An identical claim was shared on Facebook here, here, here, and here.
The claim, however, is false.
A spokesperson for the CDC told AFP that by 1958, the US government had determined that smoking was a causative factor in lung cancer.
In the 1950s, the CDC was named the Communicable Disease Center and focused on communicable diseases.
Non-communicable diseases, such as cancer and related risk factors, were addressed by the U.S. Department of Health, Education, and Welfare (HEW), the precursor to the current Department of Health and Human Services.
"As noted in the 2000 U.S. Surgeon General's Report, several activities by then Surgeon General, Dr. Leroy Burney, who reported to the Director of HEW, reinforced the U.S. Government's stance on the growing scientific association between smoking and cancer," the spokesperson said in an email on July 30, 2020.
"Specifically, the report notes: 'The Surgeon General first brought the Public Health Service into the scene by establishing a scientific study group in 1956 to appraise the effects of smoking on health. The study group determined that there was a causal relationship between excessive smoking of cigarettes and lung cancer. Surgeon General Leroy E. Burney issued a statement in 1957 that 'the weight of the evidence is increasingly pointing in one direction: that excessive smoking is one of the causative factors in lung cancer.'"
