Prescription and illegal opioids are commonly abused because they are so addictive.
Opioid medications bind to the areas of the brain that control pain and emotions, driving up levels of the feel-good hormone dopamine in the brain's reward areas and producing an intense feeling of euphoria.
As the brain becomes used to the feelings, it often takes more and more of the drug to produce the same levels of pain relief and well-being, leading to dependence and, later, addiction.

Oxymorphone hydrochloride – Oxymorphone hydrochloride, under the name Opana ER, was at the center of an HIV outbreak in Indiana in 2015. Some addicts began injecting and shared needles increased the spread of HIV.
In June, the Food and Drug Administration requested that Opana ER manufacturer Endo Pharmaceuticals pull the drug from the market. It was the first time the agency has asked that a opioid pain medication be pulled "due to the public health consequences of abuse." Endo announced in July that it would pull the drug.

Codeine – Codeine is one of the weakest opioids, often given when painkillers such as acetaminophen or ibuprofen fail to work. Because it decreases activity in the part of the brain that controls coughing, it's frequently mixed with other liquids to develop cough syrups for colds and flu. It has frequently been used for pain relief after removal of tonsils and adenoids in children.
After an investigation, the FDA restricted the use of codeine and tramadol in children under 12 and recommend against their use in children between 12 and 18 years of age. Additionally, the FDA has warned breastfeeding mothers not to take these medications due to the risk of serious adverse reactions in breastfed infants.

Fentanyl – Fentanyl citrate, pictured here, is a Class II controlled substance and one of the most powerful opioids on the market. It's often administered via injection or transdermal patch, or in lozenge form for pain after surgery, for difficult-to-manage chronic pain and for people who have developed a tolerance to other opioids.
The type of fentanyl usually associated with overdoses is bought on the street in powder or pill form and is often mixed with heroin in a clandestine lab to increase the high it produces. Street names include Apache, China girl, goodfella, jackpot, murder 8, TNT and Tango and Cash.

Hydrocodone – These pills are a more powerful form of codeine, called hydrocodone, and are often mixed with acetaminophen. Hydrocodone is the most frequently prescribed opioid painkiller, according to the U.S. Food and Drug Administration, and the most abused. An overdose of hydrocodone can cause "cold and clammy skin, severely constricted pupils, and slow breathing that can lead to a loss of consciousness and death."

Oxycodone – Oxycodone is a powerful narcotic pain reliever prescribed for moderate to high pain relief. It's often given in an extended-release formula for patients who will need to be on pain medications for long periods of time.
Patients are warned not to break, chew, crush or dissolve extended-release tablets because the rush of oxycodone into the system could cause serious health problems, including overdose and death.
Though highly addictive, oxycodone is not thought to be as frequently abused as hydrocodone. OxyContin, Percocet, Percodan and Tylox are some trade-name oxycodone products.
