Addiction to ether consumption, or etheromania, is the addiction to the inhalation or drinking of diethyl ether, commonly called "ether". Studies, including that of an ether addict in 2003, have shown that ether causes addiction; however, the only symptom observed was a will to consume more ether. No withdrawal symptoms were prevalent.

During the second half of the 19th century, ether was in vogue as a recreational drug in some places, becoming especially popular in Ireland, as Irish temperance campaigners thought it was an acceptable alternative to alcohol.

Addiction to ether consumption had posed a serious social problem in Poland during the Interwar period. The drinking of ether, as well as related liquids (Hoffman's drops) was commonplace and widespread foremost in the region of Upper Silesia. According to surveys conducted in the 1930s, in certain villages a large portion of pupils of public schools had regularly drunk ether. Teachers had recalled that at certain times they had to send home pupils who were under the influence of the drug. Common drinking of ether by mine workers caused a ban on access by intoxicated persons to the mines (the main cause for concern was the risk of fire). Plant doctors had received a stark warning to drastically limit the purchases of ether and its mixtures for factory doctors' offices. The Catholic Church was engaged in fighting this addiction; it was often the topic of sermons, certain priests refused absolution to the addicted, and even reported their parishioners to the police. The consumption of ether was also spread in the regions of Suwałki, south-eastern Poland, the Beskidy mountains, Kujawy, Pomerania and around Częstochowa.

Smuggling across the German and Czechoslovak borders was the primary source of ether, with local authorities estimating thousands of kilograms were smuggled yearly. Ether was mainly smuggled by inhabitants of border regions, who sometimes used specially trained dogs. Both people and dogs smuggled ether in protruding metal containers which lay very close to the body and were attached to it with straps (termed blachany, from the Polish word blacha meaning "steel sheets", from which they were made). Sometimes special compartments in cars were used, and attempts recorded include transporting ether via cable cars stretched across a border river.^{[citation needed]}

Ether was distributed among the villages by wagons transporting straw, as well as by travelling salesmen, organ grinders, and beggars. Within the villages themselves, ether was distributed in designated places, termed kapliczki ("chapels" in Polish). These were places both of sale and consumption. Many accidents caused by improper handling of fire were recorded at such places. Through the early 21st century ether has seen a strong resurgence amongst teenagers in India.

Drinking ether is challenging as it boils below body temperature and is not miscible with water, requiring precautions:

There is an art in swallowing the ether. The drinker first washes out his mouth with water “to cool it;” next he swallows a little water to cool his throat; then he tosses down the glass of ether; finally, he closes in with another draught of water to keep the ether from rising, or, in other words, to cool his stomach, so that the volatile ether may not be lost by eructation of its vapour. In a little time the "trick” is easily acquired by members of both sexes.

Another recorded means of consumption was by inhalation of vapor, which develops at room temperature due to ether's volatility. The risks to the gastric system inherent in imbibing ether are avoided by using inhalation, and the effects are significantly shorter lasting.^{[citation needed]}
