Researchers have found that those with high childhood IQs are more prone to illegal drug use as adults. But what does this correlation really mean?
Two major papers have found a positive correlation between high childhood IQ and adult drug use.
The first was published in 2011 (Intelligence across childhood in relation to illegal drug use in adulthood: 1970 British Cohort Study). The second was published in 2012(Intelligence quotient in childhood and the risk of illegal drug use in middle-age: the 1958 National Child Development Survey). Both were co-authored by James W. White PhD and all of the data for both research papers comes from The Centre for Longitudinal Studies (CLS), a research council operating from the Department for Quantitative Social Science, Institute of Education, at the University of London.
