People with post-traumatic stress disorder (PTSD) who use medical marijuana have fewer depressive episodes and lower rates of suicidal thoughts than those who don’t, according to new research. Despite the common belief that cannabis increases the risk of suicide, especially in young people, this study suggests the opposite may be true for those with PTSD.
Let’s take a closer look at what the study shows about how cannabis may help reduce suicidal ideation in PTSD patients and why the link between cannabis use and suicide isn’t as straightforward as some think.
A study highlighted in the Journal of Psychopharmacology analyzed results from Statistics Canada’s 2012 Community Health Survey to investigate the relationship between cannabis use and PTSD. The results were clear: PTSD patients who used cannabis faced less depression and suicidal ideation when compared to people who didn’t.
Out of the 24,000 people surveyed, 28.2% of PTSD patients reported using cannabis, compared to just 11.2% of individuals without PTSD. Most notably, those with PTSD who didn’t use cannabis were seven times more likely to have a major depressive episode and 4.3 times more likely to have suicidal thoughts.
When looking at the risk of suicide among PTSD patients, it’s essential to consider the role of SSRIs (selective serotonin reuptake inhibitors) and other psychotropic medications. These drugs are frequently prescribed to manage PTSD symptoms, but they often come with a well-documented side effect: suicidal ideation.
In fact, numerous studies have shown that people taking SSRIs or other antidepressants, especially younger patients, may be at an increased risk of developing suicidal or homicidal thoughts. This raises serious questions about the simplistic blame placed on cannabis for mental health issues like suicide.
With so many PTSD patients prescribed these medications, it becomes difficult to separate the impact of cannabis from that of psychotropic drugs. The correlation between these medications and an increased risk of suicidal ideations suggests that the issue is more complex than cannabis use alone. Therefore, there is a need for a more in-depth understanding of all factors at play, rather than attributing suicidal ideation solely to marijuana use, especially when other powerful medications are involved.
It is also worth noting that for patients with psychiatric histories, self-medication with cannabis is a common coping mechanism. Many turn to cannabis as a way to manage symptoms of anxiety, depression, and PTSD when conventional treatments fall short. While this may provide relief, it complicates the conversation around cannabis and suicidal ideation.
Without considering the impact of these powerful drugs, it’s easy to draw misleading conclusions about the effects of cannabis. This complex relationship between cannabis, mental health, and other medications reinforces the need to identify all contributing factors rather than placing sole blame on cannabis use.
Cannabis interacts with the body’s endocannabinoid system (ECS), which plays a key role in regulating the mood, memory, and stress responses that are profoundly affected by PTSD. The ECS consists of cannabinoid receptors, such as CB1 and CB2, found throughout the brain and body. These receptors are involved in modulating the release of neurotransmitters that influence emotional processing and stress resilience.

One of the primary areas of the brain impacted by PTSD is the amygdala, responsible for the “fight or flight” response and emotional reactions, particularly fear. In people with PTSD, the amygdala tends to be overactive, leading to heightened anxiety and flashbacks. Cannabinoids, particularly THC, can bind to CB1 receptors in the amygdala, helping to calm this overactivity and reduce anxiety, which can be critical for those who feel overwhelmed by stress and traumatic memories.
Another important region is the hippocampus, which is involved in memory formation and retrieval. PTSD patients often experience intrusive memories and flashbacks, which can contribute to a sense of hopelessness and despair. Cannabis may help reduce the intensity and frequency of these traumatic memories by influencing the hippocampus, providing relief from the emotional weight these memories carry.
Lastly, the prefrontal cortex, which regulates decision-making, emotional responses, and impulse control, also plays a significant role in PTSD. Cannabis may help adjust activity in this area, improving emotional regulation and stress management. As a result, people gain a better sense of control over mood and mental health.
Youth dealing with PTSD are especially vulnerable to feelings of depression, hopelessness, and suicidal ideation, often stemming from the overwhelming emotional burden of trauma.
By interacting with these key areas of the brain, cannabis may help reduce the heightened anxiety, emotional reactivity, and intrusive thoughts that fuel suicidal feelings. In other words, by calming the brain’s stress response and regulating mood, cannabis may reduce the severity of depressive episodes and the frequency of suicidal ideation in youth with PTSD.
Former U.S. Department of Veterans Affairs Secretary David Shulkin has advocated for more research into cannabis for veterans with PTSD, emphasizing that ignoring cannabis as therapy would be at the “peril” of servicemen and women.
With veterans experiencing disproportionately high rates of PTSD, in some cases up to 34% more than the general population, Shulkin believes that studying the potential therapeutic benefits of cannabis is essential to improving their mental health outcomes.
In all, the evidence suggests that cannabis is not a direct cause of suicidal ideation, particularly in individuals with PTSD. In fact, what we’ve uncovered is quite the opposite, with research showing that cannabis may actually reduce depressive episodes and suicidal thoughts for those suffering from this condition.
As with any discussion on mental health, it’s crucial to take a nuanced approach considering the multiple factors playing a role. So, rather than simplifying the issue, we need more balanced and thorough research to debunk the myths surrounding cannabis and suicide, while exploring its potential therapeutic benefits for those in need.
