Researchers gave 10 adults placebo cigarettes and three active marijuana cigarettes (including a 3.58% Delta9-THC dose) in a repeated-measures lab test. Using a task that forced a choice between a risky and a nonrisky option, the highest THC dose made people choose the risky option more often. The same high…
Researchers followed two groups of people who planned to use a psychedelic. They gave questionnaires before the trip, then about two weeks and four weeks after. On average, people reported less avoidance of painful thoughts and feelings, lower depression scores, and less thinking about suicide after using a psychedelic. The…
This questionnaire study (2016–2017) compared a representative Czech sample (n = 1800, mean age 46.6, 48.7% male) and a clinical sample of patients with anxiety or adjustment disorder (n = 67, mean age 40.5, 18.0% male). People who reported childhood emotional abuse, emotional neglect, or physical neglect had higher odds…
The authors reviewed 73 mass shooting events (75 shooters) from the Mother Jones database to look for signs of autism spectrum disorder (ASD). They found tentative evidence of ASD in 6 of 75 shooters (8%), plus 16 other cases with some indication; the 8% figure is called a conservative estimate…
This study tested whether anger and aggressive actions are linked differently for men and women. Four hundred twenty-four adults did a behavioral aggression task, and 304 of them also answered questions about their typical anger. Men and women showed similar amounts of aggression overall. However, higher trait anger predicted more…
This study followed 4,285 U.S. children from the Adolescent Brain Cognitive Development Study to look at patterns of addictive use of social media, mobile phones, and video games from about ages 11 to 15. The researchers found that high or steadily increasing patterns of addictive use were common. Those high…
Researchers followed 402 inner-city women who had experienced childhood abuse. They looked at PTSD symptoms, two protective self-views (self-esteem and self-efficacy), and later resource loss. The study found that childhood abuse was linked to more PTSD symptoms and more resource loss later on. Higher PTSD symptoms were tied to lower…
This large South Korean study followed 3,951,398 adults for an average of 11.1 years to compare deaths in people with and without recorded mental disorders. After adjusting for age, sex, health conditions, income, smoking, drinking and physical activity, people with mental disorders had higher rates of suicide and higher overall…
This review looks at studies on using classic psychedelics and nutraceuticals to treat concussion and lasting symptoms after mild traumatic brain injury. Concussion is common in the military, civilians, and contact sport players and usually causes temporary mental impairment, though a small minority have lasting problems. The authors report that…
This study looked at 111 children aged 7–12 who came to a pediatric emergency department with suicidal thoughts or behaviors. It found that emotional dysregulation (trouble managing strong feelings) helped explain the link between an anxious attachment style toward parents and actual suicidal behaviors. The study did not find the…
This paper looks at a technology called self-nanoemulsifying drug delivery systems, or SNEDDS. SNEDDS are oil-based mixes that turn into very tiny droplets when they meet the fluids in the gut. The paper explains how these tiny droplets can help drugs that do not dissolve well in water get into…
The researchers compared betrayal sensitivity (and, secondarily, shame and self-criticism) in four groups of women: 34 IPV survivors who were single, 25 IPV survivors who were dissatisfied with a relationship, 32 IPV survivors who were satisfied with a relationship, and 42 women with no IPV history. They found that all…
