Amyl nitrite is the chemical compound with the formula C5H11ONO. First produced in 1857 as a treatment for angina, amyl nitrite evaporates at room temperature. The vapor released causes your veins and arteries to dilate resulting in the blood flowing faster through the heart and the brain. It came in a sealed bulb, about 3 times bigger than a cod liver oil tablet. When the bulb was broken, it maid a popping sound; hence the name “poppers“. Before 1979, it was available without a prescription. Older gay men will tell you tell you, if you ask them nicely, that since then what is being sold as poppers is not is not as effective. Since the law changed many companies sell other nitrites as “room aromas”. If you’re lucky probably, butyl nitrite or isobutyl nitrite, but, it is never clear which nitrite exactly they are selling. Nitrates are extremely corrosive and you should never drink or eat it as it can burn and severely damage the skin. Mixing this with a drink or combination of other drugs can be dangerous. Mixing with any erection-inducing drugs, including Viagra (sildenafil), Cialis (tadalafil) and Levitra tablets (vardenafil) can be very dangerous if you are using nitrates as it causes your blood pressure to drop.I’m often asked my men coming for a massage if it’s ok for them to use poppers. I always tell them it’s absolutely fine, but that they could get the same effect by doing simple breathing exercises.
