Drugs and alcohol can effect the body in many ways. These include, the slowing of reactions, the speeding up of reactions, and all of the side effects that also come with drugs, and alchol. A common drug is caffine. When caffiene enters the digestive system it takes about 30 mintues to make it's way past it, and into the blood stream. The caffine enters cells and blocks something called adenosine. This is the molocule responsible for making us feel tired. This drug, and many other follow that path.
