The invention relates to a device (10) for adjusting an amount of an active substance inhaled by a user, which comprises: two vessels (105, 110), a first vessel (105) comprising a liquid having a lower density of active substance than a liquid in the second vessel (110), each liquid being configured such as to evaporate when said liquid is heated beyond a predetermined temperature limit; a means (115) for inhalation, by the user, of the liquid vapour evaporating from each vessel; two heating resistors (120, 125), each vessel being associated with one heating resistor; a means (130) for determining an amount of active substance to be vaporised; a means (135) for controlling the heating of each resistor in order to actuate each resistor independently in accordance with the determined amount of active substance to be vaporised, the ratio of the heating of the resistor associated with the second vessel to the heating of the resistor associated with the first vessel being an increasing function of the determined amount of active substance to be vaporised. |
