this is sold at smoke shops legally,
I've done my fair share of shrooms but this is seriously trippy , I did it a few days ago
the high lasts for about 5 mins and you really do feel like you've left this realm

I definately had a level 5 experience and can safely say I wil never do that again
Level One — "Subtle" effects of Salvia in small doses
Perception that "something" is happening, with no explanation
Relaxation
Meditative feelings and heightened sexual sensations
Level Two — "Altered" perception
Enhanced colors and textures
Changed space and depth perception
Dream-like experience, "eye candy" hallucinations with closed eyes
Awareness of distinction between fleeting visual effects and reality
Level Three — "Light" visionary state
Clear images with fractal and geometric patterns with eyes closed
Two-dimensional imagery with eyes closed
Vague images or dream-like "eye candy" hallucinations, without confusion with reality
Level Four — "Vivid" reaction
Impression of a complete, dream-like state of alternate reality with eyes closed
Complex, three-dimensional images with eyes closed
Hearing of voices
Knowledge of reality with eyes open
"Shaman" level; journeys to foreign lands, encounters with spiritual beings, feelings of becoming another person
Level Five — "Immaterial" existence with consciousness severely affected
Lack of individuality; universal consciousness merges with other objects, real or imagined
Lucid thought processes; movement coupled with confusion
Extreme pleasure or fear felt by the experimenter
"Sitter" level; need for someone else present who watches and ensures an injury-free, reassuring experience for the disoriented person
Absence of reality; wrapped in an inner experience
Level Six — "Amnesic (amnesia-like effects)" — the most extreme
Loss of consciousness; no memory of experience afterwards
Falling down; thrashing about
No perception or recollection of pain or newly acquired injuries
Deep trance-like state not often sought, since no memory remains after the experience
No recollection and loss of all control, thus discouraged by most sources
