An example of a drug interaction in the brain and body of humans would be sugar.
Sugar works in a complex way. Foods are rated on a glycemic index. Food items containing sugar that break down in your body and enter the blood steam quicker have a higher index number. The slower it enters the blood stream, the lower the index value.
When you eat a food that has a high glycemic index value, a lot of sugar is entering your blood stream fast. You start to feel a sugar "high". You brain notices this and your body starts releasing insulin to lower the sugar level in your bloodstream storing it for energy. Then it lowers the level low enough to cause you to experience a sugar "crash", thus, making you sluggish and lethargic. This makes your brain tell you that you want more sugary foods. This cycle perpetuates over and over until you stop eating the sugar.
