---------- ***New Sections (8 February 2004)*** ----------

DXM Medical Journal Articles These are scientific writings about DXM that appeared in peer reviewed medical literature. None involve deaths, but are of interest to those curious about the scientific writings regarding this drug.

DXM Deaths Currently in this section is the 1988 Rammer article about 2 DXM deaths in Sweden, and the 1970 Rivers article about the death of a woman who took some DXM containing cough syrup while also taking the prescription MAOI antidepressant Nardil.

Extraction of dextromethorphan hydrobromide from Coricidin HBP Cough & Cold. Revised 5 June, 2002.

Agent Lemon technique for extracting DXM from Robitussin cough syrup. Usable for versions of Robitussin cough syrup (and also generic versions of Robitussin cough syrup) containing just DXM, or DXM + guaifenesin. CAUTION: This extraction is NOT safe to use with versions of Robitussin cough syrup, or Robitussin cough syrup generics that contain other active ingredients like pseudoephedrine or acetaminophen other than dextromethorphan.

Coricidin Deadly Warning. YES, This is a DANGEROUS way to take dextromethorphan, because of the added anticholinergic drug in Coricidin HBP Cough & Cold!

Old issues of the DXM Zine, edited by Gravol. NOTE: Much of this material about dextromethorphan (Coricidin, Robitussin cough syrup, etc.) is outdated, and some is seriously inaccurate. We make this available for historical purposes only, and assume no responsibility for the content. YOU HAVE BEEN WARNED! Later issues of the DXM Zine can be found at "The Dextroverse".

DXM Patent - Read the actual US patent. (And, a thank you to gravol for supplying these.)

DXM Music - Currently contains a MP3 of "Piss Factory" by Patti Smith. (WARNING: sexually explicit lyrics)

Some MP3 files I like, including Janis Ian MP3s. (These have nothing to do with DXM; this section is just a personal indulgence.)
