Tweedle24, in this day and age, even drug addiction is not as clear cut as saying they should not have have started them. Many, many start out on prescription drugs issued by their Dr's and find themselves sliding into addiction without even realising it. Once they are denied prescriptions by their GP's, they then find themselves in a terrible cold turkey situation and buy the drugs online or a dealer. My DB never considered himself an addict because he didn't do cocaine, heroine or the like. He brought prescription drugs off the internet which eventually killed him. Even as an addict, the GP still prescribed him addictive drugs and we believe that is why he didn't stay clean. After all, if your GP knowingly prescribes them, they must be ok.
As for the "inhumane acts" people do when they are desperate for money for drugs, or driving a car whilst under the influence, of course it is completely wrong, terrible for the victims, etc., but it doesn't mean you can't have compassion for the underlying problems that exist which have led that addict to the place they are at.
