Abstract
The purpose of this experiment was to test the hypothesis that chronic marijuana usage changes the percentage of time in various sleep wakefulness periods in cats. Marijuana was administered daily for 180 days to six cats. Base line predrug sleep wakefulness periods were established for each cat, and the cats were also observed for a 40 day postdrug period. A decrease in slow wave sleep and an increase in drowsy light sleep occurred during the 180 day drug period and continued through the 40 day postdrug period. Although there were changes in both REM sleep and awake time during the drug period, these changes did not persist during the 40 day postdrug period.
