I first started noticing the rush of my chi when i would be high. All it is is just relaxing the muscles to make that energy free flowing. If your looking for a good practice to study, Qigong is a perfect one. All smoking does it increase the flow more easily, and being able to control it or activate it at any time, well for me at least. All the techniques and practices have similar results..activating the chi everyday for complete mind clarity and body-mind connection. I just started meditating about 2 months ago but i am already making good progress. my hands get real hot and allow me to heal my aching body parts( which are easy to see when your high cause your so relaxed) by focusing on the breath sucking out the bad as you exhale, well thats just how i picture it, we all have different ways of imaginative guidence of our chi. I highly recommend the Qigong Basics book found at local librarys, its very helpful in your understanding of your body and the power of your mind intent. ( its all about your mind intent, im just now realizing the gravity of that statement) how i helped, but the most important thing is meditate and focus on your breathing and releasing of your chi through your breathing
