Different drugs can affect the body in different ways, but all drugs chemically alter the brain.  The drug effects that occur in people who do drugs depend on how the brain processes the  chemicals in each drug. The amount of drugs needed to cause certain effects vary as well.  What a person feels, hears, smells, tastes, thinks, and sees depends on what the brain is  saying to the person's body. The brain and body have normal functioning patterns and  operate according to very specific patterns when a person does not consume substances that  cause any type of chemical disruption. However, when chemicals are introduced to the brain,  the chemical messengers in the brain are changed, causing the brain to send a different set of  signals to the body. Chemicals can cause people to see, think, and act very differently than  they normally would, which is why drug abuse affects people and the world around them.    

When alcohol enters the bloodstream, it causes a wide range of effects across many different  ​
bodily systems. The effects begin as soon as the alcohol gets into your blood. However, the  speed at which alcohol enters the bloodstream depends on a few factors. Carbonated  alcoholic drinks, such as champagne, enter the bloodstream faster than non­carbonated  drinks. When you have a full stomach, alcohol is absorbed more slowly than when you have  not eaten in a while. Once alcohol is in your bloodstream, your breathing and heart rate slow  down and you experience feelings of drowsiness, mental confusion, and intoxication. The
