Long-term opioid use can cause opioid-induced hyperalgesia, which is a condition in which the patient has increased sensitivity to pain. [101] All of the opioids can cause side effects. [70] Common adverse reactions in patients taking opioids for pain relief include nausea and vomiting, drowsiness, itching, dry mouth, dizziness, and constipation.
Long-term opioid use occurs in about 4% of people following their use for trauma or surgery-related pain. [20] In the United States, most heroin users begin by using prescription opioids that may also be bought illegally. [21] [22] People with opioid use disorder are often treated with opioid replacement therapy using methadone or buprenorphine ...
In the United States, more than 12 million people use opioid drugs recreationally. [123] The U.S. Department of Health and Human Services estimates that about 11 million people in the U.S. consume oxycodone in a non-medical way annually. [124] Opioids were responsible for 49,000 of the 72,000 drug overdose deaths in the U.S. in 2017. [125]
When people continue to use opioid medications beyond what a doctor prescribes, whether to minimize pain or induce euphoric feelings, it can mark the beginning stages of an opioid addiction.

While the full synthesis of opioids from naphthoquinone (Gates synthesis) or other simple organic starting materials is possible, they are tedious and uneconomical processes. Therefore, most of the opiate-type analgesics in use today are either extracted from Papaver somniferum or synthesized from those opiates, especially thebaine. [10]
Prescription drug addiction is the chronic, repeated use of a prescription drug in ways other than prescribed for, including using someone else’s prescription. [3] [4] A prescription drug is a pharmaceutical drug that may not be dispensed without a legal medical prescription.
Non-medical use of fentanyl by individuals without opioid tolerance can be very dangerous and has resulted in numerous deaths. [166] Even those with opiate tolerances are at high risk for overdoses. Like all opioids, the effects of fentanyl can be reversed with naloxone, or other opiate antagonists. Naloxone is increasingly available to the public.
