    Is Addiction a psychological or physical curse?
    1/ Smoking is addictive, but because of a physical rise in nicotine levels, the mind decides that new level of nicotine is the new equilibrium.
    2/ Gaming is addictive (to the sad ones) but there is no physical desire to game. Its purely intrinsic and mental. The mental state of being in another world is what hooks people.

    Hmmmmmmmmm

    Peace G's


    hell yeh

    Seems you've answered your own question. It's psychological, physical and both depending on the situation.

    as above, its typically a mixture of both.

    as far as I'm aware, addictive drugs all lead to an increase in dopamine levels in the reward pathway in the brain. Normal conditions, such as a desire to get food or to procreate, leads to activation of the reward pathway.

    Memory formation also occurs, by all accounts, which leads to a degree of craving, coupled to the physical withdrawal (due to the unnatural equilibrium formed, such as getting used to nicotine levels mentioned) results in relapse.

    these memory's can be permanent.

    So if someone is addicted to nicotine, they will both need the nicotine to restore function in systems which have been changed, they will also want the reward - triggered by certain memory's, such as the smell of smoke.

    Interestingly - the RUSH phenomena has a huge part to play in the level of how addictive a substance. cigarettes are far more additive, than sunff, which is far more addictive than slow release patches designed to take the edge of withdrawal (with out the rush) .

    Edit - i neglected the gambling part, because I'm not familiar with this as an illness. but i believe there is a biological basis, mentioning noradrenaline and adrenaline i guess might give you something to research.

    If you we only know which genes tigger people to be addicted, then it will solve many unanswered question we might have. Anything we do access is always consider as addiction. It is not only smoking, or gambling. It can be anything you think of. If you we look addiction from theortical points then one will find it is because pleasure we get from. Then can one argue and say "pleasure" is form of addiction. I don't think that there is only one reason why people are addicted to things they are addicted too. We can say people are addicted to "money" which can lead to many catastrophy. Now lets talk about neurobehavior of man kind and neurotransmitter which intrigue to many things that we called "addiction". But to me every addiction are controble and how do we control our needs. And need is the biggest addiction anyone can have...

    "Pleasure" can only be a form of (classified) addiction, if it has a dramatic effect on the mesocorticolimbic dopaminergic reward pathwa. This ties into what I mentioned above as RUSH being a key factor in addictiveness of a substance. [Addiction and withdrawal ó current views, Jan K Melichar et al, Current Opinion in Pharmacology]

    I'm going to use an example of something friends of mine enjoy and assume that they find it so enjoyable because it stimulates the reward pathway, hence the enjoyment.

    Mild pleasure, such as going for a bike ride might stimulate the reward pathway. But despite this increase in dopamine levels they will not develop a tolerance, spend excessive amounts of time riding the bike and let it affect their social and work lifeís (which are part of the classification of addiction). What Iím trying to say is that clinical addiction is not just pleasure on, so the person says so letís keep doing this . Pleasure on its own is the natural reward system, (e.g. food and sex). Something happens in addiction which is different to just pleasure.

    Addicts find it pleasurable; but it has a huge and lasting affect on their physical behaviour, such as affecting motor coordination, thus they want to keep doing it, suffer withdrawal if they stop and memory cues associated with their addiction trigger a craving. The lasting effect can be noted in experiments which look at metabolic activity of brains of addicts, where it is noted that there is rewiring of the brain circuitry

    Factors which can cause these addictive properties include genetics (probably very much so) of the individual making them predisposed to addiction. One suggestion for example could be isoforms of the dopamine receptors or polymorphisms causing an exaggeration of the reward pathway. and indeed the speed at which the reward is felt.

    I kind of ranted on a little there, but I donít feel its right to suggest that pleasure is addictive on its own. Other factors must be present.

    *note Ė My knowledge of addiction is limited and although true in what I have been saying, itís directed at substance abuse more so than any other addiction, although I also believe there is a biological cause for both.
