Artemisia absinthium is a perennial plant. It grows to a height of approximately one to three feet. It flowers from summer to early fall. This plant is more commonly called wormwood. The most famous beverage made from wormwood is Absinthe. Absinthe is a highly alcoholic, distilled spirit that contains wormwood as a primary ingredient. An elaborate ritual surrounds the traditional serving of absinthe. water and sugar are mixed with absinthe to mask its flavor. The absinthe is poured into the glass first. special glasses with a small bubble in the bottom are traditionally used to help the pourer measure the amount of absinthe to be poured. Absinthe is poured until it reaches the top of the bubble. A specially slotted spoon, often resembling a pie server, is placed on the top of the glass. a single sugar cube is placed on the spoon. water is then poured over the sugar cube, through the slotted spoon. Everything is mixed together. There are psychoactive chemicals in absinthe called Thujones. There are many sources for wormwood. Here are some:

This information came from a book called "Legally Stoned" by Todd A. Thies

I highly recommend this book because it has a list of 14 mind altering substances that can be obtained without breaking the law. It is a great resource filled with information and dosages and much more.
