Felix the Khat: Esquire's High in Hell Article
IMHO, Esquire Magazine is the best-written magazine out there. The have a stable of great writers who do first-person commentary on what it's like. I read this article called High in Hell about khat chewing in Dijbouti. Incredible detail. Incredible tension. Incredible drug.
I started reading it at Suburban Station, and never looked up until my stop. Wow.
