Check out trackerschool.com, or pick up any one of Tom Brown, Jr's books on Tracking, Nature Awareness, Wilderness Survival, etc. Tom was raised by a Native American who taught him many of the old ways, which Tom now teaches at his school. I've been to some of his classes and they are amazing. I would recommend The Tracker, The Vision, The Quest, or Awakening Spirits to start.
Nothing druggie about that kind of shaminism, just living close to the earth and having respect for all living things.
