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

Issue: 
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.

An Extract of Neem Leaves Reduces Anxiety without Causing Motor Side Effects in an Experimental Model

Issue: 
Pages: 
245–8
Synopsis: 
Anxiety levels were assessed after treatment with either a steroidal extract of neem leaves or diazepam. An animal model of anxiety, the elevated X maze, provided reliable evidence of anxiolysis without motor deficit in neem treated rats.
