Does Marijuana Abuse Lead to Schizophrenia?

In 2014, the Substance Abuse and Mental Health Services Administration reported cannabis—otherwise known as marijuana—is the most commonly-used illicit drug in the United States. Unfortunately, this drug is being abused by large numbers of youth and adults from Fresno, Calif., to the East Coast.

Though drug rehab centers can help treat addictions to cannabis, many are not aware of the dangerous effects of abusing marijuana. These harmful effects include impaired body movement, reduced memory and temporary hallucinations and paranoia. Furthermore, for those who live with schizophrenia, abusing cannabis can worsen their symptoms.

A study conducted by Robert Power—a genetic psychiatrist at King’s College in London—states, “There is a well-established link between people who use cannabis and schizophrenia.” Moreover, the study’s findings indicate that those who live with schizophrenia are more likely to abuse marijuana in greater quantities. Individuals who abuse marijuana in large amounts may need the lifesaving services of drug rehab centers in the future.

However, other researchers such as Lynn DeLisi—a Harvard University psychiatry professor—are not convinced of this claim. DeLisi’s research concerning cannabis and schizophrenia show “no difference in family history of schizophrenia between people who smoke weed and people who don’t,” reports The Verge. DeLisi suggests further testing of individuals who smoke and those who don’t, both claiming a family history of schizophrenia.

Though there is more research to conduct to explain the link between schizophrenia and cannabis abuse, individuals across the nation are still heavily abusing marijuana. Whether abused in the parks of Fresno, in the schoolyard or behind locked doors, marijuana is deteriorating the mental and physical health of many across the nation.

It’s important for those battling an addiction to marijuana to seek necessary support through trusted individuals and drug rehab centers. Many in Fresno and across the nation have received the help needed to move on from addiction and regain their footing.
