popper I imagine you mean the little bottle that you sniff.
I have no idea what would hapen if you did take this stuff my mouth . I only thought you inhaled it.
The affects when inhaled are somawhat the same as to the affects of acid or E, but a tad more intense .
My advise ...dont swallow it, not inhale it .
After inhaling you will have loads of green snot for days and not feel like yourself .
In saying that ..If you do take it ..I have heard it kill a shot load for brain cells per second .
If your dumb enough to take it after that ...well ..your gona be dumber afterwards .
.".more intense than acid or e..."????...blimey where do you buy yours from?... it's completley legal, you can buy it mostly in sex shops, spent most of the 80s with a bottle stuck to my nose..
