Common Chinese names: K-仔 (K-tzai)

Type of Drug:
Narcotic (dissociative) analgesic with hallucinogenic properties

Liquid ketamine: A clear colourless liquid

Ketamine hydrochloride: Usually found as a white crystalline powder, or it can come in a capsule or tablet form

Ketamine is commonly cut with other substances, often cheaper and more accessible, to increase volume and multiply profits. Substances such as sugars (e.g. lactose, inositol, mannitol), cornstarch, talcum powder, paracetamol, caffeine, glass powder, and washing powder are just a few of the substances commonly found in the final product. Additionally, tablets supposedly containing ketamine are often mistaken for "Ecstasy" (MDMA), or vice versa, which both have completely different side effects to one another.

How is it used:
Medical ketamine is administered via injection and used as a general anaesthetic on children and adults requiring minor operations. However, it is mainly used in veterinarian surgery especially on farm animals e.g. horses

Ketamine hydrochloride is commonly snorted by dividing the powder into thin lines or 'bumps' (a bump is also called a hit of 'K') and snorting it using a straw or a rolled up bank note. The effects take around 5-10 minutes to kick in.

The ketamine capsules and tablets are usually swallowed, and their effects take longer to kick in (10-20 minutes).

Medical ketamine in liquid form can also be used as a recreational drug. In this case it can be injected or drunk. There have been some reported cases where it has been used as a date-rape drug, as the liquid is colourless and therefore harder to detect.

Typical side effects:
- Nausea & vomiting
- Hallucinations e.g. “K-hole” experience
- Numbness in the extremities is also common; hence you can easily hurt yourself and not feel pain which can be dangerous if you need immediate hospital treatment
- Difficulty moving, walking & talking and yet you feel fully awake
- Inhibited sensory input
- Memory loss
- Breathing problems
- Heart failure
- Unconsciousness / coma / death
- Death from an overdose is always possible

Withdrawal symptoms:
The effects of ketamine usually wear off in about 3-4 hours depending on the dosage taken and individual differences.
Withdrawal symptoms might include nausea, vomiting and feeling wobbly on your feet.

Long Term Effects:
The long-term effects of recreational ketamine use are not yet fully understood. There have been recent reports in medical literature that link a serious reduction of bladder function in ketamine users. As a result users end up needing to go to the bathroom every 15 minutes or even less.

Frequent use can cause disruptions in consciousness and lead to neuroses or other mental disorders.

Sever psychological dependence and addiction is also highly probable
