Clara originally obtained a prescription sedative to manage occasional panic during turbulent flights. Over the past year, however, she has started taking it every afternoon before her corporate team meetings. To achieve the same level of calm and anxiety relief that she experienced initially, she now must ingest four times her original dose.
On days when she attempts to go without the sedative, Clara experiences intense physical sweating, severe hand tremors, and rapid heart rate. Furthermore, she has developed a deep-seated belief that she cannot deliver her presentations or communicate effectively with her department head unless she has taken the medication.
Discuss concepts of substance dependence with reference to Clara's behaviour.
