Short term effects of cannabinoids like CBD as anti depressants are clear. You can take that to the bank.

CBD directly activates the 5-HT1A (hydroxytryptamine) serotonin receptor, thereby conferring an anti-anxiety effect

What even better is the longer term effects of cannabinoids on the CAUSE for the environment that creates depression, both inside and outside a patient body. For example, lack of sleep will be a co factor both inside the body and outside the body that accentuate depression.
