Following raids by law enforcement in US and Canada on manufacturers, nobody now supplies the ready-made helium hood kit for self-deliverance from a terminal illness. (GLADD is gone.)
But there is now a substitute in my pamphlet “How to make your own helium hood kit” which can be downloaded as an illustrated pdf at this web site:

This is a very helpful publication. Concise and to the point. Thank you
