Abstract: Aspects of the invention relate to a method of controllably releasing a product to a user from a housing. The housing comprises at least one compartment, and an access opening for accessing the compartment, the access opening having a locked state and an unlocked state. The method comprises locking the access opening to the container to prevent access to the product; monitoring a measurable parameter, and comparing the measurable parameter with a threshold value; determining whether to unlock the access opening by determining whether the monitored measurable parameter meets the threshold value; and either in response to determining that the access opening should be unlocked, unlocking the access opening allowing the user to access the product located within the compartment; or in response to determining that the access opening should not be unlocked, keeping the access opening locked, preventing the user from accessing the product located within the compartment.
