Study Suggests: Cannabis Successfully Treats Depression

Research has suggested that cannabis may be a promising treatment option for a number of different physical and mental health conditions, from post-traumatic stress disorder to chronic pain. A study released in *2014 suggests that depression can be added to that list.
Neuroscientists from the University of Buffalo’s Research Institute on Addictions found that endocannabinoids — chemical compounds in the brain that activate the same receptors as THC, an active compound in marijuana — may be helpful in treating depression that results from chronic stress.
In studies on rats, the researchers found that chronic stress reduced the production of endocannabinoids, which affect our cognition, emotion and behavior, and have been linked to reduced feelings of pain and anxiety, increases in appetite and overall feelings of well-being. The body naturally produces these compounds, which are similar to the chemicals in cannabis.

Reduction of endocannabinoid production may be one reason that chronic stress is a major risk factor in the development of depression.
Then, the research team administered marijuana cannabinoids to the rats, finding it to be an effective way to restore endocannabinoid levels in their brains — possibly, thereby, alleviating some symptoms of depression.
“Using compounds derived from cannabis — marijuana — to restore normal endocannabinoid function could potentially help stabilize moods and ease depression,” lead researcher Dr. Samir Haj-Dahmane said in a university press release.
Recent research around marijuana’s effect on symptoms of post-traumatic stress disorder further bolsters the Buffalo neuroscientists’ findings, since both disorders involve the way the brain responds to stress. A study published last year in the journal Neuropsychopharmacology, for instance, found synthetic cannabinoids triggered changes in brain centers associated with traumatic memories in rats, preventing some of the behavioral and physiological symptoms of PTSD.

However, it’s important to note that the relationship between marijuana and depression is complex. Some research has suggested that regular and heavy marijuana smokers are at a higher risk for depression, although a causal link between cannabis use and depression has not been established.
More studies are needed in order to determine whether, and how, marijuana might be used in a clinical context for patients with depression.

  • Seems I remember in my youth that cannabis was unpredictable, I was never sure if it would help me shake a depression, or make it worse. Throughout my teens and twenties I would suddenly fall into a depression with no idea when I would come out of it, it could be days or it could be months. I was always hopeful that cannabis would lift me out of the depths, but sometimes it would become worse…..

    • I have bipolar disorder, and sometimes my depression is so deep that nothing will break it but time. However, cannabis helps me cope without wanting to die until it does, and that’s exactly what I need. Pills didn’t speed up the end of my depression either, but they definitely caused 7 straight years of suicidal thoughts and feelings constantly, in or out of the depressions. I imagine it works differently for everyone, but it does work and without causing horrible side effects…… should be a legal medical option in Tennessee.
