Smoking substitute device

1. A system for managing a smoking substitute device, the system comprising:

a smoking substitute device comprising:

a control unit; and

an interface configured to communicate with an external device,

wherein the control unit is configured to, after a predetermined action is performed using the smoking substitute device, disable the smoking substitute device when a predetermined criteria relating to usage of the smoking substitute device is met and/or a predetermined length of time has elapsed; and

an external device, configured to, when a user of the smoking substitute device has passed an age verification test, send a signal indicating that the age verification test has been passed by the user of the smoking substitute device via the interface of the smoking substitute device;

wherein the control unit is configured to enable the smoking substitute device when a signal indicating that an age verification test has been passed by a user of the smoking substitute device is received by the smoking substitute device via the interface;

wherein the control unit and/or the external device is configured to:

monitor the usage of the smoking substitute device and derive a usage profile associated with the user of the smoking substitute device; and

monitor for deviation from the usage profile, wherein the predetermined criteria relating to usage is met when a deviation from the usage profile meets a predetermined threshold.

2. The system of claim 1 , wherein disabling the smoking substitute device includes disabling a heater of the smoking substitute device.

3. The system of claim 1 , wherein the interface is a wireless interface, which is configured to communicate wirelessly with the external device, and wherein the signal indicating that an age verification test has been passed by the user of the smoking substitute device is received via the wireless interface.

4. The system of claim 1 , wherein the predetermined action is any one or more of:

a first activation of the smoking substitute device, triggered by the user inhaling from the smoking substitute device;

a first activation of the smoking substitute device, triggered by the user turning the smoking substitute device on;

a first activation of the smoking substitute device, triggered by the user connecting the smoking substitute device to a charger;

a first connection of the smoking substitute device to the external device;

removal of a tab within the smoking substitute device; and

a first connection of a consumable suitable for use with the smoking substitute device to the smoking substitute device.

5. The system of claim 1 , wherein the predetermined criteria relating to usage is any one or more of:

a number of activations of the smoking substitute device;

a number of coil activations of the smoking substitute device;

an accumulated time over which the smoking substitute device has been activated;

a number of power charging cycles of the smoking substitute device; and

an amount of power consumed by the smoking substitute device.

6. The system of claim 1 , wherein the predetermined time is any one of:

1 week or less;

48 hours or less; or

24 hours or less.

7. The system of claim 1 , wherein the control unit is configured, after a previous age verification test has been passed by the user, to disable the smoking substitute device when a further predetermined criteria relating to usage of the smoking substitute device is met, and to enable the smoking substitute device when a subsequent age verification test has been passed by the user.

8. The system of claim 1 , wherein the control unit is further configured to, after the user has performed the predetermined action using the smoking substitute device, avoid disabling the smoking substitute device when the predetermined criteria relating to usage of the smoking substitute device is met, if the signal indicating that an age verification test has been passed by a user of the smoking substitute is received by the smoking substitute device before the predetermined criteria relating to usage of the smoking substitute device is met and/or the predetermined length of time has elapsed.

9. The system of claim 1 , wherein the external device is a mobile device.

10. The system of claim 1 , wherein the external device is a remote server.

11. The system of claim 1 , wherein the system is configured to, in response to the smoking substitute device becoming disabled pending an age verification test, provide the user with the age verification test in which a determination is made as to whether the user has a predetermined age or higher.

12. The system of claim 1 , wherein verifying that the user is of a predetermined age or higher includes:

requesting and receiving information from the user indicative of the user's age; and

crosschecking the requested information with an external database.

13. The system of claim 1 , wherein the system includes a remote server, and the remote server is configured to disable the smoking substitute device if it is determined that a number of devices registered to a same user exceeds a threshold.

14. The system of claim 1 , the system further comprising:

a remote server; and

wherein the remote server is configured to disable the smoking substitute device if it is determined that a number of devices registered to a same user exceeds a threshold.

15. The system of claim 14 , wherein the smoking substitute device comprises:

a control unit; and

an interface configured to communicate with an external device;

wherein the control unit is configured to, after a predetermined action is performed using the smoking substitute device, disable the smoking substitute device when a predetermined criteria relating to usage of the smoking substitute device is met and/or a predetermined length of time has elapsed; and

wherein the control unit is configured to enable the smoking substitute device when a signal indicating that an age verification test has been passed by a user of the smoking substitute device is received by the smoking substitute device via the interface.

16. The system of claim 1 , wherein the control unit is configured to allow at least a first activation of the device, without requiring an age verification test to be performed.
