Harm Potential

Addiction & Dependence

Psychological

High

Classified as habit-forming with effects similar to heroin, morphine, and fentanyl, suggesting significant psychological addiction potential consistent with other potent opioids.

Physical

High

Physical dependence develops with repeated use. Withdrawal symptoms similar to other opioids have been observed, including depression and insomnia.

Toxicity

Respiratory

Respiratory depression is a primary concern and has been implicated in fatalities; the substance may be approximately 1.6 times more potent than morphine for respiratory depression, meaning dangerous effects may occur close to analgesic doses.

Cardiovascular

Tachycardia and hypertension have been reported during overdose situations.

Seizure Risk

Seizures have been reported during overdose situations.
