The 20 pot users in the study, ages 18 to 25, said they smoked marijuana an average of about four days a week, for an average total of about 11 joints. Half of them smoked fewer than six joints a week. Researchers scanned their brains and compared the results to those of 20 non-users who were matched for age, sex and other traits.
The results showed differences in two brain areas associated with emotion and motivation - the amygdala and the nucleus accumbens. Users showed higher density than non-users, as well as differences in shape of those areas. Both differences were more pronounced in those who reported smoking more marijuana.
