The U.S. Department of Transportation report suggests that while cannabis could potentially impair driving skills, its findings in other research suggest drivers under the influence of cannabis are actually more cautious. “Subjects in most of the simulator and instrumented-vehicle studies on marijuana are driving typically drive slower, follow other cars at greater distances and take fewer risks than when sober,” the report said. http://www.nhtsa.gov/staticfiles/nti/pdf/812117-Drug_and_Alcohol_Crash_Risk.pdf

A Controlled Family Study of Cannabis Users with and without Psychosis Harvard study published in 2014:
Evidenced that teen cannabis consumption is not lead to the development of schizophrenia later in life. The study compared families with a history of schizophrenia to those without. The study also examined non-psychotic cannabis consumers and non-consuming participant controls.
The results of the current study suggest that having an increased familial morbid risk for schizophrenia may be the underlying basis for schizophrenia in cannabis users and not cannabis use by itself.
