Cannabis Use and Mental Health Problems

This paper investigates whether cannabis use leads to worse mental health. To do so, we account for common unobserved factors affecting mental health and cannabis consumption by modeling mental health jointly with the dynamics of cannabis use. Our main finding is that using cannabis increases the likelihood of mental health problems, with current use having a larger effect than past use. The estimates suggest a dose response relationship between the frequency of recent cannabis use and the probability of currently experiencing a mental health problem.cannabis use;mental health;duration models;discrete factor models

The Effects of Cannabis Use on Physical and Mental Health

This paper investigates whether cannabis use aects physical and mental health. To do so, information on prime aged individuals living in Amsterdam in 1994 is used. Dutch data offer a clear advantage in estimating the health impacts of cannabis use because the legal status of cannabis in the Netherlands ensures that estimates are free from confounding with the physical and psychological effects of engaging in a criminal activity. Accounting for selection into cannabis use and shared frailties in mental and physical health, the results suggest that cannabis use reduces the mental wellbeing of men and women and the physical wellbeing of men. Although statistically significant, the magnitude of the effect of using cannabis on mental and physical health is found to be small.cannabis use;physical health;mental health;duration models

Why Parents Worry: Initiation into Cannabis use by Youth and their Educational Attainment

In this paper we use individual level data from the Australian National Drug Strategy Household Survey to study the relationship between initiation into cannabis use and educational attainment. Using instrumental variable estimation and bivariate duration analysis we find that those initiating into cannabis use early in life are much more likely to dropout of school compared to those who start later on. Moreover, we find that the reduction in years of schooling depends on the age at which initiation occurs, and that it is larger for females than males.cannabis use;age of initiation;educational attainment

Why Do Some People Want to Legalize Cannabis Use?

Preferences and attitudes to illicit drug policy held by individuals are likely to be an important in uence in the development of illicit drug policy. Amongst the key factors impacting on an individuals preferences over substance use policy are their beliefs about the costs and benefits of drug use, their own drug use history, and the extent of drug use amongst their peers. We use data from the Australian National Drug Strategy's Household Surveys to study these preferences. We find that current use and past use of cannabis are a major determinants of being in favor of legalization. We also find that cannabis users are more in favor of legalization the longer they have used cannabis and, among past users, the more recent their own drug using experience. This may be re ecting the fact that experience with cannabis provides information about the costs and benefits of using this substance. We also find some evidence that peers use of cannabis impacts on preferences towards legalization.cannabis use;drugs policy

Translating Patient-Oriented Eczema Measure (POEM) scores into clinical practice by suggesting severity strata derived using anchor-based methods

Background: The Patient-Oriented Eczema Measure (POEM) is a validated, patient-derived assessment measure for monitoring atopic eczema severity, although further information on how different POEM scores translate into disease severity categories is needed for clinical trials, epidemiological research and audit. Objectives: We sought to determine the relationship between Patient-Oriented Eczema Measure (POEM) scores (range 0–28) and two Global Questions (GQ1 and 2) concerning patients’/parents’ views of the overall severity of their/their child’s atopic eczema, in order to stratify POEM scores into five severity bands. Methods: POEM scores and GQs were completed by 300 patients from general practice and 700 patients from dermatology outpatient clinics, including 300 adults aged ≥ 16 years and 700 children. Results: The mean POEM score was 136 (range 0–28), and standard deviation (SD) was 72. Mean GQ1/GQ2 scores were 21/21, respectively (range 0–4 and SD 11 for both). The mean, mode and median of the GQ scores for each POEM score were used to devise possible POEM bandings. The proposed banding for POEM scores are: 0–2 (clear/almost clear); 3–7 (mild); 8–16 (moderate); 17–24 (severe); 25–28 (very severe), kappa coefficient 046. Conclusions: Severity banding of the POEM will allow more clinically meaningful use in everyday clinical practice and as a core outcome measure in future atopic eczema research
