Answer:
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. They also tend to have the same effects, in varying amounts.
There are three typical classifications of drugs. These include Hallcinogens, Uppers, and Downers. Hallicongoens include heroine. These drugs give their users and experience that they could never have without them. As their name suggest, they hallucinate. They see images, stories, and even mental videos as if they were actually happening. Uppers exicte a person. These are the drugs that make you feel like you can do anything. They give you a false sense of energy. Downers include marjauna, and alcohol. The effect of these are a feeling of calm, and peacefulness.
With those descriptions drugs might sound enticing. However, they have many negative effects. These include heart disease, heart attacks, the progression of cancers, weight loss, weight gain, unproductivness, and uncontrollale behaivor. All of the effects that I just mentioned will keep one from being able to play sports. You can run a relay when your heart is failing because of drugs, or alcohol. An idea to keep away from drugs is to find freinds who are also drug, and alcohol free.
