The effort has been categorized as a Health Alert Network Advisory signaled to a multitude of professionals within the health field. The advisory explains four key action points. Those points include the (a) local need to expand the distribution and use of naloxone and overdose prevention education, (b) expand awareness, access, and availability of treatment for substance use disorders, (c) intervene early with individuals at highest risk for overdose, and (d) improve detection of overdose outbreaks to facilitate more effective response.Another initiative is a social media campaign from the United States Drug Enforcement Administration (DEA) called "One Pill Can Kill". This social media campaigns goal was to spread awareness of the prevalence of counterfeit pills that are being sold in America that is leading to the large overdose epidemic in America. This campaign also shows the difference between counterfeit pills and real pills. This campaign also offers resources for help with drug addiction and rehabilitation.In New Jersey another initiative was started called "The Partnership for a Drug-Free New Jersey" (PDFNJ) was created to inform the people of New Jersey the harm of taking drugs and where to dispose of expired or unneeded prescription medications. Some of this programs campaigns also focus on children and teaching children how to deal with the influence and peer pressures of these drugs. Pharmacology
Classification
Fentanyl is a synthetic opioid in the phenylpiperidine family, which includes sufentanil, alfentanil, remifentanil, and carfentanil. Some fentanyl analogues such as carfentanil are up to 10,000 times stronger than morphine. Structure-activity
The structures of opioids share many similarities.
Alcohol use during pregnancy was previously listed as a risk factor, but is discredited by this article. Classification
Traditionally, four grades of placenta previa were used, but it is now more common to simply differentiate between "major" and "minor cases. Other than that placenta previa can be also classified as:
Complete: When the placenta completely covers the cervix
Partial: When the placenta partially covers the cervix
Marginal: When the placenta ends near the edge of the cervix, about 2 cm from the internal cervical os

Diagnosis
History may reveal antepartum hemorrhage. Abdominal examination usually finds the uterus non-tender, soft and relaxed. Leopolds maneuvers may find the fetus in an oblique or breech position or lying transverse as a result of the abnormal position of the placenta. Malpresentation is found in about 35% cases. Vaginal examination is avoided in known cases of placenta previa. Confirmatory
Previa can be confirmed with an ultrasound. Transvaginal ultrasound has superior accuracy as compared to transabdominal one, thus allowing measurement of distance between placenta and cervical os. This has rendered traditional classification of placenta previa obsolete.False positives may be due to following reasons:
Overfilled bladder compressing lower uterine segment
Myometrial contraction simulating placental tissue in abnormally low location
Early pregnancy low position, which in third trimester may be entirely normal due to differential growth of the uterus.In such cases, repeat scanning is done after an interval of 15–30 minutes. In parts of the world where ultrasound is unavailable, it is not uncommon to confirm the diagnosis with an examination in the surgical theatre.
