Using heroin will most likely affect Alejandra's body systems in multiple ways:
1. It will fill the lungs with toxic material: Heroin is typically injected into the veins, and while it does not directly fill the lungs, the impurities and contaminants present in the drug can make their way into the bloodstream and potentially affect lung function over time.
2. It will release serotonin and dopamine to the brain: Heroin acts as a central nervous system depressant, and upon ingestion, it quickly converts to morphine and binds to opioid receptors in the brain. This binding triggers the release of large amounts of neurotransmitters like serotonin and dopamine, resulting in a euphoric and relaxed state.
3. It will block the transmission of pain signals to her brain: Heroin, being an opioid, has analgesic properties. It binds to opioid receptors in the brain and spinal cord, interrupting the transmission of pain signals to the brain, which can produce a numbing effect.
4. It will slow down the central nervous system: By binding to opioid receptors in the brain and central nervous system, heroin depresses the activity of these systems, resulting in slowed breathing, decreased heart rate, and overall sedation.
It's important to note that heroin use can have severe and potentially life-threatening consequences. If someone is struggling with drug addiction, it's crucial to seek professional help and support.
