What are the effects when combining seroquel with heroin?

Combining Seroquel (quetiapine) with heroin can lead to dangerous effects due to the sedative properties of both substances. This combination can significantly depress the central nervous system, increasing the risk of respiratory failure, coma, or death. Users may also experience heightened sedation, confusion, and impaired motor function. It is crucial to avoid such drug interactions and seek professional help if needed.
