Well the line linking harmful substances and their help isn’t clear yet. Many people think that there are good drugs such as different types of medicine and bad drugs like cocaine, heroin etc. But the fact is that drug is just a drug no matter whether it’s good or bad, the over usage of it will definitely affect your health. Usually all drugs are considered as poisons, however in what amount you are taking it determines its effect i.e. positive or negative. Most drugs merely cover the pain and discomfort for e.g. a medicine Aspirin which doesn’t cure a headache, but simply affect the person’s mind to stop the pain messages from the cause of headache. The actual cause of headache like nutritional deficiency or physical problem still lies as it is. Although it is true that lots of drugs seems to help person fighting the severe cause, but you can’t neglect the fact that they have adverse effects too. Some people use several medicines (aka drugs) to overcome the substance abuse problems like the use of cocaine, heroin, marijuana, alcohol etc. but they should understand that to cure such problems they are still laying on other drugs which are truly not good. There are drug-free alternative like http://greenestone.net/treatment/treatment-program/ rehabilitation center and many more out there to help people overcome such addiction without any medicines. The treatment programs conducted by such rehab centers are going extremely successfully all over the world and now people doesn’t hesitate to go over to cure these problem. Hence at last I would say that don’t use any type of medicine without prescribed by a doctor and completely avoid the use of illegal drugs too.
