Opinions vary greatly on the effects of steroid use. Although medical research is being conducted there is a divide amongst experts as to the effect of steroid use. Some of the users will write articles on the internet that is totally positive about the advantages of such use and the medical profession will write a negative article whilst both are discussing the same symptoms. It is well known that drug users will always try to justify their habit by producing facts and figures or even research that shows that their habit is not dangerous and causes no ill effects. The medical profession will offer views, supported by statistics that prove that drug use causes great harm, not only to themselves but to their families and friends indirectly. They will also argue that medical facilities are stretched by having to deal with self-inflicted illnesses and the weakness of those people taking steroids. Steroids are used by the medical profession to treat illnesses such as asthma and it is understandable that they resent misuse of such a drug when they are seeing the side effects that it has on their genuine patients. People will always be tempted by the lure of drugs as it is the lazy way to solve their problems and get a quick fix whether it is to enhance performance, to look better, or just to make them feel good temporarily.
