Signs of Use
Since Fentanyl is a prescribed drug, people often do not follow the medication prescribed and use it as they want.
Not following the Prescription
This is the most common sign when it comes to Fentanyl abuse. When Fentanyl is prescribed, it is prescribed for a short duration with a limited dosage. An addict would take the Fentanyl pills as he pleases, as well, and in quantity much more than recommended.
Consuming powder or another form
The Fentanyl prescribed by doctors is usually in the form of pills, but people also take powder or shots. Since it has evolved as a street drug, it is also mixed with other stuff to add to its potency.
Calmness and unexplained intoxication
Fentanyl acts on the receptors in the brain to impose a calming effect as well as intoxication.
