CannabisO: The Ontology-based Knowledge Model for Safe Cannabis Consumption in Thailand

In June 2022, the Ministry of Public Health of Thailand announced that cannabis can be used in healthcare, medical, research, and commerce. This announcement led to a wide discussion in social media, TV broadcasts, and public media about how to use cannabis safely, the symptoms that cannabis can relieve, side effects, and precautions of cannabis. Prior to the Ministry's announcement, cannabis was illegal and forbidden to consume since it was considered as a kind of drugs and was dangerous to consume, even privately. Most people still lack of proper knowledge about safe cannabis consumption. Also, information provided on the Internet and social media about cannabis is now often redundant, inconsistent, and unreliable. Therefore, this study gathers official and reliable published knowledge about cannabis consumption specifically for general users. CannabisO is modeled as a formal, shareable, and reusable ontology-based knowledge model to be used for a Q&A system that can help answer questions about safe edible consumption of cannabis, precautions and side effects of cannabis consumption, and lastly, symptoms that can be alleviated by cannabis. Several interesting Q&As are demonstrated in this paper.
