You know, I've been interested in astral projection and meditation for a long time as well. I've never succeeded at it no matter what techniques I use lol. However, once I started smoking cannabis, I did have one random OBE, where I went nowhere and just held onto my body and pulled myself back in quickly. Also, I did post a guide to meditation with cannabis in these forums not too long ago. You should check it out if interested. (http://boards.cannabis.com/showthread.php?t=68743)
