“We really didn’t find any support for a lot of the harms people worry about with legalization,” she said.
Researchers from CU Boulder, the University of Colorado Anshutz Medical Campus, and the University of Minnesota used data from the Institute for Behavioral Genetics and the Minnesota Center for Twin Family Research to study 4,000 twins to conduct the research. The twins came from Colorado, which has legalized cannabis for adult use and Minnesota, where it remains illegal. The researchers found that identical twins living in states where cannabis is legal used it 20% more frequently; but when they compared results and looked at cannabis use disorder, use of alcohol and illicit drugs, and psychotic behavior, the research found no correlation to legalization.
