Yes I did, because 'drug abuse' isn't a useful or clearly defined term. Eg. if I search for a definition, in the first few hits I get: "The use of illegal drugs or the use of prescription or over-the-counter drugs for purposes other than those for which they are meant to be used, or in excessive amounts." "Substance abuse, also known as drug abuse, is a patterned use of a drug in which the user consumes the substance in amounts or with methods which are harmful to themselves or others, and is a form of substance related disorder. " The first definition will vary based on your local laws, which as we have seen, are also subject to change. So if that's the meaning of the term 'drug abuse' it's not particularly useful to discuss since it's a technicality. The common factor between the two definitions (excessive, harmful consumption) might be more useful to discuss. Which was why I chose to talk about that (rate of consumption, risk of addiction) specifically.
