Impairment in short-term memory and lingering deficit in psychomotor performance are but two of the acute cannabis intoxication components that may have long-term consequences. The former because it affects learning and the latter because it interferes with proper handling of motor vehicles. The most frequently observed complication of cannabis inebriation, however, is a short-lasting acute psychological disturbance with symptoms of panic, paranoid apprehension and personality disorganization. This type of reaction is often not dose-related, and could appropriately be termed "pathological intoxication". In addition to the acute effects of cannabis on mental performance and behaviour, this paper reviews the psychiatric consequences of chronic use and the accumulated evidence on organic toxicity associated with it: residual cognitive deficit, lethargic symptoms, cannabis psychosis, respiratory, gastro-intestinal and cardiovascular complications, as well as effects on immune response and gonadal functions, are discussed. Also included are reviews on the pharmacology and therapeutic potential of cannabinoids.

A fatal case of poisoning by a mixture of methanol and ethylene glycol is described. A 72-year-old man was hospitalized when he was found stuporous to semicomatose, and despite massive bicarbonate therapy, died 36 hr after the admission. While the presence of numerous oxalate crystals in urine strongly suggested ethylene glycol intoxication, the GC analysis of the liquid the patient ingested revealed that he presumably drunk about 150 to 200 ml of a mixture of methanol (80%) and ethylene glycol (20%), the amount well over the lowest lethal dose when the additiveness of toxicity was considered. Retrospective evaluation of the signs suggested that while some of them such as oxalate crystalluria, elevated CPK, hypocalcemia, renal failure are attributable to the toxicity of ethylene glycol, others including elevated serum amylase and cyanosis are indicative of methanol poisoning. Disturbed consciousness was considered to be of metabolic origin; the high anion gap observed (38.2 mEq/liter) may be due not only to lactic acidosis but also to acidogenicity of the two chemicals ingested. The importance of gas chromatographic analysis for identification of the causative chemical(s) is stressed.

A 21-day-old boy presented to our emergency department hypotonic, lethargic, and intermittently unresponsive to pain. A workup for ketoacidosis, sepsis, and central nervous system hemorrhage was negative. A urine drug screen collected eight hours after hospitalization showed 39 mg/dl of isopropyl alcohol and 76 mg/dl of acetone. The first serum drug analysis was not performed until 18 hours after admission, at a time when there had been clinical improvement. The isopropyl alcohol concentration was 8 mg/dl, and the acetone concentration was 203 mg/dl. Management was supportive, and the patient stabilized. He was discharged from the hospital in good health in three days. A further review of the history showed no evidence for an oral exposure to isopropyl alcohol. However, since leaving the maternity hospital the mother had been applying gauze pads or cotton balls soaked with isopropyl alcohol to the umbilicus with every diaper change. We conclude that the child suffered from an isopropyl alcohol intoxication that occurred by absorption through the umbilical area.

Isopropyl alcohol continues to be a frequent toxicologic exposure. However, no cases involving the newborn period have been described. A 14-day-old male infant presented to the emergency department (ED) with the mother's chief complaint that "He is not himself." Physical examination observed the infant to be lethargic and hypotonic. Laboratory evaluation revealed a positive urine drug screen for isopropanol and acetone. Elevated serum levels (in mg/dl) of isopropanol/acetone at 2:45, 4:15, 11:10, and 29:53 hours postpresentation were 101/136, 81/149, 20/155, and 5/72, respectively. Overall, this patient did remarkably well with minimal supportive care and was noted to have a normal neurologic examination within 10 hours of presentation despite rising serum acetone levels. This case brings into question the hypothesis that acetone, a metabolite of isopropanol, prolongs central nervous system depression in acute isopropyl alcohol intoxication. The importance of urine drug screens in children who present to the ED with unusual neurologic examinations is appreciated.
