First off, candy's main ingredient is sugar and other sweet-tasting substances, which are carbohydrates. We detect these using G protein receptors in our taste buds which send a pleasure signal to our brains, hence why you associate it with happiness. On another note, recent research has shown that sugar is actually addictive and can potentially be a drug.
Personally, I only have sugar to regulate my blood levels.
