 Illegal drugs are drugs which have limitations on their ownership or use by a government, and are illegal in certain situations (meaning a person is not allowed to have them). A drug is any chemical that affects the human body or mind when it is swallowed, breathed in, or consumed in another way.  Examples of illegal drugs: Weed Cocaine Tobacco

 Addiction is a condition that results when a person ingests a substance.Users may not be aware that their behavior is out of control and causing problems for themselves and others.(e.g., alcohol, cocaine, nicotine).cocainenicotine

 Caffeine--the drug that gives coffee and cola its kick-- has a number of physiological effects. At the cellular level, caffeine blocks the action of a chemical called phosphodiesterase (PDE). Inside cells, PDE normally breaks down the second chemical messenger cyclic adenosine monophosphate (cAMP).

 Cocaine is one of the highly abused drugs all across the world. Many teenagers are becoming addict of this harmful drug. Most of the people are unaware about the disadvantages of cocaine abuse. This is an area of concern for many countries as their youth is going towards wrong direction. Cocaine can be snorted, injected and smoked. It has direct impact on our brain and central nervous system.

 It effects central nervous system because the drug makes you feel down and you don't know what you are doing.

 Stimulants are a class of drugs that “stimulate” the body’s central nervous system, which includes the brain and spinal cord. They increase the levels of catecholamine's—a family of brain chemicals that includes dopamine. These chemicals are used in the brain processes to signal reward and motivation.

 Addiction has an effect on every individual who is close to the one abusing drugs or alcohol. Families are often the ones who suffer most when a relative is in active addiction. In the early stages the family may begin to blame themselves for what’s going on. They may start to believe they are one of the factors that perpetuate the drug use.
