Hint: Any substance which causes a change in an organism's physiology or psychology when it gets consumed are called drugs. Drugs are typically different from food and substances which provide nutritional support to our body. Consumption of drugs can be done by inhalation, injection, smoking and ingestion. It can also be consumed by absorption as a patch on the skin and also through the dissolution under the tongue.
Complete step by step answer: When it comes to the medicines they all have different side effects. Each medicine level contains different amounts of dosages which should be followed strictly for the proper nutrition support. If these levels are exceeded as compared to the requirements then it can cause more harm than good. Drug overdose may be fatal due to toxicity. That’s why, due to the harmful and poisonous nature of a drug, it should not be taken without proper medical advice. In many countries, there are various governmental offices which are used to deal with the maintenance of drug manufacture and its use. And also the implementation of various drug laws. In 1961 , a Single Convention on Narcotic Drugs was an international treaty brought with the principle to prohibit the use of narcotics. In 1971 , a second treaty, the Convention on Psychotropic Substances had to be introduced to deal with newer recreational psychoactive and psychedelic drugs.
Note: In the united states, the Food and Drug Administration (FDA) is a federal agency which is responsible for protecting and promoting the public health by doing the regulation and supervision of food safety, tobacco products, dietary supplements and so on.
