Gambling alone receives a very bad wrap, but online casinos and online gambling has been accused of everything shy of being created by the devil.  There is a lot of money involved in online casinos so there is certainly a lot of interest.  From players to operators there is a chance to benefit big time financially.  That may be the simple draw to online casinos, but people seem to be looking for some deeper, almost demonic, reason for it.

Yes.  Gambling addiction is a serious problem.  But one form of gambling does not generate gambling addiction over another.  Games do not create gambling addiction, people either have an addictive nature or they do not.  Slot machines have been called the crack cocaine of slot machines, but that is not because slot machines are more addictive than poker.

Slot machines simply require far less skill than poker and not much learning is required to play the games.  More player play slot machines than any other casino game in general so it will follow that you will find more gambling addicts and slot machines.

The fear with online casinos is that is the pure convenience will generate more problem gambling, but once again the logic does not make sense.  A problem gambler will not make something like a short drive to the casino stand in between them and their fix.  The only really threat that online casinos pose to gambling addicts is that it may be harder for them to get help.  A gambling addict can get carried away in their own home and it will not be as evident as a addict constantly taking trips to the casino.
