Consider the following medical report that includes the patient's historical health records. Use it to predict the disease that the patient is high likely exposed to. 

 Medical Report: history of present illness: this is a 26 year old male with no past medical history who was found unresponsive in a parked running car. there was no trauma or evidence of motor vehicle accident. the second passenger was found in the same condition. he was in respiratory distress but able to saturate 15% on 15 liters face mask. he was unable to be intubated secondary to a straight type of clenched jaw. blood glucose at the scene was 137. he was given narcan and versed without response and brought to the . in the emergency department, his pupils were pin point. he was intubated and cord temperature was noted to be 91 degrees. he was given a bear hugger and warm saline. blood pressure was 110/60. electrocardiogram showed sinus bradycardia with a prolonged q-t approximately 500 milliseconds. he was suspected to be a ghb overdose and toxicology screen was positive for cocaine, amphetamines and benzodiazepines. chest x-ray showed an aspiration pneumonia versus pneumonitis and he was given a dose of clindamycin and ceftriaxone. while in the emergency department, he self extubated and was initially kept on oxygen, however, secondary to continued vomiting and inability to protect his airway, he was reintubated and brought to the medical intensive care unit. physical examination: on examination, temperature was 101.2, pulse 99 and regular, blood pressure 142/65, oxygen saturation 100% on ventilator. head, eyes, ears, nose and throat - the pupils are 3.0 millimeters bilaterally and reactive. the neck was supple. lungs revealed coarse anterior breath sounds. heart was regular rate and rhythm, normal s1 and s2, no murmurs. the abdomen was soft, nontender, nondistended, with normoactive bowel sounds. extremities showed no edema. multiple tatoos, warm and dry. no damage. gcs was 3.0 and sedated. laboratory data: white blood cell count 12.5, normal differential, hematocrit 41.6, platelet count 243,000. coagulation studies within normal limits. chem7 was within normal limits. carboxyhemoglobin was 0.3. lactate was 2.6. urine toxicology was positive for benzodiazepines, cocaine and amphetamines. electrocardiogram showed sinus bradycardia at 53 beats per minute, normal axis, q-tc of 500 milliseconds but no st elevations or depressions. chest x-ray showed a left middle lobe opacity and head ct was negative for hemorrhage. hospital course: the patient was brought to the medical intensive care unit for further monitoring after his overdose. a toxicology consultation was obtained in the emergency department and was felt most likely to be a polypharmacy overdose including ghb. given supportive care overnight on the ventilator and kept sedated on propofol. the following morning he was able to take deep total breath and after lightening the sedation he was extubated. at that time, he admitted to cocaine, alcohol and ghb overdose. he had one history of a similar overdose approximately six years ago. an electrocardiogram was rechecked and showed normalization of the q-t interval. given that he was afebrile, no productive sputum, no cough, and chest x-ray showed resolution of the left upper lobe opacity, it was felt most likely aspiration pneumonitis as opposed to pneumonia. he showed no evidence of infection and antibiotics were discontinued. on hospital day, after being observed for an additional 24 hours after extubation with normal hemodynamics and respiratory function, he was discharged to home. he was given the number for clinic for follow-up and to start counseling about the dangers of further overdose. condition on discharge: good. discharge status: to home. discharge diagnoses: 1. acute respiratory failure. 2. overdose. 3. aspiration pneumonitis. medications on discharge:: none. follow-up: given the telephone number for clinic to follow-up with primary care physician. , m.d. dictated by: medquist36 procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours insertion of endotracheal tube diagnoses: alcohol abuse, unspecified cocaine abuse, unspecified acute respiratory failure pneumonitis due to inhalation of food or vomitus amphetamine or related acting sympathomimetic abuse, unspecified toxic effect of unspecified alcohol poisoning by other specified drugs and medicinal substances, undetermined whether accidentally or purposely inflicted 

Answer: The patient is high likely exposed to
