The Impact of Cannabis on Thai Public Health
The Evolving Landscape of Cannabis in Thailand: Public Health Implications
The legalization of cannabis in Thailand in 2022 marked a significant shift in the country’s approach to this substance, transitioning from a strictly prohibited narcotic to a legally accessible product for both medical and recreational use. This change has brought about a myriad of public health implications that are crucial to understand and address.
Historical Context and Legalization
Prior to 2019, cannabis was classified as a class-5 narcotic under Thailand’s Narcotic Act, prohibiting its use, possession, and sale. However, with the growing momentum of the pro-cannabis movement, Thailand legalized medical cannabis in 2019, allowing individuals 20 years and older to register for medical cannabis treatment without fear of criminal prosecution.
The removal of cannabis from the class-5 narcotic list in June 2022 further liberalized its use, making Thailand the first Asian country to permit the sales, growing, possession, and recreational use of cannabis plants without legal penalty.
Health Risks Associated with Cannabis Use
The legalization of cannabis has raised several public health concerns. One of the significant risks is the increased likelihood of traffic accidents. Studies have shown that cannabis use can significantly impair driving performance, and in Thailand, where the legal driving age is 15 for motorcycles and 18 for cars, this is a particular concern. Unlike in some Western countries, Thailand lacks specific laws and data on cannabis-impaired driving, highlighting the need for surveillance and research in this area.
Cannabis use is also linked to various health issues, including psychiatric problems, road accidents, and economic losses. A study involving 261 cannabis users in Kalasin province found that these users made 2,698 visits to healthcare facilities in a year, with 150 visits due to cannabis-related illnesses. Additionally, 150 users reported psychiatric problems, and 14 users were involved in road accidents.
Tuberculosis Risk and Cannabis Use
A recent study conducted in Songkhla Province revealed a concerning association between cannabis use and the risk of active pulmonary tuberculosis (TB). The study found that sharing a bong of cannabis significantly increased the risk of TB, with an odds ratio of 4.22. This is particularly alarming in a country where TB is already highly prevalent, with an incidence rate of 143 per 100,000 individuals in 2021.
Impact on Youth
The lack of regulation following legalization has raised concerns about the accessibility of cannabis to youth. Studies in the US have shown that while state-based legalization did not increase cannabis use among youth, the normalization of cannabis use and increased potency of cannabis products could lead to higher rates of cannabis dependence and psychiatric disorders among young users. In Thailand, there is a need for public health-oriented regulation to prevent underage access and mitigate these risks.
Medical Cannabis and Quality of Life
Despite the risks, cannabis has shown potential in improving the quality of life for certain patient groups. A prospective observational cohort study across 30 sites in 21 Thai provinces examined the use of “Ganja Oil,” a cannabis extract, in treating symptoms like pain, anorexia, and insomnia. The study found significant improvements in quality of life for both cancer and non-cancer patients using this treatment.
However, the integration of traditional cannabis applications into regulated healthcare systems remains challenging. The absence of standardized prescribing protocols and comprehensive national studies post-legalization underscores the need for rigorous research to inform clinical practice.
Economic and Social Impacts
The economic and social impacts of cannabis use are also noteworthy. A study in Kalasin province found that cannabis users incurred significant medical costs and economic losses due to law enforcement and other indirect costs. The total medical costs for the cannabis users amounted to 142,560 baht (approximately 4,537 USD), with an average of 3,168 baht (approximately 101 USD) per case.
Public Health Strategies and Recommendations
Given the complex public health implications of cannabis legalization, several strategies are recommended:
- Regulation and Surveillance: Implementing public health-oriented regulations, such as taxation, limitations on youth-focused marketing, and restrictions on public consumption, is crucial. Surveillance and research on cannabis-impaired driving and other health risks are also essential.
- Standardized Prescribing Protocols: Developing standardized prescribing protocols for medical cannabis to ensure safe and effective patient care is vital. This includes merging traditional practices with evidence-based medicine.
- Public Education: A national cannabis-related prevention program should be implemented to improve community knowledge of cannabis risks and delay initiation among youth.
- Healthcare Access: Ensuring that healthcare providers are equipped with the necessary guidelines and resources to manage cannabis-related health issues is important. For example, the Department of Medical Services’ official “Guidelines on Medical Cannabis” should be widely adopted.
Conclusion and Future Directions
The impact of cannabis on Thai public health is multifaceted and requires careful monitoring and evaluation. While cannabis offers potential medical benefits, it also poses significant health risks, particularly among vulnerable populations such as youth and those with lower socioeconomic status.
To navigate these challenges, Thailand must adopt a comprehensive public health approach that includes robust regulation, surveillance, and education. By learning from experiences in Western countries and conducting rigorous local research, Thailand can develop evidence-based guidelines to inform prevention strategies and ensure the safe and effective use of cannabis.
