“A Final Pathway for Reducing Anxiety”: If Smoking Cannabis ‘Stresses’ You Out, This Might Be Why

Northwestern University scientists have identified a set of brain neurons that contribute to increased feelings of stress and anxiety after consuming cannabis, especially if the psychoactive cannabis consumption is paired with a stressful situation. The study found that cannabis consumption weakened the brain’s natural "brake" on the somatostatin neurons in the amygdala, a region associated with fear and stress processing. The research team also noted that this effect was amplified when the cannabis was consumed alongside a stressful environment. The findings suggest that cannabis may have different effects depending on the circumstances, such as when it is paired with a stressful situation.

The study involved laboratory mice that were either given a synthetic cannabinoid drug or a placebo and exposed to a threatening odor derived from fox urine. Drugged mice froze more often and spent less time investigating the odor than the placebo group. The researchers monitored brain activity using implanted microscopes and found that cannabis consumption reduced the brain's natural brake on somatostatin neurons, which are involved in regulating anxiety. The team's findings indicate that the combination of cannabis and stress can lead to heightened anxiety levels.

The implications of the study are significant, as it provides scientific support for anecdotal claims that cannabis can both reduce and amplify stress depending on the context. The research suggests that understanding how cannabis affects brain function could lead to new ways of managing anxiety, particularly in situations where cannabis is used alongside stressful environments. The study also highlights the potential for cannabis to have a dual effect on anxiety, which could inform future research and treatment strategies for anxiety disorders.
