The more I dig, the more crazy information I find...
Here's a drug addict forum... Sick... but sometimes, once you start it barrels out of control.
"Then there are the modern narcosis inhalants like isoflurane, sevoflurane etc. which are used for operations today. You probably won't be able to get your hands on those, and they are very expensive.
There's the first medical inhalant ever: chloroform. I inhaled this myself a few times many years back, even made it myself via haloform reaction.
It's quite potent, 2-3ml is enough for a strong buzz.
It is known to be hepatotoxic and carcinogenic, but it can't be that bad since I did not suffer any adverse symptoms other than a little nausea after a longer session. I think the dangers are exaggerated, as it is in fashion today for so many chemicals.
Educate yourself about the history of chloroform as an inhalant, it's interesting."

I just dont think that she would be thinking Chloroform to kill her daughter! She's smarter than we think in some areas, but I dont think she is smart enough to come up with that.
I have a feeling that these new friends, (as I believe Ryan described them as a new crowd for CAM) all liked to party. A lot of teens-twenty somethings try drugs. Sometimes it gets out of hand. Some HS friends I had were trying whippets (Nitrous Oxide). At first, I think they were amused how it just made them laugh. I did not participate in this, I like beer and wine. Anyhow, it indeed got out of hand, with that and pot. The same boys got caught vandalizing a public building, and later in the year, one of them commited suicide. None of us will ever understand why, even 18 years later!
