More & more states are legalizing adult use of marijuana and a wave of technology is spreading throughout the industry, including specialized cannabis software and technology for more efficient grow operations, as well as existing tech that can be tailored to the industry. Guardian Data Systems is just one example of marijuana technology growth. Guardian began as a service to buy medical marijuana from dispensaries online using a credit card — a novelty in a mostly cash-only industry. The system enables pre-approved customers with state-licensed dispensaries to use their credit cards to pay for product online and receive it via home delivery in states where it’s legal to do so, like Oregon and Nevada. Guardian’s tech offerings have transformed into a complete enterprise software solution for cannabis businesses, including point-of-sale and distribution software, automated inventory and delivery options, and more. MassRoots and Leafly provide information like THC and CBD levels, aroma and flavor in a plethora of cannabis strains. Artificial intelligence. PotBotics, uses a recommendation engine (read: AI) that takes plant DNA analysis and other cannabis research to guide medical marijuana patients to tailored treatment with appropriate strains and products. The software can even make appointments for patients with licensed medical cannabis clinics nearby, and also some in a mobile app called PotBot.
