A subtle improvement is observed when GLCM texture metrics were added to Sentinel-1 data

The aim of this paper is to 1)conduct a comparative analysis of the SMILE Google Earth Engine machine learning classifiers and analyze their performance in crop type classification over a semi-arid irrigated heterogeneous landscape; 2) classify cannabis fields in the Bekaa region for the years 2016, 2017 and 2018 using multi-temporal multispectral imagery and GEE […]

Pairwise comparisons assessed whether response categories of each sociodemographic characteristic  differed significantly from one another

Multivariate modeling indicated that adolescents with a history of cannabis use had lower perceived risk of harm compared with those who had a history of using other substances. This is an important finding as studies have found that cannabis consumption decreases perceived risk of harm from using cannabis . Limitations to consider when interpreting results […]

Cannabis  users younger than 18 years of age have a 1 in 6 chance of developing cannabis dependence

Approximately one-third of people with epilepsy will experience treatment-resistance which is defined as failure of adequatetrials of two tolerated, appropriately chosen antiepileptic drugs to achieve seizure-freedom.Children unresponsive to conventional treatments face an increased risk of cognitive, behavioral,and psychosocial dysfunction that can have a negative impact on their health and development . This prognosis has led to strong consumer interest in […]

The use of other illicit drugs was associated with a lower severity of diminished expression after 12-months

A developing brain subject to chronic cannabis-exposure may to a greater extent affect these underlying mechanisms, and hence result in increased severity of diminished expression. Apathy, on the other hand, is linked to reward expectancy and cost-benefit-computation . It is possible that these mechanisms have other determinants, and therefore present as associations to male sex […]

We used the Breslow method to handle ties in the timing of reported outcome events

Brief individual interventions addressing substance use motivations and expectancies have been successful in reducing adolescent cannabis use ; however, research on preventing initiation through brief intervention and among JIY is nascent. Extension of expectancies research with JIY samples is necessary, particularly using prospective data and examining the role of positive expectancies and cannabis use outside […]

Research suggests combustible smoking or vaping cannabis is associated with respiratory-related symptoms and disease

This study underscores the importance of studying in-home cannabis smoking, which occurs at a higher rate than in-home tobacco smoking; however, more research is needed. Cannabis users comprise a sizeable population, both in absolute and relative terms, and with cannabis laws becoming more liberal, the number of users is rising. A major public health goal […]

Tobacco has also been found to be a partial driver of cannabis dependence in young people who use tobacco and cannabis

The non-linear  effect of age of first tobacco use on average HONC score can be described as a slight decrease until age 8, followed by a slight increase between 8 and 12 years, and then a sharp decrease with age. Hazardous substance use in adolescence can increase risk for substance use disorders in adulthood, which […]

The classical multivariate regression is a standard method for modeling multiple outcomes jointly

More recently, a simple cumulative risk index was developed to classify which adolescents are at risk for developing persistent substance disorders in adulthood using risk factors from childhood and adolescence . Another recent study built a model for predicting quantitative risk of developing cannabis use disorder in adults based on personal risk factors using statistical […]

Multiple pathways are possible and the influences may vary by developmental stage

In the past year, 25% of EA ages 18–24 have initiated/increased cannabis use in response to negative stress and emotions – the steepest rise in use across all queried age groups; further, 43% of EA reported past year cannabis use, the highest rate observed in 35 years . While the literature supports important links between […]

Multiple pathways are possible and the influences may vary by developmental stage

Even EA who share experiences of inequality or similar challenges in emotion regulation may not experience similar outcomes some will experience stable or worsening problems while others will transition towards resilience and recovery. In some contexts, such as for individuals in high subjective and objective inequality contexts, differences in emotion regulation and the associated underlying […]
