MINNEAPOLIS (AP) — By following sets of twins from age 11 to adulthood, University of Minnesota researchers have found that cannabis use has few impacts on long-term cognitive abilities.
Out of 2,410 sets of identical twins from Minnesota, only 364 had differing cannabis use between siblings, making them eligible for the study. Following twins has allowed the researchers to observe differences in cannabis usage with fewer variables at play.
“The sample of twins is representative of the population of the whole state of Minnesota,” said Dr. Steve Malone, the study co-author and Institute for Child Development (ICD) researcher. “But I think it’s a really important feature of the design, that these samples are representative of the population of us as a whole.”
