TL;DR
Short-term memory, reaction time, EEG, and heart rate were significantly affected by the higher dose; time estimation and blood sugar were not differentially affected by either dose.
Abstract
The effect of high and low doses of marijuana on behavioral and physiological responses was studied in male medical school volunteers. Short-term memory, reaction time, EEG, and heart rate were significantly affected by the higher dose; time estimation and blood sugar were not differentially affected by either dose.

The 11-hydroxy metabolites of Delta(8).- and Delta(9)-tetrahydrocannabinol are more active than the parent compounds when administered to mice by either the intravenous or intracerebral route.

The mechanisms by which marihuana alters mental functions are not likely to be answered in man, nor even answered soon by animal studies, so it may be necessary to look to additional animal studies to provide leads for pertinent future studies in man.

High oral doses of marihuana extract significantly impaired the serial coordination of cognitive operations during a task that required sequential adjustments in reaching a goal and disintegration of sequential thought was related to impaired immediate memory.

A number of performance tests proved insensitive to marihuana in the doses used and effects on complex reaction time and on digit code memory tasks were impaired, but there were marked individual differences.
