Poppers are also known as: amyl/butyl/isobutyl nitrite, amyl (especially in Australia, where it's promounced 'ammul'), aromas and by brand names like Liquid Gold, Rush, etc. They're often (but wrongly) called 'nitrates', which is a similar, but different chemical.
Poppers are a liquid made from chemicals from the alkyl nitrite family. The name comes from the days when they came in glass capsules that popped when broken open.
Poppers can make you feel horny, lower your inhibitions and make orgasms feel stronger. Because they relax the sphincter (the muscle in the arse hole) poppers can make it easier to be fucked or fisted. They can cause a man to lose his hard-on too.
Research shows poppers might play an important role in HIV being passed on. The reasons could be:
It's thought the biggest risk of HIV being passed on is when an HIV negative man uses poppers when fucked without a condom by a man with HIV.
When dancing or having sex the fumes are breathed in, usually through the nose (or inhaled through the mouth or from a poppers-soaked cloth). They should never be swallowed as this can stop the heart and kill.
Seconds after breathing them in, poppers cause a rush of blood to your head, your heart beats fast and muscles relax (including the sphincter muscle in your arse hole). For a few minutes you can feel an excited, light-headed feeling. They can be used on the dancefloor too, to boost the effects of music and lights.
Headache is the main side effect. Poppers on the skin causes poppers burns which go in a few days (wash poppers of with water straight away but get medical help if they get in your eyes).
In some people poppers cause dizziness or fainting.
Poppers aren't addictive in the way some drugs are but they can be habit-forming and the more you use them the less effect they have. Sensitivity comes back after a few days of not using them.
Viagra-type drugs - makers of erection drugs like Viagra warn against using them with poppers, as both lower blood pressure. Poppers are nitrites. A similar drug (nitrates) is used by people with heart problems. Taking Viagra, etc. while on nitrates has killed people by causing a fatal drop in blood pressure. So to be on the safe side, caution is advise with poppers (nitrites) too.
HIV drugs - protease inhibitors push up levels of erection drugs in the body, meaning a bigger risk of a dangerous interaction if poppers are used.
Ecstasy, speed, cocaine or crystal meth - these all put strain on the heart. Taking them with poppers stresses it even more.
Because poppers can kill an erection, it's better to put a condom on before the first hit of poppers.
Poppers easily catch fire so should be kept away from naked flames, cigarettes, etc.
You should avoid poppers if you've got high or low blood pressure, a heart condition or glaucoma (an eye condition)
Possessing poppers is not illegal under UK law. The reason poppers are sold as a 'room deodoriser', 'leather cleaner' or 'tape head cleaner' is to get round restrictions against selling them as a product to be breathed in.
