Warning Signs of Drug Abuse


Warning Signs of Drug Abuse

Drugs are the most important medical tool used by mankind since time immemorial. A drug is any chemical substance which alters the physiology or behavior of an organism either directly or indirectly. Drugs are broadly distinguished from substances and food that offer only dietary support. In addition, a drug can be a chemical substance, a biological agent, or a formulation (a mixture of two or more substances).

Almost every human being has been exposed to drugs at some point of his/her life. Some countries have a high rate of death due to drugs accidents as compared to other countries with low death rates. The rate of drug overdose has also increased steadily, and hence the number of drug users has also increased steadily. Hence drugs are a great threat to the mankind. As a result, drug abuse and addiction have created many problems for the society.

In fact, it is estimated that drug users will account for one fifth of the population of any country in the next five years. Various drugs are used as stimulants, depressants, pain relievers, anti-anxiety pills, and antibiotics. Although illegal drugs are mainly used for their effects, but they can cause negative health consequences when not used properly. For example, cocaine, crack, heroin, methamphetamine, and barbiturates can cause heart attacks, strokes, and lung cancer. Therefore, if an individual uses these drugs on a long term basis, he/she will become physically and mentally weaker as time goes by and eventually, he/she will become addicted to them and may become helpless.

Pharmaceutical Industry

The pharmaceutical industry finds, develops, manufactures, and sells pharmaceuticals or biological drugs to the public for the purpose to heal them, diagnose them, treat them, or relieve the symptoms of their diseases. Pharmaceutical firms can also deal in biotechnological and generic drugs and other medical devices. They carry out the process of development of new drugs by interacting with the various stakeholders such as the academic community, the industry, government and users’ groups to derive the ideas and concepts that are essential to produce new medicines. Other pharmaceutical companies produce chemical agents and regulate the production of pharmaceutical products.


A major portion of the pharmaceutical budget is used for research and development of useful medicines and drugs. The pharma industries provide a large number of jobs to thousands of graduates and post-graduate professionals who opt for specialization in various sectors such as biotechnology and nutrition. Many pharmaceutical graduates choose a career in pharmaceutical marketing and management, in clinical research, in government and public health, in healthcare management, in pharmacology and in marketing of drugs. There are huge requirements for pharmacists in both the private and public sector. There are many career options in pharmaceutical engineering.

Technological advances have allowed the production of medicines that are stronger than those found in the past. In addition, the introduction of new molecular structures has led to the production of drugs that are more potent and that have better absorption and excretion characteristics. Some of the common medicines that are produced in laboratories are antibiotics, antiviral, chemotherapy drugs, cholesterol management drugs, hormones, blood pressure, depression drugs, diabetes, birth control pills, sex hormones, oral contraceptives, vitamins, orthopedics and vision care drugs. Several generic versions of these drugs are also manufactured. The cost of producing a generic drug is lower than the cost of producing a patented drug.
