ya i'm having trouble getting a good result. I've been using the color system (green, yellow, red, and purple) i worked my way through them and got to purple, but i still am not getting anything close to the crazy effects people talk about. I'm using a bong, and a butane torch, and i'm holding it in for 30 seconds, i can't figure it out. Is it possible to build up a resistance to salvia? cus if it is i might have done that from doing so much red prior to the purple. how long should i wait to lose the resistance??
