Substance abuse, also known as drug abuse, is a patterned use of a drug in which the user consumes the substance in amounts or with methods which are harmful to themselves or others, and is a form of substance-related disorder.

Widely differing definitions of drug abuse are used in public health, medical and criminal justice contexts.

In some cases criminal or anti-social behavior occurs when the person is under the influence of a drug, and long term personality changes in individuals may occur as well.

In addition to possible physical, social, and psychological harm, use of some drugs may also lead to criminal penalties, although these vary widely depending on the local jurisdiction.

Major trauma is any injury that has the potential to cause prolonged disability or death.

There are many causes of major trauma, blunt and penetrating, including falls, motor vehicle collisions, and stabbing and gunshot wounds.

Depending on the severity of injury, quick management and transport to an appropriate medical facility (called a trauma center) may be necessary to prevent loss of life or limb.

The initial assessment involves a physical evaluation and can also include the use of imaging tools to accurately determine a type of injury and to formulate a course of treatment.

Various classification scales exist for use with trauma to determine the severity of injuries, which is used to determine the resources used and for statistical collection.

The initial assessment is critical in determining the extent of injuries and what will be needed to manage an injury, and treating immediate life threats.
