Hawaiian Baby Woodrose, or HBW, is a climbing vine known by the botanical name Argyreia Nervosa. It is encountered in the Carribean, Africa, and areas of Hawaii. It bears small seeds which look very much like small chocolate chips. The seeds are often collected and consumed for the psychedelic alkaloids they contain.
Currently, HBW is not a controlled substance in the US, however the LSA they contain is listed as a schedule III controlled substance.
User reports on HBW seeds suggest that not many seeds are required for an effect. Psychedelic effects become apparent with 4 or more seeds eaten on an empty stomach.
LSA is believed to act similarly to most classical hallucinogens; It is likely to exhibit agonist and/or partial agonist activity at multiple serotonin receptors, including the 5HT-2A subtype.
The effects of LSA are similar to the effects of LSD, and are reported to be less intense. The experience typically lasts 6 to 8 hours, though a pleasant afterglow may linger for up to 12 hours.
Psychological effects of LSA include Introspection, Altered cognitive process, Laughing or an urge to laugh, Closed or open eye visual distortions such as spots, light tracers, color shifting, distortion of surface textures, brightened or enhanced colors, Enhancement of sensory input such as taste, smell, sound, or vision, and Time distortion. Physiological effects include Dilated pupils (mydriasis), Increased heart rate, CNS stimulation or sedation, Insomnia, Stomach pain or cramps, and Mild to severe nausea and vomiting (some reccommend taking a regular dose of dimenhydrinate or diphenhydramine 30 minutes before consuming the seeds).
Likely After-Effects include Possible "hangover" characterized by blurred vision with vertigo or dizziness, and an ability to acheive a deep or refreshing sleep following the experience.
