Powerful. One hit of dry herb off a vaping pen, and within seconds, it hit the frontal lobe. That one hit lasted, more than four hours, strongly. I was immediately relaxed and let the tingling in my forehead rock me with my pulse. For my shell-shock depression/PTSD, it gives you the best feelings of an Indica dominant hybrid and yet, you get a fantastic buzz, an active buzz. I never felt sleepy.
