Concept

Substance abuse

Overview

Substance misuse, also known as drug misuse or, in older vernacular, substance abuse, is the use of a drug in amounts or by methods that are harmful to the individual or others. It is a form of substance-related disorder. Differing definitions of drug misuse are used in public health, medical, and criminal justice contexts. In some cases, criminal or anti-social behavior occurs when some persons are under the influence of a drug, and may result in long-term personality changes in individuals. In addition to possible physical, social, and psychological harm, the use of some drugs may also lead to criminal penalties, although these vary widely depending on the local jurisdiction.

Drugs most often associated with this term include alcohol, amphetamines, barbiturates, benzodiazepines, cannabis, cocaine, hallucinogens, methaqualone, and opioids. The exact cause of substance abuse is sometimes unclear, but there are two predominant theories: either a genetic predisposition or a habit learned or passed down from others, which, if addiction develops, manifests itself as a possible chronic debilitating disease. It is not easy to determine why a person misuses drugs, as there are multiple environmental factors to consider. These factors include not only inherited biological influences (genes), but there are also mental health stressors such as overall quality of life, physical or mental abuse, luck and circumstance in life, and early exposure to drugs, all play a significant role in how people will respond to drug use.

In 2010, about 5% of adults (230 million) used an illicit substance. Of these, 27 million have high-risk drug use—otherwise known as recurrent drug use—causing harm to their health, causing psychological problems, and or causing social problems that put them at risk of those dangers. In 2015, substance use disorders resulted in 307,400 deaths, up from 165,000 deaths in 1990. Of these, the highest numbers are from alcohol use disorders at 137,500, opioid use disorders at 122,100 deaths, amphetamine use disorders at 12,200 deaths, and cocaine use disorders at 11,100.

The determinations of a substance, which are only particular modes of its existence, are called accidents. They are always real, because they concern the existence of substance (negations are only determinations, which express the non-existence of something in the substance). Now, if to this real in the substance we ascribe a particular existence (for example, to motion as an accident of matter), this existence is…

Assumptions of this kind about the nature of sexual desire have found acceptance in the mind of the people since the beginning of time; love is called an “intoxication,” it can be induced by “potions”—in these ideas the agency at work is to some extent projected on to the outer world. We find occasion at this point to remember the erotogenic zones, and to reflect upon the proposition that sexual excitation may arise…

For there are two kinds of poisons used among men, which cannot clearly be distinguished. There is the kind just now explicitly mentioned, which injures bodies by the use of other bodies according to a natural law; there is also another kind which persuades the more daring class that they can do injury by sorceries, and incantations, and magic knots, as they are termed, and makes others believe that they above all…
