The psychological urge to consume a substance and the relentless feeling of dependence on that substance leads to addiction. Such addiction is also known as drug or substance addiction. Substances which affect the nervous system of the body are more likely to cause addiction. Some examples of such substance are caffeine, nicotine, alcohol, stimulants, anti depressants, pain relievers, and morphine among others.
The addiction is faster and more in case the substance is inhaled or injected. With regular administration of such drugs, the body develops a tolerance level to the drug so much so that once the individual decides not to consume the substance; there are severe withdrawal symptoms in the body. The withdrawal symptoms can range from headache to dizziness to increase in blood pressure and heart rate. At times such withdrawal symptoms can also be fatal and thus de-addiction should always be gradual and under medical supervision.
Addiction not only affects the physical health of the individual but it also affects the mental, emotional and financial health of the individual while creating a menace for the society and the well wishers. Thus, addiction should be immediately treated. The treatment gives better results in case the individual realizes the consequences and willingly wants to come out of such addiction. Depending on the substance of addiction, quantity and duration of such substance addiction, and the individual’s health and age factors, the treatment of addiction can range from out-patient facility to in-patient facility.
