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.
