Dosage and Conditioning Period Determine Reward or Aversion to Cannabis-induced Conditioned Place Preference in Sprague-Dawley Rats

Issue: 
Vol 66, Issue 5: 2017 (Special Issue on Cannabis)
DOI: 
10.7727/wimj.2017.185
Pages: 
523-8
Synopsis: 
The study demonstrated that a shortened conditioning period of 18 minutes in the conditioned place preference paradigm could induce significant delta-9-tetrahydrocannabinol (∆9-THC) reward at low doses, supporting the addictive potential of the psychoactive agent of marijuana. This is the first report of significant reward at a dose of 0.05 mg/kg of ∆9-THC in an animal model of addiction.

ABSTRACT

Objective: To assess the addictive potential of cannabis by investigating the motivational responses to low doses of delta-9-tetrahydrocannabinol (Δ9-THC) and a marijuana tea extract (MTE), and to determine if the length of the conditioning period in the conditioned place preference (CPP) paradigm influences reward or aversion to these cannabinoid preparations.

The Editor,

Sir,

Following the first description of Cannabinoid Hyperemesis Syndrome (CHS) in 2004, there have been hundreds of cases reported, up to recently. One of the largest series was at the Mayo Clinic (a non-profit organization in the United States of America) where five African-American patients, three Hispanics and 12 patients of ‘Other’ ethnicities were noted in a series of 98 cases of predominantly Caucasian patients (1, 2).

Cannabis Use among Secondary School Students in Jamaica: Factors Associated with Age of Initiation

Issue: 
Vol 66, Issue 5: 2017 (Special Issue on Cannabis)
DOI: 
10.7727/wimj.2017.214
Pages: 
546-52
Synopsis: 
The aim of the study was to determine whether perception of risk and accessibility of cannabis predicted the age of initiation of cannabis among secondary school students in Jamaica. Whereas there was a significant inverse association between grade level in school and age of initiation, perceptions of access did not predict the age of initiation of cannabis.
