The controversy behind the company emerged as a result of the drugs that they made and how they carried high potential for addiction. The most commonly abused medications that the company produces are MS Contin and OxyContin. Both can be abused by crushing, chewing, snorting, or injecting the dissolved product. These ingestion methods create a significant risk to the abuser; they can result in overdose and death. Drug-seeking tactics that addicts undergo to obtain the medication include "doctor shopping", which is visiting a number of different physicians to obtain additional prescriptions and refusal to follow up with appropriate examinations. Along with the high potential for abuse among people without prescriptions, there is also a risk for physical dependency and reduced reaction or drug desensitization for patients that are prescribed them. Nevertheless, strong analgesic drugs remain indispensable to patients suffering from severe acute and cancer pain.
