Cannabis & Dysthymia (Persistent Low Mood)
Two-way link: Cannabis can worsen ongoing low mood, and low mood can drive heavier use.
False relief: Short-term calm gives way to long-term dullness, fatigue, and lack of motivation.
Research shows: Regular cannabis users—especially those who started young—report higher depressive symptoms and slower recovery.
Better options: Exercise, breathwork, nutrition, quality sleep, and therapy all improve dopamine and serotonin naturally without dulling motivation.
The adolescent and young adult brain is still undergoing major structural and functional changes: synaptic pruning, myelination, maturation of the prefrontal cortex (which governs executive function, impulse control, planning) and development of neural circuits linking emotion, reward, memory.
The brain’s endocannabinoid system (which cannabis acts upon) plays a role in neural development, connectome refining, and regulation of stress, reward and emotion. Interfering with this during a sensitive period may have downstream consequences.
According to the Centers for Disease Control and Prevention (CDC), “the teen brain is actively developing and continues to develop until around age 25. Cannabis use during adolescence and young adulthood may harm the developing brain.”
