Background Integration — the ongoing process of revisiting, making sense of, and incorporating the content of a psychedelic experience into daily life — is a core component of psychedelic-assisted therapy (PAT), but is variably operationalised and poorly reported in clinical research. Objective To map how integration is described, delivered, and reported in clinical studies of classic...
Despite high-dose 3,4-methylenedioxymethamphetamine (MDMA) drug alerts being distributed, no research has been conducted as to changes in use in response. This study aimed to determine if: (i) high-dose MDMA drug alerts, and (ii) varied descriptions of dose, effects and actions to reduce harm were associated with intentions to reduce the initial MDMA dose in a hypothetical scenario. Australians...
While the potential of serotonergic psychedelics and related substances as adjuncts in substance-assisted psychotherapy (SAPT) has been investigated for the treatment of several disorders, evidence for the appropriate therapeutic conduct in administration sessions is sparse. In this article, we discuss the current evidence for best therapeutic practice during administration sessions with...
BACKGROUND: Clinical trials are currently investigating the potential of substance-assisted psychotherapy (SAPT) as treatment for several psychiatric conditions. The potential therapeutic effects of SAPT may be influenced by contextual factors including preparation prior to and integration after the substance-assisted therapy sessions. AIMS: This systematized review outlines recommendations for...
Colorimetric reagent kits can provide information about the compounds present in drug samples. This study aimed to identify patterns and correlates of colorimetric reagent kit use, as well as behavioural outcomes of testing, amongst people who use illegal stimulants in a context that lacks permanent government-sanctioned drug checking services. Australians residing in capital cities who...
This study aimed to determine design features of a drug-checking service that would be feasible, attractive and likely to be used by Australian festival and nightlife attendees. Web survey of 851 Australians reporting use of psychostimulants and/or hallucinogens and attendance at licensed venues past midnight and/or festivals in the past year (70% male; median age 23 years). A drug-checking...
The purpose of this article is to debate current understandings about the psychobiological effects of recreational 3,4-methylenedioxymethamphetamine (MDMA or 'ecstasy'), and recommend theoretically-driven topics for future research. Recent empirical findings, especially those from novel topic areas were reviewed. Potential causes for the high variance often found in group findings were also...
Examine the motivations for new psychoactive substance (NPS) use amongst a sample of regular psychostimulant users (RPU) in Australia, and determine whether motivations differ across substances. Data were obtained from 419 RPU interviewed for the 2014 Ecstasy and related Drugs Reporting System who reported lifetime NPS use. Based on the most recent NPS used, motivations for use were rated on an...
Over the past decade, monitoring systems have identified the rapid emergence of new psychoactive substances (NPS). While the use of many NPS is minimal and transitory, little is known about which products have potential for capturing the attention of significant proportions of the drug consuming market. The aim of this study was to explore self-reported experiences of three commonly used NPS...
The aim of the study was to investigate the relationship between chronic cannabis use and visual selective attention by examining event-related potentials (ERPs) during the performance of a flanker go/nogo task. Male participants were 15 chronic cannabis users (minimum two years use, at least once per week) and 15 drug naive controls. Cannabis users showed longer reaction times compared to...
New Psychoactive Substances are now a feature of Australia's recreational drug market. Little is known, however, about the prevalence of use, the characteristics of people who use them and the relationship between the NPS and ecstasy markets. This study examined the prevalence and correlates of NPS use amongst a group of regular ecstasy users in Australia. Participants were recruited if they...
The past decade has seen the development of an array of emerging psychoactive substances (EPS), however, there is minimal information on the extent of their use outside Europe. This study aimed to determine the extent of use of EPS from stimulant (such as mephedrone) and psychedelic classes (such as 5-methoxy-dimethyltryptamine [5-MeO-DMT]) among an Australian sample of regular ecstasy users...
‘Ecstasy’ (3,4‐methylenedioxymethamphetamine) induces impaired functioning in the serotonergic system, including the occipital lobe. This study employed the ‘tilt aftereffect’ paradigm to operationalise the function of orientation‐selective neurons among ecstasy consumers and controls as a means of investigating the role of reduced serotonin on visual orientation processing. The magnitude of...
Although use of 'ecstasy' (drugs sold as containing 3,4-methylenedioxymethamphetamine) is prevalent, it is typically infrequent, and treatment presentations involving ecstasy as a principal problem drug are relatively rare. Human case reports and animal literature suggest dependence potential, although there may be some unique aspects to this syndrome for ecstasy in comparison to other...
A growing body of evidence suggests that regular 'ecstasy' (3,4-methylenedioxymethamphetamine) use causes lasting changes to central serotonergic functioning in humans, including in the occipital lobe. Serotonin may play a role in visual orientation processing, mediated in the occipital lobe, via lateral inhibition. The tilt aftereffect is an illusion apparent following adaptation to stimuli...
