Depression, not PTSD, was independently associated with cannabis dependence in combat veterans
Among Israeli combat veterans using cannabis, those screening positive for dependence used more cannabis weekly and had higher moral injury scores, with depression (AOR 1.98) but not PTSD independently predicting dependence.
Quick Facts
What This Study Found
Veterans with cannabis dependence used significantly more cannabis per week and scored higher on moral injury "other" and "betrayal" subscales. After controlling for confounders, depression was significantly associated with dependence (AOR 1.98, 95% CI 1.05-3.72), while PTSD was not (AOR 1.19, 95% CI 0.56-2.54).
Key Numbers
Depression AOR: 1.98 (95% CI 1.05-3.72, p<0.05). PTSD AOR: 1.19 (95% CI 0.56-2.54, not significant). Dependent users consumed more grams per week and had higher moral injury scores.
How They Did This
Cross-sectional study of Israeli combat veterans discharged within the past 5 years. Compared those screening positive vs. negative for cannabis dependence on sociodemographic and clinical variables using SPSS.
Why This Research Matters
The finding that depression, not PTSD, independently predicted cannabis dependence in veterans challenges the common assumption that veterans use cannabis primarily to self-medicate PTSD.
The Bigger Picture
If depression is the key driver of cannabis dependence in veterans, treatment strategies should prioritize depression management alongside cannabis cessation support.
What This Study Doesn't Tell Us
Cross-sectional cannot determine causation. Screening tools rather than diagnostic interviews. Israeli military context may not generalize. Self-reported cannabis quantity.
Questions This Raises
- ?Would treating depression first improve cannabis dependence outcomes in veterans?
- ?Is the PTSD-CUD relationship truly non-significant, or underpowered in this sample?

What do these levels mean? →Frequently Asked Questions
Do veterans use cannabis because of PTSD?
Surprisingly, PTSD was not independently associated with cannabis dependence in this study. Depression was the stronger predictor, nearly doubling the odds of dependence.
What else predicted cannabis dependence in veterans?
Higher weekly cannabis dosage and higher moral injury scores (particularly around betrayal) were associated with dependence, alongside depression.
