ABSTRACT
Cannabis is the most widely used illicit drug in many western countries. Its
psychoactive ingredient, delta9-tetrahydrocannabinol (THC), produces a variety
of effects in animals and humans that are probably mediated by specific
cannabinoid receptors in the brain and interactions with several
neurotransmitter and neuromodulator systems. For instance, recent research has
revealed an important mutual functional relationship between cannabinoids and
endogenous opioid systems in mediating the pharmacological and behavioral
actions produced by these agents, including their reinforcing effects. Perinatal
exposure to and interactions between cannabinoids and opioids might also have
long-term behavioral consequences lasting into adulthood. In this work, we
present preliminary evidence examining the potential effects of maternal
exposure to THC on the motivational properties of morphine in male and female
adult rats, as measured by an intravenous opiate self-administration paradigm.
