Drugs of Abuse

The term “drugs of abuse” lacks a formal medical definition. Historically, discussions of drugs of abuse focused on “street drugs”; however, the adverse effects of the nonmedical use of prescription medications, such as opiates, benzodiazepines, and therapeutic amphetamines, are increasingly seen. The purpose of this review is to aid the clinician in identifying and treating a broad representation of drugs of abuse, which may include those illicitly produced in laboratories (e.g., methamphetamine), diverted pharmaceuticals (oxycodone), and herbal products (marijuana). This review covers stimulants, hallucinogens, cannabinoids, and sedative-hypnotics. Figures show substances ranked according to weighted harm score on a normalized scale from 0 being no harm to 100 being extreme harm to self and others, a treatment algorithm for sympathomimetic toxicity, a treatment algorithm for sedative-hypnotic overdose, and a treatment algorithm for opioid overdose. Tables list commonly abused sympathomimetic agents, modern novel drugs of abuse, commonly abused sedative-hypnotic agents, commonly abused opiates, and pitfalls of the drug screen. This review contains 4 highly rendered figures, 6 tables, and 90 references. Key Words: street drugs, prescription medications, opiates, benzodiazepines, amphetamines, stimulants, hallucinogens, oxycodone, marijuana, overdose

Safety and Efficacy of an On-Site Intensive Treatment Protocol for Mild and Moderate Sympathomimetic Toxicity at Australian Music Festivals

Introduction:Serotonin and sympathomimetic toxicity (SST) after ingestion of amphetamine-based drugs can lead to severe morbidity and death. There have been evaluations of the safety and efficacy of on-site treatment protocols for SST at music festivals.Problem:The study aimed to examine the safety and efficacy of treating patients with SST on-site at a music festival using a protocol adapted from hospital-based treatment of SST.Methods:The study is an audit of presentations with SST over a one-year period. The primary outcome was need for ambulance transport to hospital. The threshold for safety was prospectively defined as less than 10% of patients requiring ambulance transport to hospital.The protocol suggested patients be treated with a combination of benzodiazepines; cold intravenous (IV) fluid; specific therapies (cyproheptadine, chlorpromazine, and clonidine); rapid sequence intubation; and cooling with ice, misted water, and convection techniques.Results:One patient of 13 (7.7%) patients with mild or moderate SST required ambulance transport to hospital. Two of seven further patients with severe SST required transport to hospital.Conclusions:On-site treatment may be a safe, efficacious, and efficient alternative to urgent transport to hospital for patients with mild and moderate SST. The keys to success of the protocol tested included inclusive and clear education of staff at all levels of the organization, robust referral pathways to senior clinical staff, and the rapid delivery of therapies aimed at rapidly lowering body temperature. Further collaborative research is required to define the optimal approach to patients with SST at music festivals.

Methamphetamine Ingestion Misdiagnosed asCentruroides sculpturatusEnvenomation

The authors present a case report of a 17-month-old female child who ingested a large amount of methamphetamine that looked very similar clinically to a scorpion envenomation specific to the southwestern United States by the speciesCentruroides sculpturatus. The child was initially treated with 3 vials of antivenom specific for that scorpion species and showed a transient, though clinically relevant neurologic improvement. Her clinical course of sympathomimetic toxicity resumed and she was treated with intravenous fluids and benzodiazepines after blood analysis showed significant levels of d-methamphetamine. This case report is to specifically underline the clinical confusion in discerning between these two conditions and the realization of limited and/or expensive resources that may be used in the process.
