Marijuana Use Worsens PTSD Symptoms in Veterans
A 2015 study by Samuel T. Wilkinson and colleagues in the Journal of Clinical Psychiatry reports that among war veterans who completed a special treatment program for post-traumatic stress disorder, those who continued or began using marijuana after treatment had more severe PTSD symptoms, were more violent, and used drugs and alcohol more often. Those who stopped using marijuana or never used it had the lowest levels of PTSD symptoms in the study.
Editor’s Note: Scientific information about marijuana is almost never reported in the media. Evidence of the adverse effects of heavy marijuana use are robust and consistent.
Some of these include:
- A doubling of the risk of psychosis compared to non-users. People with a common variation in the enzyme COMT, which metabolizes dopamine, have an even higher rate of psychosis.
- An increased risk of bipolar disorder onset.
- A worse course of bipolar disorder.
- An increased risk of schizophrenia.
- Memory deficits that remain even after marijuana use has ceased.
- Loss of motivation (exactly what someone with depression doesn’t need).
- Anatomical changes in brain structures.
- A worse course of PTSD and increased violence in those with PTSD.
Bottom line: Those who say marijuana is benign may be ill-informed. People with mood disorders, proneness to paranoia, or PTSD should stay away from marijuana.
