People begin using drugs because of a number of reasons. There are those who will begin using it just to see how they will feel like with it. Irrespective of the reason, drug use can turn into drug abuses which will subsequent lead to dependence which is then called drug addiction. This occurs since the body reaches a state where it becomes tolerant to the drug to the extent that the user will need more of it in order to feel the same sensation. In needing such initial high, the body’s functionality becomes dependent on the drug, thus making the body system dependent on the drug (NIDA, 2016).
Majority of drugs consists of chemicals. Because of the chemical elements inherent in different drugs, use of such can negatively affect the functioning of the body in a number of ways. Research indicates that some of these drugs can continue affecting the brain and general body long after the person stopped taking such drugs. Furthermore, the manner in which the drug enters the body, that is whether through ingestion, inhalation, injection or oral taking determines the kind of effect it is likely to cause to the person. For instance, if the method used is through injection, the drug will enter the blood stream directly and thus cause immediate effect. In the event that the method is through injection, the drug will go through the digestive system, thus delaying the effects (Nutt et al, 2007).
While the effect of drug abuse on an individual can differ as per the drug that has been abused, majority of drug abuse cause negative ramification on the body’s health. Among the common effects of drug abuse on the body include decreased memory, changes in sleep and an impact on cognitive abilities. In addition, there are also other physical problems of drug abuse which may include impotence, regular illnesses, excessive respiration, high blood pressure, HIV because of need-sharing, hepatitis B or V, lung or chest pain among others (Peterson, 2013).
