The word “statistical association” has been condensed to “association” in a following preference of highlights from a NASEM report. It should be kept in mind that a statistical organisation might or might not yield justification of a causal relationship. In other words, a statistical organisation between smoking pot and something else does not mean that smoking pot causes that something else. It means that a dual things seem together some-more mostly than is expected to occur by chance. Smoking pot might be a means and it might not.
