Fentanyl is a white powder. It can be mixed with water and injected with a needle. Fentanyl can also be smoked or snorted up the nose. Fentanyl causes a rush of good feelings just after it’s taken. But some people throw up or itch after taking it. For the next several hours you want to sleep, and your heart rate and breathing slow down. Then the drug wears off and you may feel a strong urge to take more.

Synthetic Opioids give you a feeling of well-being and happiness. It also makes you feel like the world has slowed down, and all of life’s problems are suddenly okay. People on Synthetic Opioids might move and think slowly, fall asleep uncontrollably or even standing up, slur their words, and have dilated pupils (the black circle in the center of each eye gets very small).Synthetic Opioids are extremely addictive. They are usually injected intravenously (shot up), snorted (taken nasally), or smoked using tin foil. These methods send the chemicals to the brain very quickly, and the user feels an instant rush of dopamine.
