Jan. 2, 2021 – “Make no mistake about it, smoking marijuana daily carries with it very real potential for addiction. The National Institute on Drug Abuse estimates that between 9% and 30% of those who use regularly will develop marijuana use disorder,” says Dr. Mary Gay. “I have observed significant negative effects on clients who habitually use marijuana including reduced academic performance, job loss, legal consequences, depression, anxiety, and in several cases, psychotic symptoms requiring hospitalization.” … “Compared with placebo, marijuana cigarettes cause increases in heart rate, systolic and diastolic blood pressures, and forearm blood flow via increased sympathetic nervous system activity,” says Dr. Kim Langdon. “In addition, marijuana has been associated with triggering heart attacks in young male patients. Smoking marijuana has been shown to increase the risk of MI onset by a factor of 4.8 for the 60 minutes after marijuana consumption, and to increase the annual risk of MI in the daily cannabis user from 1.5% to 3% per year.” …”Functional MRI studies have also revealed functional and structural changes in brain areas involved in reward processing after chronic cannabis use and in the processing of emotion,” says Dr. Langdon. “Some studies show a higher incidence of schizophrenia in chronic adolescent and teenage use of marijuana.”
