Short for amyl nitrates, a type of alkyl nitrate.
These are commonly known as poppers
, ram, thrust, rock hard, kix and TNT.
When sniffed they provide a short-lasting head rush, similar to that of cocaine
, but which is often accompanied by the feeling that your head is being compressed from all directions.
It has also been said that they make orgasms feel like they last longer and also that they may help to relax anal muscles for use in homosexual male sex, although the latter of these is usually rejected as myth.
Poppers are not addictive, and can be bought legally as room aromas in many different brands in clubs, sex shops and smoking shops from the age of 18. They range in price from £2 - £5 per bottle.
