BACKGROUND AND AIMS: Epidemiological trends show marijuana use in the U.S. to have increased in recent years. Previous research has identified cohort effects as contributing to the rising prevalence, in particular birth cohorts born after 1945. However, given recent policy efforts to regulate marijuana use at the state level, period effects could also play a contributing role. This study aims to examine whether cohort or period effects play a larger role in explaining trends in marijuana use...

This review provides an overview of the changing U.S. epidemiology of cannabis use and associated problems. Adults and adolescents increasingly view cannabis as harmless, and some can use cannabis without harm. However, potential problems include harms from pre-natal exposure and unintentional childhood exposure; decline in educational or occupational functioning after early adolescent use, and in adulthood, impaired driving and vehicle crashes; cannabis use disorders (CUD), cannabis withdrawal, and psychiatric comorbidity...

Namkee G Choi, Diana M DiNitto, Carl Nathan Marti
BACKGROUND AND OBJECTIVE: Given that 29 U.S. states now have laws allowing medical marijuana use, this study examined mental and physical health correlates of medical versus nonmedical marijuana use among three age groups of adults (18-29, 30-49, and 50+). METHODS: Data came from the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions (N = 36,309 respondents aged 18+). Logistic regression models were used to examine age group differences in associations of substance use and mental disorders and health conditions with medical versus nonmedical marijuana use...

Nicholas Pintori, Barbara Loi, Maddalena Mereu
Spice drugs are herbal mixtures sprayed with synthetic cannabinoids designed to mimic the psychoactive ingredient in marijuana [Δ-tetrahydrocannabinol (Δ-THC)] and synthesized by introducing modifications to the chemical structure of parental compounds aiming to circumvent legal regulations. Synthetic cannabinoid use/abuse can be devastating as toxicological effects and adverse reactions cannot be entirely predicted and may vary with the dose, route of administration, individual vulnerability and concomitant intake with other drugs...

Importance: Over the last 25 years, illicit cannabis use and cannabis use disorders have increased among US adults, and 28 states have passed medical marijuana laws (MML). Little is known about MML and adult illicit cannabis use or cannabis use disorders considered over time. Objective: To present national data on state MML and degree of change in the prevalence of cannabis use and disorders. Design, Participants, and Setting: Differences in the degree of change between those living in MML states and other states were examined using 3 cross-sectional US adult surveys: the National Longitudinal Alcohol Epidemiologic Survey (NLAES; 1991-1992), the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC; 2001-2002), and the National Epidemiologic Survey on Alcohol and Related Conditions-III (NESARC-III; 2012-2013)...

BACKGROUND AND AIMS: In the United States, overdose deaths attributed to opioid pain relievers (OPR) have quadrupled since 1999, prompting many states to adopt Prescription Drug Monitoring Programs (PMP). This study aimed to: (1) estimate the relationship of PMP strength with OPR overdose deaths across states and over time; (2) measure what threshold in PMP strength is associated with the greatest reduction in OPR overdose; and (3) assess the relationship of medical marijuana dispensaries with OPR overdose deaths...

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)...

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...
