Disulfiram

Disulfiram is Antabuse® and interferes with degradation of alcohol, resulting in the accumulation of acetaldehyde, which, in turn, causes a very unpleasant reaction to alcohol intake. The effects include flushing, nausea and palpitations. Compliance with the disulfiram is generally poor, so physicians consider the utility and effectiveness of disulfiram limited. However, among patients who are highly motivated, disulfiram can be effective especially for some patients in risky situations, such as social occasions where alcohol is present. Patients can receive disulfiram in a clinic or by a spouse, improving its efficacy.

Ketamine

At lower doses, ketamine acts a weak stimulant. When dosage increases, ketamine hits users as an intense psychedelic. As a dissociative drug, ketamine causes users to feel painlessness by impeding messages between the brain and body. Ketamine distorts perception and users often experience an effect known as "the K-hole" at high doses, where the reality of a user involves abstracted thought and pseudo-spiritual experiences. In fact, many ketamine users report depersonalization and de-realization, causing out-of-body or near death experiences. While some ketamine users find these dissociative effects pleasant, others experience them as a deep sense of loneliness or emptiness. Hallucinations, both visual and auditory, can also take place during a ketamine trip. Ketamine trips do not tend to lend themselves to social interaction at high doses, but are introspective experiences as users withdraw into themselves. Within 10 to 20 minutes, the effects of ketamine become discernable for users. Muscle paralysis sets in, making it difficult to move. Ketamine users often fall into a "trance" state, finding themselves encountering difficulty speaking and cognitively processing. Ketamine trips are short lived, lasting between 45 minutes and an hour and a half, depending on tolerance. Users often feel drained and exhausted after a ketamine trip and muscle aches often tend to set in as users come down from a ketamine high. Ketamine users experience temporary paralysis of the muscles, loss of physical coordination and become prone to accidental falls and injuries. Research studies indicate that ketamine addiction can lead to brain damage, particularly the formation of vacuoles, also known as "Olney’s lesions." Ketamine use does not usually result in overdoses from self-administered use, largely because unconsciousness sets in before the body reaches the level of overdose. However, if ketamine a user intakes ketamine from a third party, overdose can occur if dosage continues after loss of consciousness.

Casino security refers to the measures that are taken at casinos to protect the establishment's money and property and the patrons. The security protects the casino and its customers from violent crime, theft, and other inappropriate behavior.

Given the relatively large amounts of currency that are handled within a casino, the temptation exists for both patrons and staff to commit crimes. Many casinos take security measures to prevent theft and other crime. The most basic level of security today consists of cameras located throughout the property operated by highly trained individuals who attempt to locate cheating and stealing by both players and employees.

While casino security of the past was nothing more than a muscle man, today's security is a multi-million dollar investment that is as complex as a police department. Modern casino security is usually divided between a physical security force and a specialized surveillance department that operates the casino's closed circuit television system known in the industry as the eye in the sky in an effort to detect any misconduct by both guests and employees alike. Both of these specialized casino departments work very closely with each other to ensure the safety of both guests as well as the casino's assets, and have been quite successful in preventing crime. Some casinos also have catwalks in the ceiling above the casino floor. These catwalks allow surveillance personnel to look directly down, through one-way glass, on the activities at the tables and/or slot machines.

In addition to cameras and other technological measures, casinos also enforce security through rules of conduct and behavior; for example, players at card games are usually required to keep their hands visible at all times.

The amount of security that is used at a casino is determined based on local laws and ordinances and what the prosecutors in the region are willing to act upon.

Internet Casinos

Online casinos, also known as virtual casinos or Internet casinos are online versions of traditional brick and mortar casinos. Online casinos enable gamblers to play and wager on casino games through the Internet.

Online casinos generally offer odds and payback percentages that are comparable to land-based casinos. Some online casinos claim higher payback percentages for slot machine games, and some publish payout percentage audits on their websites. Assuming that the online casino is using an appropriately programmed random number generator, table games like blackjack have an established house edge. The payout percentage for these games is established by the rules of the game.

Many online casinos lease or purchase their software from companies like Microgaming, Realtime Gaming, Playtech, International Game Technology and CryptoLogic Inc.

Online casinos can be divided into two groups based on their interface: web-based and download-only casinos. Some casinos offer both interfaces.

Some casinos offer 'Live gaming', either exclusively, or as part of a wider online casino offering. In live online casinos, popular casino games such as roulette and blackjack are dealt by real dealers in casino studios, in an attempt to convey more of the atmosphere of a physical casino. Player actions including chat such as 'hit' in the game of blackjack may be transmitted to the dealer; in some online casinos more than one player may 'sit' at a particular 'seat' on the table, and in this case there is no interactivity between player and dealer, the question of which players requested the extra card that the dealer dealt and which chose to 'stand' will be handled by the software. It is usual for players to be able to observe a video feed of the action, and equally common for players to opt to turn it off, if they lack the bandwidth - as the cards are read by OCR and other technology, the video feed is only ever a visual cue.

Web-based online casinos are websites where users may play casino games without downloading software to the local computer. Games are mainly represented in the browser plugins Macromedia Flash, Macromedia Shockwave, or Java and require browser support for these plugins. Also, bandwidth is needed since all graphics, sounds and animations are loaded through the web via the plugin. Some online casinos also allow gameplay through a plain HTML interface. Apple devices such as iPod, iPad and iPhone cannot play Flash games as the technology is not supported.

Download-based online casinos require the download of the software client in order to play and wager on the casino games offered. The online casino software connects to the casino service provider and handles contact without browser support. Download-based online casinos generally run faster than web-based online casinos since the graphics and sound programs are located within the software client, rather than having to be loaded from the Internet. On the other hand, the initial download and installation of a download-based online casino client does take time. As with any download from the Internet, the risk of the program containing malware does exist. Still the graphics and sounds at download-based online casinos are most of the time much better than those at web-based online casinos.
