Trip Magazine seems to have run its course in the print environment:
“There are just a few more of issue 10 left, the VERY LAST issue of Trip Magazine! Order your signed collector’s copy today! Featuring Afro Celts, The Bad Shaman, Drug Geeks, Erik Davis, and more!”
There have actually been some pretty enlightening articles posted on the web site, including a first person account of tryptamine hallucinations, so you might want to check it out.
