I’ve just put a post in the Forum regarding this issue and I thought it’d be worth doing a post here too. (Please add a comment if you have any experience of this from using isopropyl nitrite).
This is what I posted in the Forum earlier.
“There was a recent study done by British scientists from the Royal Bolton Hospital with regards to Poppers use in the UK and a possible link to eye damage. As it is in the UK the poppers use they were talking about relates to the use of isopropyl nitrite as isobutyl nitrite in the UK is not freely available.
Basically the study found that use of isopropyl nitrite can in some cases cause eye damage. There is a link below to the full news story on this”.
