What does “Vaporiser” mean?

A device that heats cannabis material enough to release its active compounds as vapour without burning it.

Vaporiser in plain English

A device that heats cannabis material enough to release its active compounds as vapour without burning it.

Avoiding combustion avoids tar, carbon monoxide and other by-products that have no therapeutic purpose. It also gives more consistent delivery than smoking.

Vaporising is not harmless: airway irritation and cough are common, and running a device too hot approaches combustion. Where a prescriber specifies a device and temperature, that specification is part of the prescription.
