Abstract
Harnessed rhesus monkeys, surgically prepared with indwelling jugular catheters, were given access by means of remotely controlled infusion pumps to unlimited quantities of delta-9-trans-tetrahydrocannabinol. Naive monkeys as well as monkeys which were automatically infused with THC for over 28 days did not self-administer THC. Monkeys which had a history of multiple drug self-administration also did not self-infuse THC.
