i hope you are aware that our human brains have receptors for cannabinoids.

again, you can always vaporize, eat, drink, or rub it in. im not saying its great for everyone, or that you MUST use it; however, there are proven benefits from use and it is one of the least harmful things in existence. you cant overdose on it, and there is no physical addiction.

cannabis has a laundry list of positive effects.

Neurogenesis:

http://www.jci.org/articles/view/25509

from abstract, "We show that both embryonic and adult rat hippocampal NS/PCs are immunoreactive for CB1 cannabinoid receptors, indicating that cannabinoids could act on CB1 receptors to regulate neurogenesis. This hypothesis is supported by further findings that HU210 promotes proliferation, but not differentiation, of cultured embryonic hippocampal NS/PCs likely via a sequential activation of CB1 receptors, Gi/o proteins, and ERK signaling. Chronic, but not acute, HU210 treatment promoted neurogenesis in the hippocampal dentate gyrus of adult rats and exerted anxiolytic- and antidepressant-like effects."
