Intense Sweetness Surpasses Cocaine Reward
Many studies have concluded over and over that given the choice 94% of rats in studies will move toward sugar and saccharin over cocaine and heroin. This study by the National Institutes of Health report that when rats were allowed to choose mutually-exclusively between water sweetened with saccharin–an intense calorie-free sweetener–and intravenous cocaine–a highly addictive and harmful substance–the large majority of animals (94%) preferred the sweet taste of sugar and saccharin. Their findings clearly demonstrate that intense sweetness can surpass cocaine reward, even in drug-sensitized and addicted individuals.
