Wow, I just noticed that this thread has been read over 1000 times! I find that rather impressive.

Now, you want to drop a moose or a moosehead, try smoking a bowl of pure Perique! For those of you who don't know, Perique is a special type of tobacco used in blending to add flavor. It is grown in only a small triangle of land in Louisiana in a bayou. The nutrients in the swampy land impart a strength to the tobacco not found elsewhere in the US despite being the same species. After it is harvested the Perique is compacted into barrels and buried in the swamp where it is allowed to fermet in its own juices.

Perique is some seriously powerful stuff. Usually blenders use only a pinch of it to add flavor to several pounds of other tobaccos! Added in extremely small quantities it adds an almost plumlike flavor and a strength to the aroma. Alone it gives off a horrible stench, I guess it's trying to mimic the odor of the swamp life decomposing, and it makes your mouth feel like it's full of swamp crude.

The turn of the century occultist Alistair Crowley used to smoke pure Perique soaked in rum in his pipes, and that has actually been suggested by scientists as the source of his hallucinations! The fermenting process can give pure Perique, in sufficient quantities, the ability to induce hallucinations and more.
