Volatile Substance Misuse: Toward a Research Agenda.
ABSTRACT Background: Volatile substance misuse (VSM) is a significant but under-researched global health problem. Objectives: This perspective calls for additional VSM research in key areas including the phenomenology and adverse health and social consequences of acute inhalant intoxication and for prospective longitudinal studies of the natural history of VSM and related deleterious long-term biomedical and psychosocial outcomes. Taxonomic investigations are needed to identify subtypes of volatile substance misusers (VSMs), whereas qualitative and mixed methods evaluations would provide important information about cultural and interpersonal contexts and specific patterns, modalities and agents of VSM. Treatment outcome and health services studies have rarely been conducted with reference to VSMs and are needed. Studies of specific inhalants and high-risk populations for VSM would also contribute to current knowledge regarding VSM and help reduce the toll taken by this prevalent form of drug misuse. Methods: The authors draw on VSM studies that they and other researchers have conducted to exemplify the types of research needed in each of the domains identified above. Results and Conclusions: Despite the global ubiquity of VSM, much remains to be learned about this form of substance use. This perspective identifies key elements of a systematic program for research in this area.

ABSTRACT: The psychedelic experience has been reported since antiquity, but there is relatively little known about the underlying neural mechanisms. A recent neuroimaging study on psilocybin revealed a pattern of decreased cerebral blood flow and functional disconnections that is surprisingly similar to that caused by various anesthetics. In this article, the authors review historical examples of psychedelic experiences induced by general anesthetics and then contrast the mechanisms by which these two drug classes generate altered states of consciousness.Anesthesiology 09/2013; DOI:10.1097/01.anes.0000435635.42332.ee · 6.17 Impact Factor

ABSTRACT: Inhalatomania with volatile organic compounds is a still present phenomenon among Polish young adolescents. Conscious, voluntary exposition on such substances may result in serious health consequences, including sudden death in the course of acute intoxication. In this paper, atypical case of death of 16-year-old teenager as a result of complications of physically forced inhalation of gas for lighters is presented. According to testimonies of witnesses, the container was placed in the mouth of victim and the gas was introduced directly to his throat. Autopsy revealed small damage of tooth with corresponding bruising of lower lip; brain and lung oedma; single bruisings in the upper respiratory tract and subpleural. Chemical-toxicological analysis of blood, brain and lung samples taken during autopsy revealed in all of them the presence of n-butan--a component of gas for lighters (the greatest in brain and lung tissues). Additionally, in blood the presence of carboxyhemoglobin (COHb) in concentration 7% was confirmed. Based on the results of analyses, acute intoxication with n-butan was estimated as a cause of death; however the key role played the information obtained during the investigation. This case shows, that deaths resulting from gas for lighters inhalation may be a consequence of forced exposition--against victim's will. So medical staff should always check, if on the body of patient there are any signs of physical constraint (the presence of bruisings in the area of viscerocranium and oral cavity, teeth damages, etc.).Przegla̧d lekarski 01/2013; 70(7):473-5.
