Cannabis & Schizophrenia Linked to Shooting

The recent shooting of a US Congresswoman is directly linked to long-term cannabis use and schizophrenia of the arrested offender.

Cannabis is not a harmless recreational drug but is linked to the serious mental disorder of paranoid schizophrenia.

The offender had a long history of cannabis use starting from school.

The relationship of schizophrenia to violent behavior is almost completely determined by drug use.

The coexistence of substance use and schizophrenia increases the risk of violence more than three fold.

The combination of serious mental illness and substance use worsens both disorders.

The linking of long term cannabis use and severe mental illness to the attempted murder of an elected official in the United States confirms the clear medical research that violence and cannabis use are linked.

Paranoid delusional schizophrenia from cannabis use disorganizes the users’ world so that it bears little relationship to reality.

This is why public figures like elected officials are a target.

In fact cannabis use not only makes the symptoms of mental illness worse but it reduces the effectiveness of treatments.

Reducing the use of cannabis would pay off in a safer community and lessen the risks to high profile community representatives.

Effective court supervised early intervention drug rehabilitation that leads to a drug free life makes our leaders safer.
