Vapor provision system

Vapor provision means for selectively generating vapors with different flavor characteristics for inhalation by a user, comprising:

• a first vapor precursor material having a first flavor characteristic;
• a second vapor precursor material having a second flavor characteristic which is different from the first flavor characteristic;
• vaporizing means for generating vapor from the first vapor precursor material and the second vapor precursor material;
• and
• control means for controlling the vaporizing means to generate vapor from the first vapor precursor material and the second vapor precursor in a ratio selected to provide vapor with a selected flavor characteristic for normal use, wherein the control means is further for determining if a user notification condition arises for the vapor provision means, and in response to determining that the user notification condition has arisen, controlling the vaporizing means to generate vapor from the first vapor precursor material and the second vapor precursor in a modified ratio to provide vapor with a modified flavor characteristic that is different from the selected flavor characteristic to provide a user with an indication the user notification condition has arisen.

A method of operating a vapor provision system configured to selectively generate vapors with different flavor characteristics for inhalation by a user by vaporizing different amounts of different vapor precursor materials having different flavor characteristics, wherein the method comprising:

• generating a vapor using a selected ratio of the different vapor precursor materials to generate a vapor with a selected flavor characteristic during normal use;
• determining that a user notification condition has arisen for the vapor provision system;
• and
• in response to determining that the user notification condition has arisen, generating a vapor using a modified ratio of the different vapor precursor materials to generate a vapor with a modified flavor characteristic to provide a user with an indication the user notification condition has arisen.
