Cas94, tried to send you a reply, but it wouldn't go through. (this system,God)
Anyway I wanted to apologize for jumping on your case. I didn't check your profile first and just assumed you were some dumb kid looking for his next high or how to off himself easily. Sorry bout that.
Glad to hear you had a legitimate question, looking for a serious answer, and not what I thought it was.
Never heard of that before for staying warm, but it makes sense as long as you don't inhale the fumes. Hope you never need to use it for obvious reasons.
Take care, and thanks for the clarification. I will sleep much better tonight knowing you are not trying to harm yourself or get high.(LOL at me!)
