Diethyl ether, or simply ether, is an organic compound with the chemical formula (CH 3 CH 2) 2 O, sometimes abbreviated as Et 2 O. [ a ] It is a colourless, highly volatile , sweet-smelling ("ethereal odour"), extremely flammable liquid .
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 dependence ; however, the only symptom observed was a will to consume more ether.
It also maintains List I of chemicals and List II of chemicals, which contain chemicals that are used to manufacture the controlled substances/illicit drugs. The list is designated within the Controlled Substances Act [ 1 ] but can be modified by the U.S. Attorney General as illegal manufacturing practices change.

Diethyl ether has a long history as a medical anesthetic; when starting fluid was mostly ether, a similar effect could be obtained using it. Use at the present time directly as an inhalant includes the effect of the petroleum solvents, which are more toxic as inhalants than diethyl ether. [7] [8]
On 30 September 1846, Morton administered diethyl ether to Eben Frost, a music teacher from Boston, for a dental extraction. Two weeks later, Morton became the first to publicly demonstrate the use of diethyl ether as a general anesthetic at Massachusetts General Hospital, in what is known today as the Ether Dome. [105]
When one substance dissolves into another, a solution is formed. A solution is a homogeneous mixture consisting of a solute dissolved into a solvent. The solute is the substance that is being dissolved, while the solvent is the dissolving medium. Solutions can be formed with many different types and forms of solutes and solvents.
