Quick info

Ketamine is a synthetic anesthetic and belongs to the group of dissociatives. Its effects are highly dependent on the amount consumed. Ketamine is usually used in low doses as a party drug, but in higher doses it can trigger strong out-of-body, psychedelic experiences ("K-Hole"). Ketamine is also used in psychiatry as a quick-acting antidepressant for treatment-resistant depression.

Effect

The effect of ketamine as an intoxicant is strongly dependent on the dosage: in lower doses it has a disinhibiting and relaxing effect, similar to alcohol, while higher doses can induce trance-like states up to out-of-body or near-death experiences ("K-Hole"). There may be a fragmentary dissolution of the environment and bodily sensation, thoughts may break off, feelings of weightlessness or floating may emerge. Sensory perceptions and the space-time sensation change.

At very high dosages, detachment from one's own body and/or ego dissolution or fusion with the environment may occur. After the trip: drowsiness, memory of the experience is often only partially possible.

Duration

Onset of action:
Snorted: after 5 - 10 minutes
Swallowed: after 15 - 20 minutes
Injected intramuscularly: 2 - 5 minutes
Injected intravenously: within seconds
‍‍

Duration of effect:
45 minutes - 2 hours depending on dose and form of consumption.

Dosage

The dosage of ketamine is highly dependent on the desired effect. In party settings, usually only a few milligrams are snorted to achieve the desired effect. A higher dosage produces a more intense effect and is not recommended in party settings.

Snorted
Light: 10 - 30 mg
Medium: 30 - 75 mg
Strong: 75 - 150 mg

Swallowed
Light: 50 - 100 mg
Medium: 100 - 300 mg
Strong: 300 - 450 mg

Injected intramuscularly
70 - 150 mg

Injected intravenously
~ 50 mg

Forms of appearance
‍white
crystalline powder, crystals ("rocks") or small rods ("needles"). Rarely liquid as a solution.

Risks

  • In combination with alcohol, GHB/GBL, benzodiazepines or opiates there is a risk of respiratory arrest!
  • Mixing with uppers (e.g., amphetamine or cocaine) can cause circulatory problems, increase heart rate, and shortness of breath.

Safer Use

  • Do not take high doses of ketamine alone, and make sure the environment is as familiar and comfortable as possible. Allow enough time to process the trip in peace afterwards.
  • Dose carefully. Small differences in dose can cause significant differences in effect.
  • Take regular breaks from use. Ketamine has a psychological dependence potential.
  • You need a place to sit or lie down, because at high doses there is a great risk of collapsing or fainting.
  • Because of the insensitivity to pain, you can hurt yourself without noticing it.
  • Do not take ketamine on a full stomach due to possible nausea.
  • People with cardiovascular problems, high blood pressure or glaucoma should absolutely refrain from consuming ketamine!

Mixed use

  • In combination with alcohol, GHB/GBL, benzodiazepines or opiates there is a risk of respiratory arrest!
  • Mixing with uppers (e.g., amphetamine or cocaine) can cause circulatory problems, increase heart rate, and shortness of breath.

Increased risk

We strongly advise against this combination. If possible, stick to a single substance. The health risks are significantly increased—including the risk of overdose, respiratory and circulatory problems, and mental health crises.

Lower risk

Learn about the substances, their effects, how quickly they take effect, and the proper dosage. Get to know each substance on its own first, and see how they affect you and whether they suit you before mixing them. Allow enough time between doses, mix as few substances as possible, and start with low doses.

Risk

This combination already poses a significant risk. The effects can reinforce each other or change in unpredictable ways. Therefore, use these substances with caution, test new or unfamiliar substances individually first, and keep the doses as low as possible. Allow sufficient time between doses and avoid taking additional doses on a whim. Be aware of the varying durations of action for each substance.
