Objective: Cannabis use has increased in the United States, particularly the use of vaporized cannabis oil, which is often mixed with thinning agents for use in vaporizing devices. E-cigarette research shows that heated thinning agents produce potentially harmful carbonyls; however, similar studies have not been conducted (1) with agents that are commonly used in the cannabis industry and (2) at temperatures that are appropriate for cannabis oil vaporization. The goal of this study was to determine whether thinning agents used in the cannabis industry produce potentially harmful carbonyls when heated to a temperature that is appropriate for cannabis oil vaporization.

Many advances have been made toward understanding the benefits of medical cannabis. However, less is known about medical cannabis patients themselves. Prior research has uncovered many important patient characteristics, but most of that work has been conducted with participants in California, who may not represent medical cannabis patients throughout the United States.

Considerable work has shown the benefits for psychological health of being gender typed (i.e., perceiving oneself in ways that are consistent with one's sex).

We addressed several issues concerning children who show gender non-normative (GNN) patterns of peer play. First, do young children with GNN peer preferences differ from children with gender normative (GN) peer preferences in problem behaviors? Second, do GNN and GN children differ in sociability and isolation and do they have differential socialization opportunities with externalizing, internalizing, and socially competent peers? We employed a Bayesian approach for classifying children as GNN based on their peer preferences as compared to their peers using a sample of Head Start preschool children from a large Southwestern city (N = 257; 53 % boys; M age = 51 months; 66 % Mexican American). To calculate socialization opportunities, we assessed affiliation to each child in the class and weighted that by each peer's characteristics to determine the exposure that each child had to different kinds of peers.

Controversy surrounds questions regarding the influence of being gender consistent (i.e., having and expressing gendered characteristics that are consistent with one's biological sex) versus being gender flexible (i.

The relations between young children's mutual (reciprocated) and overall positive emotion (PE) with same- and other-gender peers and their social adjustment were explored. Children's PE and peers' PE were observed across the preschool year during peer interactions (N = 166; 46% girls; M age = 52 months). Results revealed that girls and boys had similar frequencies of overall PE and mutual PE when interacting with same-gender peers, but girls were marginally higher compared with boys in overall and mutual PE when interacting with other-gender peers.

The benefits versus costs of gender typing are not clear: Is adjustment optimal when people identify and act in strongly gendered ways or when they embrace characteristics of both sexes? Previous findings are inconsistent, in part because they are derived from different conceptualizations of gender typing. A comprehensive understanding of the mental health consequences of gender typing requires recognition of the multidimensionality of gender typing and simultaneous consideration of these dimensions. On the basis of previous work on individual measures, we hypothesized that adjustment would be differentially associated with different aspects of gender typing: positively with sex-congruent gender identity and male-typed personality traits, negatively with rigid gender attitudes, and minimally with female-typed personality traits and gender-typed activity interests.
