There is nothing in the United States anyway that was designed specifically for gambling. There is no drug out on the market specifically for gambling. There are a number of drugs, particularly Naltrexone, in the two forms of it, that seems to have a positive effect of decreasing gambling.

It basically works in two different ways.

One is, if you have less craving towards the involvement in the gambling activity, and two, should you gamble, you're going to get less reinforcement.

It seems to dampen the reinforcement.

We are not substituting opium or another alternative way of feeling good about themselves with a pathological gambling -- what we're trying to do is to mitigate neurological imbalances that evolved as a function of a constant repetition of a behavior such as gambling.
