Conditional probabilities of substance use disorders and associated risk factors: Progression from first use to use disorder on alcohol, cannabis, stimulants, sedatives and opioids. Drug and alcohol dependence, 194, 136-142.

Highlights

Pre-existing mental disorders increases the risk of developing SUD.

  • Prior SUD increases the risk of transitioning from use to use disorder.
  • Highest rates of transition to SUD occurred among stimulant and opioid users.
  • Mood and anxiety disorders increased the risk of transitioning to AUD and CUD.
  • The rapidity of transition to SUD emphasizes the narrow opportunity to intervene.

Abstract

Background

Relatively little is known about factors that may lead to the development of a substance use disorder (SUD), across a range of drug classes. This study aimed to identify...

Abstract

Cannabis use is observationally associated with an increased risk of schizophrenia, but whether the relationship is causal is not known. Using a genetic approach, we took 10 independent genetic variants previously identified to associate with cannabis use in 32 330 individuals to determine the nature of the association between cannabis use and risk of schizophrenia. Genetic variants were employed as instruments to recapitulate a randomized controlled trial involving two groups (cannabis users vs nonusers) to estimate the causal effect of cannabis use on risk of schizophrenia in 34...

Triggering Myocardial Infarction by Marijuana

Jose Luis Vazquez Martinez -

In 2001, Murray Mittleman and other researchers published the article 'Triggering Myocardial Infarction by Marijuana.' They interviewed 3,882 patients with acute myocardial infarction, on average four days after infarction onset. They used the case-crossover study design to compare the reported use of marijuana within 60 minutes preceding symptoms of myocardial infarction onset to its expected frequency using self-matched control data. The results show that in the studied population, the risk of myocardial infarction onset was elevated 4.8 times over baseline in the first hour after marijuana...

The effect of alcohol, THC and their combination on perceived effects, willingness to drive and performance of driving and non-driving tasks. Accident Analysis & Prevention, 42(6), 1855-1865.

It has been suggested that cannabis use increases risk of driving collisions through affecting braking and choice reaction time; causing impairment of lane position, disrupting head-way and dynamic tracking; distorting time perception; reducing divided and sustained attention; and increasing caution. 

A recent Canadian study, published just two days before cannabis was legalized across the country, investigated the impact of cannabis use on driving performance in young recreational users.

The study investigated 45 recreational marijuana users between the ages of 18 and 24. Participant’s...
