Opium poisoning in modern times. An overview

Opium is a substance extracted from Papaver somniferum L that is chronically abused specially in the traditional production regions. Reports on opium poisoning has largely disappeared from the occidental literature on drug problems but recent scientific articles show cases of death related to opium in industrialized countries. This fact led us to consider the interest of knowing the state of the art of acute opium intoxication in modern times. This work shows a compilation of these uncommon cases occurred in different settings and circumstances. Data were obtained by a computer assisted search of the literature using the key words “opium poisoning”, “poppy”, “poppy seeds”, and “papaver somniferum” in PubMed, accompanied by a hand search of the reference lists of all articles for any relevant studies not included in the database. In addition, Google Scholar, government reports, and cases adequately documented on websites were reviewed.Type 1 cases, Accidental opium intoxications when it is used as a recreational drug: Reported cases came mainly from industrialized countries. They were mostly male with a range age of 17–64 years. Many had antecedents of alcoholism or drug abuse and opium tea was used as a substitute of heroin. Rachacha has caused poisonings in France and has been detected in a stash in Spain. Toxicological analysis was documented in forensic cases. The danger of this renewed interest in opium is exemplified in that many of the poisoning cases resulted in fatalities. Type 2 cases, Accidental opium intoxications in children or adults when it used as folk remedy: Pediatric intoxication after the use of opium as folk remedy are mainly published in traditional opium-producing areas with a long history of use or ethnic communities in England or USA.

Type 4 cases: Accidental opium intoxications when using the abdominal or pelvic cavity for concealing the drug: Accidental opium body packer intoxications are seen in patients who traveled from illegal opium areas of production. Type 5 cases: Suicides by opium: Opium was a prevalent agent among cases of suicides in Iran but data are scarce.
