Make sure you have a scale to measure out an accurate dose, don't eye it. I'd start off with roughly 15-20 milligrams. At those doses it is easily handled and controllable. I'd just find a nice place to do it, with a couple of close friends.
^^i agree with deadhead, you need to make sure your doses are accurate. It's very easy to take too much of an RC especially since most of them are active at such low dosages. Make sure you have a clear head, or are at least calm and have a good mental state of mind before tripping. Other than that, enjoy. -DP
