Suicide prevention is an umbrella term for the collective efforts of local citizen organizations, mental health practitioners and related professionals to reduce the incidence of suicide. Beyond just direct interventions to stop an impending suicide, methods also involve a) treating the psychological and psychophysiological symptoms of depression, b) improving the coping strategies of persons who would otherwise seriously consider suicide, c) reducing the prevalence of conditions believed to constitute risk factors for suicide, and d) giving people hope for a better life after current problems are resolved.
General efforts have included preventive and proactive measures within the realms of medicine and mental health, as well as public health and other fields. Because protective factors such as social support and connectedness, as well as environmental risk factors such as access to lethal means, appear to play significant roles in the prevention of suicide, suicide should not be viewed solely as a medical or mental health issue.

Pharmacology (from Greek φάρμακον, pharmakon, "poison" in classic Greek; "drug" in modern Greek; and -λογία, -logia "study of", "knowledge of") is the branch of medicine and biology concerned with the study of drug action, where a drug can be broadly defined as any man-made, natural, or endogenous (within the body) molecule which exerts a biochemical and/or physiological effect on the cell, tissue, organ, or organism. More specifically, it is the study of the interactions that occur between a living organism and chemicals that affect normal or abnormal biochemical function. If substances have medicinal properties, they are considered pharmaceuticals.
