I must be getting old, but this old hippie long ago lost his taste for different dimensions. Here's one I hadn't heard of: salvia divinorum
Salvia divinorum is a bright, leafy green plant from Mexico that when chewed or smoked causes intense hallucinations comparable to LSD or "magic mushrooms."
And it's legal in California.
The drug is available all over the Bay Area, mostly in smoke shops and herbal stores. It's also sold over the Internet. For $15 to $50 a hit, users get a high that sends them into a dream-like state for anywhere from a few minutes to an hour or two.
Unlike well-known illicit drugs such as marijuana or cocaine, salvia is not in widespread use. It hasn't caught the attention of state or local health departments. San Francisco police said that while they're aware of salvia, it's not yet a problem.
Here's a picture:
Here's some history from Wikipedia:
Salvia divinorum originates from the region of Oaxaca in Mexico where it is still used by the Mazatec Indians, primarily to facilitate shamanic visions in the context of curing or divination, but also remedially at lower doses to treat ailments including diarrhea, anemia, headaches, rheumatism, and a semi-magical disease known as panzon de borrego, or a swollen belly.[10] It was first recorded in print by Jean Basset Johnson in 1939 as he was studying Mazatec shamanism.[11] He later documented its usage and reported its effects through personal testimonials.[12] It was not until the 1990s that the psychoactive mechanism was identified by a team led by Daniel Siebert.[13]
The history of the plant is not known, but there are three possibilities as to its origin. Since it is found in one small area and only one indigenous group uses it, it is either native to this area, is a cultigen of the Mazatecs, or is a cultigen of another indigenous group.[6] Wasson theorized that this plant was the mythological pipilzintzintli, the "Noble Prince" of the Aztec codices.[3] However, this theory is not without dispute.
So now you know. Go now at your own risk.
