Generic opioids have the potential to be as dangerous as they are effective. It has recently been revealed that several drug companies actively hid this information from the public, and the first criminal charges have now been filed against some former drug executives. However, the dangers of opioids remain the same. If taken over a period of time, opioids could trigger dependence. Even weaning dependency could cause serious problems, and full abstention may cause symptoms of withdrawal such as anxiety, depression, muscle cramping, nausea, vomiting, and diarrhea.
