Ketamine is a drug that is used on both animals and humans. A chiral (chemistry term meaning that there is a lack of internal plane symmetry) compound, ketamine is denoted by the chemical formula C13H16ClNO. It is basically an anesthetic drug but is also being used for a variety of purposes. It can be bought in various forms today - Ketanest, Ketaset, and Ketalar.
Medically, ketamine is used as a pediatric anesthetic agent, usually in conjunction with other medication such as muscle relaxants. It is also used to help patients suffering from obstructed breathing passageways, such as those who have asthma. Some creams and gels contain ketamine as well - these are used mainly to help deal with nerve pain. More so, ketamine is used for emergency purposes such as medical procedures in war zones and those who suffer from trauma.
A more controversial use of ketamine is as a recreational drug. As with other recreational drugs, the idea is not held in good esteem by the general public. In fact, the use of ketamine for this purpose is not legal and has even been labeled hazardous. It has not prevented people from using ketamine recreationally, though, as it has the effect of inducing vivid hallucinations. According to those who have used the drug, the experience is quite intense, but the memories do fade easily once the effects have worn out. This is due to the fact that ketamine does have the strong potential to damage brain cells and cause serious memory problems.
