Psychosis is one of the most serious among the adverse effects associated with cannabis use. The association between cannabis use and psychosis has been variously explored in a series of recent meta-analyses. The results of these meta-analyses show that persons who develop psychosis experience onset of psychosis about 2-3 years earlier if they are cannabis users; this effect is not observed with alcohol or other substance use. Higher levels of cannabis use are associated with greater risk of psychosis. Current cannabis abuse or dependence (but not past use or lower levels of current use) increases the risk of transition into psychosis in persons at ultrahigh risk of psychosis...

Recent epidemiological data indicate an increasing trend in the nonmedical use of prescription drugs among college students. The nonmedical use of prescription drugs involves using a prescription medication without a prescription, or using the medication in a manner inconsistent with a health care provider's instructions. Among college students, prescription stimulants have the highest ratio of nonmedical to medical use and the highest rate of illicit selling and trading on college campuses. The increased prevalence is accompanied by increased risk, as 18-25-year-olds have the highest rate of emergency department visits for nonmedical use of prescription stimulants (NMUPS)...

IMPORTANCE: With rising rates of marijuana use in the general population and an increasing number of states legalizing recreational marijuana use and authorizing medical marijuana programs, there are renewed clinical and policy concerns regarding the mental health effects of cannabis use. OBJECTIVE: To examine prospective associations between cannabis use and risk of mental health and substance use disorders in the general adult population. DESIGN, SETTING, AND PARTICIPANTS: A nationally representative sample of US adults aged 18 years or older was interviewed 3 years apart in the National Epidemiologic Survey on Alcohol and Related Conditions (wave 1, 2001-2002; wave 2, 2004-2005)...

Besides the common illicit drugs, such as cocaine, heroin, and marijuana, there is a growing concern about the use of modern "designer drugs" that have emerged in large numbers over the past few years. In this work, a sensitive and selective method for simultaneous determination of 25 synthetic amphetamine-like psychoactive compounds, including amphetamine, sympathomimetic substituted amphetamines, synthetic cathinones and ketamine, in raw wastewater (RW), secondary effluent (SE) and river water was developed...

Marijuana policy is rapidly evolving in the United States and elsewhere, with cannabis sales fully legalized and regulated in some jurisdictions and use of the drug for medicinal purposes permitted in many others. Amidst this political change, patients and families are increasingly asking whether cannabis and its derivatives may have therapeutic utility for a number of conditions, including developmental and behavioral disorders in children and adolescents. This review examines the epidemiology of cannabis use among children and adolescents, including those with developmental and behavioral diagnoses...

This technical report updates the 2004 American Academy of Pediatrics technical report on the legalization of marijuana. Current epidemiology of marijuana use is presented, as are definitions and biology of marijuana compounds, side effects of marijuana use, and effects of use on adolescent brain development. Issues concerning medical marijuana specifically are also addressed. Concerning legalization of marijuana, 4 different approaches in the United States are discussed: legalization of marijuana solely for medical purposes, decriminalization of recreational use of marijuana, legalization of recreational use of marijuana, and criminal prosecution of recreational (and medical) use of marijuana...

Acute marijuana use is classically associated with snacking behavior (colloquially referred to as "the munchies"). In support of these acute appetite-enhancing effects, several authorities report that marijuana may increase body mass index in patients suffering from human immunodeficiency virus and cancer. However, for these medical conditions, while appetite may be stimulated, some studies indicate that weight gain is not always clinically meaningful. In addition, in a study of cancer patients in which weight gain did occur, it was less than the comparator drug (megestrol)...

INTRODUCTION: A medical visit for plant ingestion is rare in the pediatric emergency services but may involve a high toxicity. The botanical toxicology training of health staff is often very limited, and it can be difficult to make a diagnosis or decide on the appropriate treatment. OBJECTIVE: To study the epidemiological and clinical characteristics of poisoning due to plant ingestion in order to increase the knowledge of the health professional. MATERIAL AND METHODS: A descriptive retrospective study was conducted on patients seen in a pediatric emergency department after the ingestion of plant substances from January 2008 to December 2012...

PURPOSE OF REVIEW: Substance use may persist throughout the life course and has a substantial impact on health outcomes globally. As HIV-infected individuals are disproportionately impacted by substance use and living longer, it is critical that providers and researchers alike understand the impact of substance use on older, HIV-infected patients and potential treatment options. To this end, we conducted a review of the literature focusing on the most commonly used substances to outline the epidemiology, health consequences, treatment options and latest research relevant to older, HIV-infected patients...

Medical marijuana remains a highly debated treatment regimen despite removal of state penalties against care providers prescribing the drug and patients treated with the drug in many areas of the USA. The utility of marijuana in specific medical conditions has been studied at length, but its effects on driving performance and risk of motor vehicle collision remain unclear. As with other medications that affect psychomotor function, the healthcare provider should be informed of the potential risks of driver safety prior to prescribing this psychotropic drug to give appropriate anticipatory guidance for appropriate use...

Sexual revictimization (experiencing 2 or more rapes) is prevalent and associated with increased risk for posttraumatic stress disorder (PTSD) and substance use. However, no national epidemiologic studies have established the prevalence or relative odds of a range of types of substance use as a function of sexual victimization history and PTSD status. Using three national female samples, the current study examined associations between sexual revictimization, PTSD, and past-year substance use. Participants were 1763 adolescent girls, 2000 college women, and 3001 household-residing women...

On August 30, 2013, the Colorado Department of Public Health and Environment (CDPHE) was notified by several hospitals of an increase in the number of patients visiting their emergency departments (EDs) with altered mental status after using synthetic marijuana. Synthetic marijuana is dried plant material sprayed with various synthetic cannabinoids and smoked as an alternative to smoking marijuana. In response to the increase in ED visits associated with the use of synthetic marijuana, CDPHE asked all Colorado EDs to report through EMResource (a web-based reporting system) any patients examined on or after August 21 with altered mental status after use of a synthetic marijuana product...
