Embodiments of the invention provide systems and methods to provide safe, secure and accurate point-to-point delivery of prescription and non-prescription drugs in the long-term home care or ambulatory care environment. More specifically, embodiments of the present invention provide for a low-cost, easy-to-use system comprised of a secure drug dispensing unit and medication enclosure combined with wireless connectivity and software based on smart mobile phone technology. Such systems and methods, referred to herein as a Secure, Control, and Enhance Medication Adherence (SCEMA) system, can mitigate the aforementioned risks associated with the use of prescription and non-prescription drugs. These risks can be significantly reduced for the elderly in the homecare environment, as well as the general public, without disrupting, or a significantly increasing the cost, to the existing prescription and non-prescription drug distribution infrastructure. In addition, the SCEMA system can provide a powerful platform for drug research.
