31. Safety of Psilocybin in Clinical Setting

"Our investigations provided no cause for concern that administration of PY [psilocybin] to healthy subjects is hazardous with respect to somatic health. However, as our data revealed tendencies of PY to temporarily increase blood pressure, we advise subjects suffering from cardiovascular conditions, especially untreated hypertension, to abstain from using PY or PY-containing mushrooms. Furthermore, our results indicate that PY-induced ASC [altered states of consciousness] are generally well tolerated and integrated by healthy subjects. However, a controlled clinical setting is needful, since also mentally stable personalities may, following ingestion of higher doses of PY, transiently experience anxiety as a consequence of loosening of ego-boundaries."

32. Medicinal Potential of Psilocybin

"Today, the medical value of hallucinogens is again being examined in formal psychiatric settings. One substance under investigation is psilocybin, 4-phosphoryloxy-N,N-dimethyltryptamine, which occurs in nature in various species of mushrooms. Psilocybin is rapidly metabolized to psilocin, which is a potent agonist at serotonin 5-HT1A/2A/2C receptors, with 5-HT2A receptor activation directly correlated with human hallucinogenic activity.16 Psilocybin was studied during the 1960s to establish its psychopharmacological profile; it was found to be active orally at around 10 mg, with stronger effects at higher doses, and to have a 4- to 6-hour duration of experience. Psychological effects were similar to those of lysergic acid diethylamide (LSD), with psilocybin considered to be more strongly visual, less emotionally intense, more euphoric, and with fewer panic reactions and less chance of paranoia than LSD."17,18

33. Psilocybin and Treatment of End-Stage Cancer Anxiety

"Despite the limitations, this study demonstrates that the careful and controlled use of psilocybin may provide an alternative model for the treatment of conditions that are often minimally responsive to conventional therapies, including the profound existential anxiety and despair that often accompany advanced-stage cancers. A recent review from the psilocybin research group at Johns Hopkins University describes the critical components necessary for ensuring subject safety in hallucinogen research.36 Taking into account these essential provisions for optimizing safety as well as adhering to strict ethical standards of conduct for treatment facilitators, the results provided herein indicate the safety and promise of continued investigations into the range of medical effects of hallucinogenic compounds such as psilocybin."

34. Description of Salvia Divinorum

"Salvia divinorum is a perennial herb in the mint family native to certain areas of the Sierra Mazateca region of Oaxaca, Mexico. The plant, which can grow to over three feet in height, has large green leaves, hollow square stems and white flowers with purple calyces, can also be grown successfully outside of this region. Salvia divinorum has been used by the Mazatec Indians for its ritual divination and healing. The active constituent of Salvia divinorum has been identified as salvinorin A. Currently, neither Salvia divinorum nor any of its constituents, including salvinorin A, are controlled under the federal Controlled Substances Act (CSA)."

35. Description of Salvia and Its Effects

"Salvia divinorum is a psychoactive plant that can induce dissociative effects and is a potent producer of visual and other hallucinatory experiences. By mass, salvinorin A, the psychoactive substance in the plant, appears to be the most potent naturally occurring hallucinogen. Its native habitat is the cloud forests in Mexico. It has been consumed for hundreds of years by local Mazatec shamans, who use it to facilitate visionary states of consciousness during spiritual healing sessions.57 It is also used in traditional medicine at lower doses as a diuretic to treat ailments including diarrhoea, anaemia, headaches and rheumatism. Effects include various psychedelic experiences, including past memories (e.g. revisiting places from childhood memory), merging with objects and overlapping realities (such as the perception of being in several locations at the same time).58 In contrast to other drugs, its use often prompts dysphoria, i.e. feelings of sadness and depression, as well as fear. In addition, it may prompt a decreased heart rate, slurred speech, lack of coordination and possibly loss of consciousness.59"
