Fentanyl creates a short, but intense high. The euphoric feelings and short duration cause users to take it often, greatly increasing the risk for addiction. Besides euphoria, this drug also creates extreme happiness and relaxation, which is why it works well for pain.

On the other hand, some side effects of fentanyl use are very serious. Users should be aware that respiratory depression and seizures are side effects of fentanyl use. Fentanyl is a synthetic opioid that works by interacting with opioid receptors found on some nerve cells. These receptors are found throughout the brain, along the spine, and even in the digestive tract. When opioids like fentanyl attach to them, the brain is flooded with a feel-good chemical called dopamine.

This blocks pain messages relaxes the central nervous system and creates a feeling of euphoria. Opioids trigger the brain to release other chemicals called endorphins. Endorphins fill the space between nerve cells and are naturally produced to help a person cope with stress or pain. Like dopamine, endorphins also create feelings of happiness while reducing pain.

But fentanyl causes an unnatural surge of endorphins, which may create a dependency on the drug to feel good. The powerful effects that fentanyl has on the brain makes it highly addictive. When taken illicitly or for a long period of time, the brain gets used to the changes that fentanyl brings. When stopped, withdrawal symptoms begin as the brain can no longer create the necessary chemicals to function normally.

These symptoms can be extremely uncomfortable and sometimes deadly. There are several factors that can influence how long fentanyl stays in your system. Some factors are physical traits that determine your ability to metabolize the drug, and include:.

Age, weight, and even body fat make a difference in how your body processes and removes a drug. For example, using a drug for a long period of time can cause it to build up and stay in the system longer. If people use multiple drugs or take them with alcohol, the drug may also stay in the system longer.

Drugs have a half-life, which is a time used to determine how long it will take half of the drug to leave the body. The half-life of fentanyl is 5 to 15 hours. This means it will take 5 to 15 hours to remove half of the drug. After that, it will take another 5 to 15 hours to eliminate half of what is left.

Therefore, one dose of fentanyl will take anywhere from 25 to 75 hours to completely leave the system. Fentanyl is a synthetic opioid, meaning there are no natural ingredients. Therefore, it does not break down into the same metabolites as opioid products made from poppy plants. She also has experience with admissions, marketing, and outreach.
