What is ketamine and how does it cause addiction?

Ketamine is a dissociative anesthetic that causes detachment from reality, hallucinations, and sedation. While medically approved for anesthesia and treatment-resistant depression, recreational use leads to tolerance and psychological dependence. Users seek the 'K-hole' dissociative state, which can result in compulsive re-dosing and addiction.

What are the signs of ketamine addiction?

Signs include increased tolerance, difficulty controlling use, neglecting responsibilities, memory problems, depression when not using, urinary tract problems (ketamine bladder syndrome), continued use despite negative consequences, and social isolation. Users may appear disoriented, confused, or detached during use.

What are the withdrawal symptoms from ketamine?

Ketamine withdrawal is primarily psychological rather than physical. Symptoms include intense cravings, depression, anxiety, cognitive fog, fatigue, insomnia, and irritability. Withdrawal can last days to weeks. Professional support helps manage symptoms and prevent relapse.

Can ketamine cause bladder damage?

Yes. Ketamine bladder syndrome is a serious condition affecting chronic users. Symptoms include frequent painful urination, blood in urine, urinary incontinence, and permanent bladder damage requiring surgical intervention in severe cases. This damage may be irreversible even after stopping ketamine use.

What is the connection between ketamine and Tussi (Pink Cocaine)?

Tussi (Pink Cocaine) is a polysubstance mixture that typically contains ketamine as a primary ingredient along with MDMA and other adulterants. DEA and UNODC reports confirm ketamine is found in most Tussi samples. Users seeking ketamine may unknowingly consume Tussi, facing additional risks from the unknown drug combination.

Is ketamine legal in New York?

Ketamine is a Schedule III controlled substance. Possession, sale, or use outside medical supervision is illegal in New York. Medical ketamine is used for anesthesia and approved depression treatments, but recreational use carries criminal penalties.

What treatment is available for ketamine addiction on Long Island?

Long Island offers specialized ketamine addiction treatment including psychiatric evaluation (for dissociative-related mental health issues), inpatient rehabilitation, intensive outpatient programs, cognitive behavioral therapy, and support groups. Treatment addresses both the psychological addiction and any co-occurring depression or trauma. Call 631-762-3763 for help.

Can you overdose on ketamine?

Yes. Ketamine overdose can cause respiratory depression, loss of consciousness, seizures, and death. Risk increases when combined with other depressants (alcohol, opioids, benzos) or stimulants (in Tussi mixtures). If someone becomes unresponsive after ketamine use, call 911 immediately.
