Ketamine: The Complete Guide to Uses, Effects, and Risks

What Is Ketamine?

Ketamiine is a dissociative anesthetic originally developed for medical use in the 1960s. Today, it serves three main purposes:

1. Medical anesthesia (for surgeries and pain management)
2. Mental health treatment (for depression, PTSD, and anxiety)
3. Recreational drug (known for its hallucinogenic effects)

Key Facts About Ketamiine

• Street Names: K, Special K, Kit Kat, Cat Valium
• Forms: Liquid (medical), powder (recreational), nasal spray (Spravato)
• Effects: Pain relief, dissociation, hallucinations, euphoria
• Legal Status:
  • Medical use: FDA-approved (for anesthesia and treatment-resistant depression)
  • Recreational use: Illegal in most countries

How Does Ketamiine Work?

Ketamiine primarily affects the NMDA receptors in the brain, blocking glutamate (a key neurotransmitter). This leads to:
✔ Pain relief (dissociation from the body)
✔ Altered perception (dream-like states, hallucinations)
✔ Antidepressant effects (boosts mood-regulating chemicals)

Unlike traditional antidepressants (SSRIs), which take weeks to work, ketamine can relieve depression in hours.

Medical Uses of Ketamiine

1. Anesthesia & Pain Relief

• Used in emergency medicine (battlefield injuries, trauma)
• Helps with chronic pain conditions (fibromyalgia, nerve pain)

2. Treatment-Resistant Depression

• FDA-approved nasal spray (Spravato) for severe depression
• IV ketamine therapy (administered in clinics)

3. PTSD & Anxiety Disorders

• Reduces fear responses in the brain
• Helps patients process trauma

4. Suicide Prevention

• Rapidly reduces suicidal thoughts in at-risk patients

Recreational Use of Ketamiine

How Do People Use It?

• Snorted (most common recreational method)
• Injected (medical or illicit use)
• Oral (mixed in drinks, but less effective)
• Smoked (rare, usually mixed with other drugs)

Short-Term Effects

• “K-hole” (intense dissociation, feeling detached from reality)
• Euphoria & relaxation
• Visual & auditory distortions
• Impaired motor function (slurred speech, loss of coordination)

Long-Term Risks

• Bladder damage (“ketamine bladder syndrome”)
• Memory & cognitive problems
• Psychological dependence
• Psychosis (with heavy, frequent use)

Ketamine vs. Other Psychedelics

Key Difference:

• Ketamiine is dissociative (feeling “outside” your body).
• LSD & shrooms are classic psychedelics (alter perception but don’t numb the body).

Is Ketamiine Addictive?

Signs of Ketamine Addiction

✔ Craving the drug daily
✔ Using more to get the same effect (tolerance)
✔ Neglecting responsibilities
✔ Failed attempts to quit

Can You Overdose on Ketamine?

• Yes, but fatal overdoses are rare.
• Dangerous when mixed with alcohol or opioids (respiratory depression).
• High doses can cause unconsciousness or severe dissociation.
