Occasional drinking or smoking, though not recommended is not very bad. In certain cases, people who smoke or drink become too reliant on the intoxicants and stimulants to do the normal works of life. This is what causes excessive reliance on the substance. At times, it can lead to prolonged substance abuse and becomes an addiction. When you or any person in your family or friends is addicted, the best way to treat is to reach out to a de addiction centre in Chennai. Serene Life Hospital is a leading center that offers deaddiction therapies to everyone.
