Poppers are a type of inhaled drug which is made up of various alkyl nitrites. Poppers have not been legal in the US since they were banned in 1990. Studies show that these drugs when inhaled are actually less dangerous when compared to other drugs. If they are swallowed or aspirated then they could be deadly. There are still some countries where poppers are legal, and are sold in bars and clubs
. as well as sex shops. They are also sold over the internet and shipped all over the world. Since most places make it illegal to buy/sell poppers for human consumption they are often marketed as polish, head cleaners, or room deodorizers. The attempts to make poppers illegal even under the other names were not successful. Since these substances do have other uses the blanket ban on them was quashed. Instead there are warning labels on such cleaners that inform people of the risks of ingesting them.
