Secure storage of controlled substances

A secure electronic enclosure comprising:

• a main body having an access door hingedly connected thereto, whereby said access door in movable between an open configuration and a closed configuration;
• an electro-mechanical access control system adapted to automatically lock said access door when configured from the open configuration to the closed configuration;
• said electro-mechanical access control system including a battery power source;
• said electro-mechanical access control system including at least one electric motor mechanically connected to drive a worm gear that moves a deadbolt from an extended position to a retracted position;
• a deadbolt return spring forced into compression upon retraction of said deadbolt;
• a pin and at least one door latch compression spring, said door latch compression spring forced into compression when said door is disposed in the closed configuration;
• wherein said deadbolt engages said pin when said access door is in the closed configuration thereby locking said access door;
• and
• wherein retraction of said deadbolt frees said pin whereby said at least one door latch compression spring causes said access door to spring open;
• wherein said deadbolt return spring returns said deadbolt to said extended position;
• and
• a current supervisory circuit which monitors said battery power source, said supervisory circuit generating a low battery notification when the battery power source reaches a first reference threshold, and upon reaching a second reference threshold said current supervisory circuit retracts said deadbolt causing said door to spring open.
