People most often use serotonergic psychedelics (hallucinogens) to expand their awareness, such as to increase self-knowledge, promote spiritual development, or satisfy curiosity. This motive appeared in 78% of the 37 studies reviewed, followed by coping (67%) and enhancement (57%). The pattern held across different types of psychedelics, different cultural backgrounds, and both quantitative and qualitative research, with no significant changes from 1967 to 2020. To reduce potential harms, harm-reduction services might offer non-drug ways to fulfill the desire for expanded awareness. Future research should examine motives for specific psychedelics.

About 5.3% of respondents in a large international survey reported using binaural beats to experience altered states, with higher rates in the United States, Mexico, Brazil, Poland, Romania, and the United Kingdom. Younger age and non-male gender predicted use, as did recent use of cannabis, psychedelics, and novel drugs. Most users listened to relax or fall asleep (72.2%) or change their mood (34.7%), while 11.7% sought effects similar to those of other drugs—a motivation more common among classic psychedelic users (16.5% vs. 7.9%). Users primarily accessed binaural beats via video streaming sites on mobile phones.

Ibogaine, a psychoactive alkaloid from the Tabernanthe iboga plant traditionally used in Bwiti culture, has been used experimentally to treat substance use disorders (SUD) since 1962. Interviews with 13 people who self-treated their SUD with ibogaine revealed that the drug's therapeutic benefits arise not only from its pharmacology but also from the subjective experience it induces. Participants reported that ibogaine evoked interpersonal and transpersonal experiences, autobiographical memories, and personal insights. These effects, along with preparation, integration, and motivation for lifestyle change, appear to help individuals cope with their SUD, particularly given limited alternative treatment options.

Chronic nitrous oxide use inactivates vitamin B12, causing neurological and psychiatric damage. A case series from an Australian emergency department between 2019 and 2021 identified 22 patients, mostly young males (median age 22.4 years), who inhaled a median of 150 bulbs daily for 9 months. Common symptoms included ataxia, numbness, falls, urinary retention, and psychosis; 12 of 14 patients who underwent MRI had spinal cord degeneration. All received vitamin B12 injections, and many also oral methionine. Hospital stays lasted a median of 4 days, costing about $2,061 per day. The data prompted public health measures such as warning labels, purchase limits, and legal restrictions on sales intended for abuse.

Among adults entering randomly selected electronic dance music events in New York City, the proportion who had tested their ecstasy with a drug testing kit in the past year rose from 23.1% in 2017 to 43.1% in 2022, an 86.6% increase. Among those who tested, the share who always tested their drug rose from 31.2% to 60.6%. The proportion who found out or suspected their ecstasy was adulterated fell from 59.6% to 18.4%, with suspected methamphetamine adulteration dropping from 21.9% to 3.6%. The findings indicate growing use of drug testing kits and decreasing suspected adulteration, supporting the need for formal drug checking services.

Among people who attend electronic dance music parties in New York City, experiencing a harmful or very unpleasant effect after using cocaine or ecstasy in the past month was associated with a lower willingness to use the same drug again in the next month. For cocaine, the adjusted prevalence ratio was 0.58, and for ecstasy, 0.45. Adverse effects from LSD or ketamine did not show a statistically significant association with willingness to use again after adjusting for other factors. The findings suggest that personally experienced adverse effects can deter future use of some party drugs in this high-risk population, and interventions may benefit from highlighting such effects.

At three Australian music festivals in 2022/2023, blood samples from 24 critically ill patrons revealed that unreported illicit drugs or new psychoactive substances were detected in 18 patients. Among these, methylamphetamine was found in 10 patients, cathinones in 7, and benzodiazepine-type new psychoactive substances in 6. The most frequently reported and detected drugs were MDMA, ketamine, and cocaine. The toxicosurveillance network provides additional intelligence for harm reduction, aiming to identify high-risk drug use patterns and inform evidence-based messaging.

GHB withdrawal can be far more prolonged than the typical 5-7 days, sometimes recurring over 56 days despite initial stabilization and toxicological evidence of abstinence. A male patient in his 30s with a 15-year history of daily high-dose GHB use experienced three hospital admissions over 8 weeks, each requiring intravenous sedation and intubation for agitated delirium. His withdrawal delirium was successfully treated with a slow, six-month taper of benzodiazepines and baclofen, preventing further re-emergence of the debilitating delirium. This case demonstrates that severe GHB withdrawal may require extended support and slow medication tapering, with benzodiazepines and GABA-B agonists as effective treatments.

Receiving a high-dose MDMA drug alert was associated with intentions to reduce or avoid the drug in a hypothetical scenario. In an online survey of Australians who had used MDMA pills or capsules in the past year, 45.4% of those shown an alert said they would not use the drug, compared to 20.7% of the control group. Among alert recipients, 46.7% said they would use and reduce their initial dose, versus 69.0% in the control group. Those who received an alert were about three times more likely to report intending not to use rather than taking a smaller dose, compared to the control group. Different phrasings of the alert did not significantly change intended behavior.

Drug alerts in Australia are triggered when MDMA pills contain at least 150 mg of free-base MDMA, a threshold experts consider reasonable despite its limitations. Nineteen such alerts were issued in 2024, raising concerns about diminishing impact. Fifteen experts who design and disseminate drug alerts completed a survey, and seven participated in a focus group. Most agreed 150 mg is a reasonable threshold because it enables rapid communication and addresses potential harm, though thresholds cannot account for evolving manufacturing or consumption trends. Limited capacity to monitor community perceptions means there is little evidence to justify changing the threshold. Notifying communities about high-dose MDMA remains a harm-reduction priority; improving monitoring and establishing a dosage database could enhance future risk communication.

From 2021 to 2023, Australians who regularly used ecstasy or other stimulants and also used nitrous oxide showed a rise in use of large cylinders (from 6% to 26%) and a rise in reported neurological symptoms (from 5% to 14%). Most respondents knew about brain or nerve damage risks, but only one in five identified vitamin B12 depletion as a risk, and 17% were unaware of any risks. One-third took no precautions. Sourcing from convenience stores and 24/7 delivery services was common and linked to heavier use. Fewer than five people received treatment for symptoms. The authors call for balanced regulation and education of retailers, clinicians, and consumers.
