The authors assessed 23 subjects immediately before and six months (27.5 weeks) after their first ayahuasca experience in an urban Brazilian religious setting, either Santo Daime (N = 15) or União do Vegetal (N = 8). Measures included scores on instruments assessing psychiatric symptoms, personality variables and quality of life. Independent variables were the frequency of ayahuasca use...
Salvia divinorum is a naturally occurring psychedelic considered to be one of the most potent hallucinogens found to date. The few behavioral studies conducted conclude that Salvia's effects may be similar to traditional psychedelics, which is noteworthy because Salvia acts via a unique molecular mechanism as a kappa opioid receptor agonist. One hundred and ninety-three participants, including...
This study assesses the availability of websites offering to sell psilocybin spores and psilocybin, a powerful hallucinogen contained in Psilocybe mushrooms. Over a 25-month period beginning in March 2003, eight searches were conducted in Google using the term "psilocybin spores." In each search the first 100 nonsponsored links obtained were scored by two independent raters according to...
Ayahuasca, a hallucinogenic plant brew from the Amazon basin used as part of healing ceremonies by the local indigenous people of the region for centuries, is now being consumed by growing numbers of people throughout the world. Anecdotal evidence and previous research suggest that there are spiritual effects experienced among participants who take part in ayahuasca ceremonies. The current...
Many ancient cultures and religions engaged in various techniques and used various substances to instigate religious experience and to alter perception. These techniques of psycho-sexual drug yoga reached an unparalleled level of sophistication that arose and was often cloaked in practical terms of alchemy and metallurgy. The Vedic tradition describes this plant-based ritualism as soma, which...
Ecstasy use remains a key concern for professionals working in fields related to youth and drug use. At the forefront of these concerns are issues related to neurological dysfunction and depression--both acute and long-term--associated with MDMA use. Ecstasy users have been shown to assess Ecstasy related harms and to engage in a variety of practices to manage these risks. To contend with risk...
The purpose of this study was to investigate the safety of different doses of MDMA-assisted psychotherapy administered in a psychotherapeutic setting to women with chronic PTSD secondary to a sexual assault, and also to obtain preliminary data regarding efficacy. Although this study was originally planned to include 29 subjects, political pressures led to the closing of the study before it...
Recent attention to the monoamine oxidase inhibiting properties of Banisteriopsis caapi's harmala alkaloids has precluded a balanced assessment of B. caapi's overall significance to indigenous South American societies. Relatively little attention has been paid to the cultural contexts, local meanings and patterns of use of B. caapi among snuff-using societies, such as the Piaroa, who do not...

Legal prohibitions on this plant native to Oaxaca, Mexico have emerged at the state level, a phenomenon that has not occurred since the passage of the Controlled Substances Act (CSA). Included will be a brief description of the plant that has only recently crept into the popular American consciousness, and...
In 2006, the Supreme Court paved the way for the sacramental use of a hallucinogen, hoasca, to be imported, distributed and ingested by a religious group. This case has broad implications for religious freedom for using sacramental psychotropics and how such cases might be decided in the future. This article outlines the arguments used both by the church and by the government. It lists the...
Human interest in psychoactive phenethylamines is known from the use of mescaline-containing cacti and designer drugs such as Ecstasy. From the alkaloid composition of cacti we hypothesized that substances resembling Ecstasy might occur naturally. In this article we show that lophophine, homopiperonylamine and lobivine are new minor constituents of two cactus species, Lophophora williamsii...

Nonetheless, controversy remains about the causal nature of the association. This review takes the debate further through a critical appraisal of the evidence. An electronic search was performed, allowing to identify 622 studies published until June 1st 2005....
A prior study found that one ketamine-assisted psychotherapy session was significantly more effective than active placebo in promoting abstinence (Krupitsky et al. 2002). In this study of the efficacy of single versus repeated sessions of ketamine-assisted psychotherapy in promoting abstinence in people with heroin dependence, 59 detoxified inpatients with heroin dependence received a...
Due to potential serotonergic deficits, 3,4-methylenedioxymethamphetamine (MDMA or Ecstasy) may cause long-term mood disruptions in recreational Ecstasy users. The purpose of this review is to evaluate the evidence for a relationship between recreational Ecstasy use and higher levels of depressive symptoms. Eleven out of 22 studies initially have reported significantly higher depression scores...
Although spirituality is an integral component of some of the most popular approaches to substance abuse treatment, there is little empirical evidence for a causal relationship between spirituality and treatment success. In the present study, 169 (121 male) opiate- or cocaine-abusing treatment seekers completed the Index of Spiritual Experience (INSPIRIT), a questionnaire that assesses both...
The increase in recreational use of ketamine in France led to the carrying out of a survey aimed at depicting the sociological profiles of French ketamine users, their addictive behaviors, and the characteristics relevant to the use of the substance. This survey is based upon the analysis of 250 questionnaires, 24 semi-directive interviews, and two focus groups. Data was collected between July...
Ketamine is a dissociative anesthetic that has emerged as an increasingly popular choice among young drug users. Recent research indicates the presence of hidden populations of young people who inject ketamine in New York and other U.S. cities. Applying an ethno-epidemiological approach, the authors recruited 40 young injection drug users (IDUs) (< 25 years old) in New York City to explore...
This is an article in two parts. The first part discusses current research in psychoactive preparations of ergot in various religious systems with a particular emphasis on Persian, Greek, Jewish and Islamic sources. Certain poems, hadith, and scriptural writings suggest an entheogenic heritage to various ancient sects that exerted and received philosophical and ritual influences over large...
The present study deals with two ethnobotanical surveys carried out in two different segments of the Brazilian population: the first among the Krahô Indians living in Tocantins State, a Cerrado region, and the second one among the descendants of former black slaves, the Quilombolas, living in Mato Grosso State. Both populations use plants which may have effects on the central nervous system...
This research explored whether hypnotic suggestion could produce a subjective mindbody condition similar to that produced by the psychoactive drug methylenedioxy methamphetamine (MDMA, Ecstasy). Twelve participants received posthypnotic instructions to re-experience an MDMA-like state posthypnotically, similar to one in their prior experience, for one hour. Three separate self report measures...
Psychedelic drugs such as LSD and psilocybin are often claimed to be capable of inducing life-changing experiences described as mystical or transcendental, especially if high doses are taken. The present study examined possible enduring effects of such experiences by comparing users of psychedelic drugs (n = 88), users of nonpsychedelic illegal drugs (e.g., marijuana, amphetamines) (n = 29) and...
The term "date rape drug" has traditionally been applied by the media to powerful sedatives, such as gamma hydroxybutyrate (GHB) and flunitrazepam (Rohypnol), which can render a person unconscious and hence unable to resist and/or recall an assault. However, some law enforcement agents and others have recently obtained convictions by arguing that the empathy-generating and sensual effects of...
The use of Ecstasy in Brazil has gained visibility in recent years. Nevertheless, scientific data on this issue remain scarce. The present study focused on clarifying this phenomenon by means of qualitative and ethnographic research. Observational studies (N = 8), information obtained from key informants (N = 14) and interviews with Ecstasy users (N = 32) from the city of São Paulo were part of...
