RULE §170.2Definitions

In this Chapter:

  (1) "Abuse" or "substance abuse"--the essential feature of substance abuse is a maladaptive pattern of substance use manifested by recurrent and significant adverse consequences related to the repeated use of substances.

  (2) "Acute pain"--the normal, predicted, physiological response to a stimulus such as trauma, disease, and operative procedures. Acute pain is time limited.

  (3) "Addiction"--a primary, chronic, neurobiological disease characterized by craving and compulsive use of drugs. Addiction is often characterized by impaired control over drug use, including taking more drugs more often than prescribed by a physician. It may also be characterized by continued use despite harm to oneself or others. Genetic, psychosocial, and environmental factors may influence the development and manifestation of addiction. Physical dependence and tolerance are normal physiological consequences of extended drug therapy for pain and, alone, do not indicate addiction.

  (4) "Chronic pain"--a state in which pain persists beyond the usual course of an acute disease or healing of an injury. Chronic pain may be associated with a chronic pathological. process that causes continuous or intermittent pain over months or years.

  (5) "Dangerous drugs"--medications defined by the Texas Dangerous Drug Act, Chapter 483, Texas Health and Safety Code. Dangerous drugs require a prescription, but are not included in the list of scheduled drugs. A dangerous drug bears the legend "Caution: federal law prohibits dispensing without a prescription" or "Prescription Only."

  (6) "Diversion"--the use of drugs by anyone other than the person for whom the drug was prescribed.

  (7) "Escalation"--increasing the dosage and/or frequency of the use of drugs.

  (8) "Pain"--An unpleasant sensory and emotional experience associated with actual or potential tissue damage or described in terms of such damage.

  (9) "Physical dependence"--A state of adaptation that is manifested by drug class-specific signs and symptoms that can be produced by abrupt cessation, rapid dose reduction, decreasing blood level of the drug, and/or administration of an antagonist. Physical dependence, alone, does not indicate addiction.

  (10) "Pseudoaddiction"--the iatrogenic syndrome resulting from the misinterpretation of relief seeking behaviors as though they are drug-seeking behaviors that are commonly seen with addiction. The relief seeking behaviors resolve upon institution of effective analgesic therapy.

  (11) "Scheduled drugs" (sometimes referred to as "Controlled Substances")--medications defined by the Texas Controlled Substances Act, Chapter 481, Texas Health and Safety Code. This Act establishes five categories, or schedules of drugs, based on risk of abuse and addiction. (Schedule I includes drugs that carry an extremely high risk of abuse and addiction and have no legitimate medical use. Schedule V includes drugs that have the lowest abuse/addiction risk).

  (12) "Tolerance" (tachyphylaxis)--a physiological state resulting from regular use of a drug in which an increased dosage is needed to produce a specific effect, or a reduced effect is observed with a constant dose over time. Tolerance does not necessarily occur during opioid treatment and does not, alone, indicate addiction.

  (13) "Withdrawal"--the physiological and mental readjustment that accompanies discontinuation of a drug for which a person has established a physical dependence.
