Abstract: Security features for an electronic metered-dose smart inhaler, mobile app, and cloud-based software system that validates users and inhaler use protocols, such as medical prescriptions and clinical trial regimens. The smart inhaler interacts with a mobile app to control and monitor per-dose usage and capture efficacy results and feedback from medical patients and clinical trial participants for review by prescribing physicians, clinical trial administrators, medicine formulators and artificial intelligence. While the smart inhaler system is well suited for aerosol medical marijuana products, it may be used to deliver and conduct clinical trials on any type of product suitable for aerosol administration including other types of medication and non-medical products, such as nicotine, herbal products, pain killers, sleep aids, dietary stimulants, dietary suppressants, etc.
