Abstract: The present invention provides an amorphous solid for use in aerosol generation, the amorphous solid comprising: about 1 to about 50 wt % cannabidiolic acid (CBDA); about 10 to about 80 wt % aerosol-former material; gelling agent; and optionally filler, wherein the amount of gelling agent and optional filler taken together is from about to about 60 wt %; wherein the wt % values are calculated on a dry weight basis.

Abstract: An electronic aerosol provision system, comprising an air pathway between an air inlet and an air outlet; and a vaporiser for generating vapour into the air pathway; wherein the air pathway between the air inlet and the vaporiser is configured to support laminar airflow.

Abstract: A vaping monitor system comprises an electronic vapor provision system (EVPS) operable to generate vapor from a payload in response to an inhalation by a user, and to supply inhalation data to a dosage processor that is operable to calculate an amount of an active ingredient delivered to the user's bloodstream based on pharmacokinetic data for the EVPS and the inhalation data, the dosage processor also being operable to convert the calculated amount of an active ingredient into an equivalent number of a reference conventional combustion product based on pharmacokinetic data for the reference conventional combustion product, and the vaping monitor system being operable to indicate the equivalent number of a reference conventional combustion product via a user interface.
