Dozens of opiates and related drugs (sometimes called opioids) have been extracted from the seeds of the opium poppy or synthesized in laboratories. The poppy seed contains morphine and codeine, among other drugs. Synthetic derivatives include hydrocodone (Vicodin), oxycodone (Percodan, OxyContin), hydromorphone (Dilaudid), and heroin (diacetylmorphine). Some synthetic opiates or opioids with a different chemical structure but similar effects on the body and brain are propoxyphene (Darvon), meperidine (Demerol), and methadone. Physicians use many of these drugs to treat pain.

Opiates suppress pain, reduce anxiety, and at sufficiently high doses produce euphoria. Most can be taken by mouth, smoked, or snorted, although addicts often prefer intravenous injection, which gives the strongest, quickest pleasure. The use of intravenous needles can lead to infectious disease, and an overdose, especially taken intravenously, often causes respiratory arrest and death.

The CDC’s Guideline on Prescribing Opioids for Chronic Pain helps doctors and patients manage treatment at safe levels and avoid dependence. Any plan to taper medication dosage should be personalized to the patient’s needs.

Q. With the holidays coming, I may be tempted to drink more than usual — maybe enough to have a hangover the next morning. I'm wondering if a hangover could actually damage my brain.

A. There have been a few scientific studies of that question. Recently, a team of scientists examined those existing studies, involving over 1,100 people, and came to some tentative conclusions, published online August 25 by the journal Addiction.
