A 130 pound person would have to eat 25 pounds of chocolate to get a marijuana-like effect.

Chocolate also contains phenylethylamine (related to amphetamines) that cause blood-sugar to rise, causes blood pressure to rise, and quickens the pulse. These effects are also found when someone is in love (phenylethylamine is called the "love-drug").
