The main problem with drugs lies in the fact that we are all different. Consider the asbestos problems and huge publicity. The problem affects a certain group of people who are susceptable. If this were not so, then the majority of construction and engineering workers would be dead now.
The same applies to manufactured drugs. If a drug cures or supresses a condition in most people but actually kills a small percentage, then that drug will be considered to have more benefits than risks.
Many thousands of people have taken the same drugs as I but are basically unharmed. There will be a small percentage such as myself that are actually in some way allergic to the drugs. The problem lies in that Doctors do not consider the people who suffer from their prescribing, instead they boast about their successes
