Addiction to anything beyond control is harmful. It not only harms the individual but affects the society at large. Specifically when addiction is to a harmful substance, it is even more harmful. Such addiction is also known as substance or drug abuse or addiction. This substance abuse goes to an extent that the patient has a compulsive urge to consume the substance even when that individual knows that such a substance harms the physical, metal, financial and emotional health of the individual.
The compulsive urge is so severe that in case the individual wishes to come out of such addiction, there are grave withdrawal symptoms. Such symptoms can range from headaches, dizziness to severe rise in blood pressure and heart beat rate. At times, the withdrawal symptoms can also go out of hand and prove to be fatal for the individual.
