Device to vaporize substances for inhalation A vaporization heat wand and vaporization chamber bowl used to deliver vapor through a water pipe A vaporizer or vaporiser, colloquially known as a vape, is a device used to vaporize substances for inhalation. Plant substances can be used ...
The dry-bulb temperature (DBT) is the temperature of air measured by a thermometer freely exposed to the air, but shielded from radiation. [1] The dry-bulb temperature is the temperature that is usually thought of as air temperature, and it is the true thermodynamic temperature. It is directly proportional to the mean kinetic energy of the air ...
3,3′-Diaminobenzidine (DAB) is an organic compound with the formula (C 6 H 3 (NH 2) 2) 2. This derivative of benzidine is a precursor to polybenzimidazole, which forms fibers that are renowned for their chemical and thermal stability. [1] As its water-soluble tetrahydrochloride, DAB has been used in immunohistochemical staining of nucleic ...
Spotting cannabis oil or resin is thought to be particularly harmful to the lungs, as the smoke comes off the oil at such a high temperature. [10] One possible way of minimizing the risks of spotting marijuana is using cooler knives, leading to the tetrahydrocannabinol (THC) being vaporised rather than the entire plant matter being burnt.

The particles in tobacco smoke are liquid aerosol droplets (about 20% water), with a mass median aerodynamic diameter (MMAD) that is submicrometer (and thus, fairly "lung-respirable" by humans). The droplets are present in high concentrations (some estimates are as high as 10 10 droplets per cm 3 ).
Ventilation is normally unconscious and automatic, but can be overridden by conscious alternative patterns. [3] Thus the emotions can cause yawning, laughing, sighing (etc.), social communication causes speech, song and whistling, while entirely voluntary overrides are used to blow out candles, and breath holding (for instance, to swim underwater).

In medicine, a nebulizer (American English) [1] or nebuliser (British English) [2] is a drug delivery device used to administer medication in the form of a mist inhaled into the lungs. Nebulizers are commonly used for the treatment of asthma , cystic fibrosis , COPD and other respiratory diseases or disorders.
