I am not actually sure how you are criticising my argument. The medical proffesion is only interested in the first instance in “problem” addictions that can be easily studied. I am using a definition that most people are aware of. E.g I am addicted to chess, ping-pong, chocolate cake, internet etc. My point is all these harmless addictions/past-times involve behavioural change, in some cases as strong as that motivates heroin addicts, though not at a conscious level [involving say obvious withdrawal] like heroin addiction. Most of my behaviour seems to me to be controlled subconciously, with my concious occassionally making pitiful efforts to regulate my behaviour {no you are not going to eat that chocolate - Ok then only one - well perhaps two but no more…} but mainly acting as observer. When I get very involved in something (for a while it was bridge), something must be triggering pleasure circuits in my brain for me to keep going. These are often the same pleasure circuits that many drugs hit, but just more intensely.
At the moment I am addicted to silly games on my palm pilot - backgammon in particular. Will often spend 1-3 h day playing when I should be doing something else. This board is also a bit of an addiction for me. Luckily, they are pretty harmless, and may actually be good for my brain cells, but IMHO I am addicted in the same way a heroin addict is. I get a burst of pleasure when I win a game, or am able to answer a question first (pitiful huh?). Many marriages have broken up because of a persons addiction to say the internet, or gambling. Are you saying (i) you cannot get behavioually addicted? or that (ii) behavioural addictions are not related to the same brain pleasure circuits as drug based addictions or (iii) an addiction is only an addiction when it is a medical problem?
I looked up the addiction site you mentioned. Couldn’t find any definition of addiction there! They seem only interested in alcoholism and other chemical addictions. They leave the behavioural addictions to their physcology friends.
