Project Report from the year 2012 in the subject Sociology - Medicine and Health, grade: A, University of Peshawar (Institute of Social Work, Sociology and Gender Studies), language: English, abstract: Man’s desire to employ substances that provide pleasurable stimulation or narcotic effects upon the central nervous system has been expressed universally in ancient as well as in modern civilization. With the passage of time excessive indulgence in them came to be considering as deprived or criminal behavior. In recent years, however, it has been recognized that drug addiction is a psychiatric and social problem. The very word “drug” means different things for different people. For some people, drugs are those substances which are illegal and socially disapproved of, associated with stereotypes images of “junkies” or solvent snuffers, and not everyday substances that ordinary people use. On other hand many people increasingly refer to all medicinal preparations as drugs. A drug, broadly speaking, is any substance that, when absorbed into the body of a living organism, alters normal bodily function (World Health Organization, 1969). In pharmacology, a drug is "a chemical substance used in the treatment, cure, prevention, or diagnosis of disease or used to otherwise enhance physical or mental well-being (Middle English Drogges, 2007). Addiction is a chronic, often relapsing, brain disease that causes compulsive drug seeking and use, despite harmful consequences to the addicted individual and to those around them. Although the initial decision to take drugs is voluntary for most people, the brain changes that occur over time challenge a person’s self-control and ability to resist intense impulses urging them to take drugs (National Institute on Drug Abuse, 2011).

Herbs are staging a comeback and herbal 'renaissance' is happening all over the globe. The herbal products today symbolise safety in contrast to the synthetics that are regarded as unsafe to human and environment. Although herbs had been priced for their medicinal, flavouring and aromatic qualities for centuries, the synthetic products of the modern age surpassed their importance, for a while. However, the blind dependence on synthetics is over and people are returning to the naturals with hope of safety and security.
