The use of d-amphetamine pellet implantation as a model for d-amphetamine tolerance in the mouse [PDF]

open access: yesPsychopharmacologia, 1973
The use of d-amphetamine pellet implantation as a method for producing rapid central drug tolerance was investigated. Mice were implanted with d-amphetamine pellets containing 2 mg of drug and were challenged 24 h later, a time when no detectable drug was present, with various doses of d-amphetamine i.p.
