A one-hitter[1] (also oney, bat, tay, oney bat, or taster) is typically a slender pipe with a screened narrow bowl designed for a single inhalation, or "hit", of smoke or vapor from a small serving (about 25 mg) of heated cannabis flower, tobacco leaf or other dry, sifted herbal preparation.
[2] It is distinguished from western-style large-bowl pipes designed for strong tobaccos that are burned hot and tasted but not inhaled.
Instead, by properly distancing a lighter flame below the opening, inhalant users operate at vaporization temperatures, minimizing combustion waste and toxicity.
[7] Modern adaptations from craft-centric companies use fine and rare woods, bone, acrylic, aluminum, steel, titanium, other metals or plastics, adding features such as grinders, poker storage or lighter chambers.
Carried in a shirt pocket, they are the tangible "replacement" for a pack of cigarettes when one is eliminating a smoking habit.
