The story says she was trying to get Xanax, not Oxy.
It includes the following warning:
The potential for psychological dependence is more of a risk in individuals with a history of alcohol or drug abuse. Addiction prone individuals should be under careful surveillance when receiving Xanax. DO NOT STOP TAKING XANAX ABRUPTLY. This can cause withdrawal reactions, including seizures. Signs of withdrawal may include heightened sensory perception, impaired concentration, dysosmia (distortion of normal smell perception), clouded sensorium, parasthesias, muscle cramps, muscle twitches, diarrhea, blurred vision, appetite decreases and weight loss. Anxiety and insomnia have also been reported. Withdrawal reactions may occur when dosage reduction occurs for any reason, including forgetting to take a dose. Xanax must be reduced gradually under the doctor's supervision.
