What is an inhalant that smells like pvc glue, makes you high for over 4 hours?

one of my friends has a friend that inhaled some vapors/fumes from a small blue bottle. He said it smelled like pvc glue. He mentioned that the high lasted for about 4 hours and that he felt as though he was "rolling" and it gave him a strong libido. He doesn't think its spanish fly or an amyl nitrate. What could it be?

It is most likely TCE or Trichloroethylene. This causes a sense of euphoria and smells like PVC glue because it is a main ingredient in the glue. After more study I have also learned that it has about a 3-5 hour duration of effect. However, that is it's half life and it is not fully out of the system for up to 10 hours.

The bottle that it came in could be a variety of bottles used by distributors and can not definitively point to any specific substance. (Although it could point to a specific dealer)

EDIT: I am sure that you know this but I have to say it. Inhalants are deadly.

22% of people who die from inhalant use are first time users!

55% of deaths linked to inhalant abuse are caused by 鈥淪udden Sniffing Death Syndrome.鈥?SSDS can occur on the first use or any use.

If you do not die right away, likely you will suffer permenant brain damage. Just keep an eye on your friend and you will see the effects. Memory loss, loss of cognitive function and likely more. Stay away at all costs.
