A dry-powder inhaler (DPI) is a device that delivers medication to the lungs in the form of a dry powder. DPIs are commonly used to treat respiratory diseases such as asthma, bronchitis, emphysema and COPD although DPIs (such as inhalable insulin) have also been used in the treatment of diabetes mellitus.

A wide range of volatile solvents intended for household or industrial use are inhaled as recreational drugs. This includes petroleum products (gasoline and kerosene), toluene (used in paint thinner, permanent markers, contact cement and model glue), and acetone (used in nail polish remover). These solvents vaporize at room temperature.
Toluene is widely used in the paint, dye, rubber, chemical, glue, printing, and pharmaceutical industries as a solvent. [38] Nail polish, paintbrush cleaners, and stain removers may contain toluene. Manufacturing of explosives (TNT) uses it as well. Toluene is also found in cigarette smoke and car exhaust.
Six positional isomers are possible for dinitrotoluene. The most common one is 2,4-dinitrotoluene. The nitration of toluene gives sequentially mononitrotoluene, DNT, and finally TNT. 2,4-DNT is the principal product from dinitration, the other main product being about 30% 1,3-DN2-T.
An inhaler (puffer, asthma pump or allergy spray) is a medical device used for delivering medicines into the lungs through the work of a person's breathing. This allows medicines to be delivered to and absorbed in the lungs, which provides the ability for targeted medical treatment to this specific region of the body, as well as a reduction in the side effects of oral medications.
The Philadelphia Eagles weren't in top form, but the NFC's No. 2 seed had enough to handle the Green Bay Packers for a wild-card playoff win.
It is mainly used to manufacture toluene diisocyanate, which is a key raw material in polyurethane chemistry. [4] It is still the starting material used when non-phosgene methods of production of toluene diisocyanate are used. [5] [6] It is also a degradation product of polyurethane materials produced using toluene diisocyanate.
Some of the largest volcanic eruptions on the planet have occurred at Yellowstone National Park, and scientists have determined when the next one could occur.
