The recent letter by one Roger Morgan was beyond preposterous. He states without reference that “[m]arijuana is also a major cause of psychosis, including schizophrenia and paranoia…. leading to… murder, suicides, addiction, birth defects, cancer, strokes, cardiac problems, more crime and traffic fatalities.” Briefly:
According to the journal Lancet Psychiatry, the results of a federally funded study published this June, medicinal cannabis has not caused an increase in marijuana use by adolescents. These results are not unique.
“Family genetics, rather than adolescent cannabis use, increases risk of schizophrenia,” according to a case control study published online in the journal Schizophrenia Research. Further, schizophrenics may use cannabis to self-medicate. It is true that people predisposed to schizophrenia should avoid cannabis.
Radley Balko writing in the Aug. 5, 2014, Washington Post notes, “Since marijuana legalization, highway fatalities in Colorado are at near-historic lows.”
Never miss a local story.
There is no causal link between cannabis use and violence. Many studies making this claim make no distinction between use and violence related to criminal gang-related sales. Further, two recent papers published in PLOS ONE and the Journal of Law and Economics found no increase in violent crime in medicinal cannabis states. Get the facts.
