDT-associated breast cancer.”
Women who were born roughly between 1955-1980 to mothers who smoked (or dipped or chewed) any of the popular tobacco brands of the times were heavily exposed to DDT and other organochlorines in the womb and probably throughout early childhood as Mommy smoked to get rid of all that pregnancy weight and then kept on smoking, maybe in secret, just a little, because it calmed her nerves.
A confidential industry study done in 1972 that I located in the Tobacco Settlement files reported an average of almost 6 mg/kg total DDT over all the brands they tested anonymously. The report ended with a hope that DDT concentrations would be dropping in the future (it had just been banned worldwide for the first time in 1972), and a warning that the data must be kept secret.
But when you look at what we found in tobacco products in 2018 you can see how little progress has been made. While there is only one instance of DDT contamination here it is extreme, and as you can see there are several rather extreme concentrations of other hazardous endocrine disrupting pesticide residues here even in this small sample. There are also residues of pesticides for which no data exist – their effects are unknown. It’s a crap shoot with human lives rolling snake eyes.
