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 ...
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 ).
The user puts their mouth at the top and places the cannabis in the tube, as shown in the picture. Bongs are often either glass or plastic that use a bowl, stem, and water to produce smoke. Most glass bongs are made from heat resistant borosilicate glass, allowing the bong to withstand repeated use and heat exposure without breaking.
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 ]
The plethysmography technique applies Boyle's law and uses measurements of volume and pressure changes to determine total lung volume, assuming temperature is constant. [8] There are four lung volumes and four lung capacities. A lung's capacity consists of two or more lung volumes.
Here are some key words used throughout the article. The process of forcing air into and out of the lungs is known as ventilation. The process by which oxygen is taken in by the bloodstream is called oxygenation. Lung compliance is the capacity of the lungs to contract and expand.
TLC: Total lung capacity: the volume in the lungs at maximal inflation, the sum of VC and RV. TV: Tidal volume: that volume of air moved into or out of the lungs in 1 breath (TV indicates a subdivision of the lung; when tidal volume is precisely measured, as in gas exchange calculation, the symbol TV or V T is used.)
