| Summary: | Introduction
The capability of a commercial waterpipe electric heater to simulate
the waterpipe charcoal heating system using waterpipe tobacco consumption
as a metric was evaluated, and a research-grade waterpipe electric heater to
standardize waterpipe tobacco emission testing was designed.
Methods
The experiment was conducted in two phases. In Phase 1, tobacco
was heated using either charcoal or a commercial electric heater. The tobacco
temperature was recorded during a 57-minute machine-smoking session and
tobacco consumption was measured. In Phase 2, a similar procedure was followed
using a novel research-grade electric heater.
Results
In Phase 1, tobacco consumption using either charcoal or the commercial
electric heater averaged 31.35% and 20.56%, respectively. In Phase 2, tobacco
consumption using the research-grade electric heater, set at target temperatures
of 470, 430, 400, 380, 370 and 350°C, averaged 55.74, 41.22, 40.18, 39.10, 31.57
and 26.14%, respectively.
Conclusions
The commercial electric heater did not reach consumption levels seen
in the charcoal heating system, whereas the research-grade electric heater did and
can be used as part of a standardize waterpipe tobacco emission testing regimen.
