I will suggest you are suffering from some kind of prejudice or bias. Doctors prescribe drugs all the time for beneficial purposes. Caffeine, found in chocolate, coffee, and sodas, is also a drug. Mos spices have medicibal uses. Etc.<p>Many drugs have an impact on your mental state.<p>I personally suspect that if someone has an addiction they cannot break, there is probably some underlying problem fueling it, possibly a physical health issue. So saying drug use is associated with wreckage and death....cancer leads to drug use and wreckage and death. But sometimes, cancer leads to drug use that averts death, though at a cost.
