Drugs are chemicals that make changes to the structure of the human body and can only react chemically as it is the only action which drugs are competent. Due to the chemical structures of different drugs can affect the human body in various ways, however, few drugs make necessary changes that is, if a person needs an insulin for diabetes or chemotherapy for cancer. Most of the harmful drugs directly or indirectly target the reward system of the brain by tormenting the circuit with dopa mine which is a neurotransmitter present in regions of the brain that regulate movement, emotion, cognition, motivation, and feelings of pleasure.
Drugs can affect the brain
Few of the experiments done on animals have shown that certain drugs like ecstasy can damage brain cells, but experts do not agree on whether such thing happens with humans. By in taking a wide range of drugs such as ecstasy, LSD and solvents, there have been chances about damage to the brain. However, undue and long term use of alcohol can also lead to possible brain damage.
Drugs can affect the heart
Heavy drinking of alcohol and regularly consuming of tobacco may lead to a greater risk of heart problems. Consuming alcohol on a regular basis may result in weakening the ability of the heart to pump blood, which might cause heart failure. Similarly, nicotine which is found in tobacco is a kind of stimulant which increases the workload of the heart and at the same time carbon monoxide takes away the oxygen of the heart which is needed.
Drugs can affect liver and lungs
Gradually neutralizing the affects of the drug, the liver alters the chemical structure of the drugs and slowly but surely stops working. Drugs such as ecstasy and drinking of alcohol constantly can impairment the liver of a human body.
Thus while using drugs, many possible risks and dangers might rise and can even cause side effects. For an instant, a person whose stimulants are high may experience an augment in energy which is caused by intake of drugs may speed up the metabolism of the body and the heart rate. Hence intake of excessive drugs can risk ones health and over a long period, taking drugs on regular basis might slowly lose its result.

Drugs can affect the brain
When drugs get into the bloodstream, it concedes to all parts of the body and few particles reach the brain which can affect the brain functionality. As brain is known as the master control center of the body, it sends messages to the rest of the body based on the signals that it gets from the drugs. The most easiest and dangerous way of getting drugs into the brain is to inject it intravenously or injecting it into the vein.

Drugs can affect the heart
Drugs can also have a consequence on the heart directly and aggravate heart disease. The drugs that are taken enter the bloodstream and the heart pumps blood containing the drug to the brain where it affects the human body. Taking customary and high doses of tonic drugs like amphetamine, cocaine/crack, ecstasy, anabolic steroids and even possibly caffeine may increase the risk of heart attacks, especially for people who are already suffering from heart problems or high blood pressure.
Heavy drinking of alcohol and regularly consuming of tobacco may lead to a greater risk of heart problems. Consuming alcohol on a regular basis may result in weakening the ability of the heart to pump blood, which might cause heart failure. Similarly, nicotine which is found in tobacco is a kind of stimulant which increases the workload of the heart and at the same time carbon monoxide takes away the oxygen of the heart which is needed.
Drugs can affect liver and lungs
Most of the drugs can cause damage to the liver and lungs of a human body, which will make the body powerless to fight off infection. Lungs which are one of the most important organs of a human body, helps inhaling oxygen directly and very effectively to the body, however anything that is inhaled will enter the blood and very quickly to the brain. Drugs such as solvents and poppers/nitrites can also be inhaled, whereas, drugs like solvents are directly absorbed into the lungs.
Gradually neutralizing the affects of the drug, the liver alters the chemical structure of the drugs and slowly but surely stops working. Drugs such as ecstasy and drinking of alcohol constantly can impairment the liver of a human body.
