A new wave of scientific concern is cresting over cannabis use, as recent research finds that using marijuana—whether smoked or eaten in gummies—is directly associated with significant risks to heart health. The findings, published in JAMA Cardiology and led by researchers at the University of California, San Francisco (UCSF), upend the common belief that cannabis is a safer or even harmless alternative to tobacco, particularly as legalization and recreational use continue to rise worldwide, including in Thailand.

A new study raises serious concerns about cannabis and heart health. Research led by investigators at UCSF and published in JAMA Cardiology shows that cannabis use—whether smoked or consumed as edibles—may impair cardiovascular function. The findings challenge the idea that cannabis is a safer alternative to tobacco, especially as legalization and consumer use expand globally, including in Thailand.

For Thai readers, the study arrives at a moment when policy, health messaging, and potential economic benefits of cannabis are hotly debated. Thailand has moved to legalize certain cannabis activities, creating a local landscape where public health guidance needs to keep pace with evolving regulations. The new evidence underscores the importance of clear information for patients, clinicians, and regulators.

A wave of recent studies is drawing global attention to a striking trend: the tetrahydrocannabinol (THC) content in cannabis – the primary compound responsible for the drug’s psychoactive “high” – is now far more potent than in previous decades. According to new data reported by Axios, the average THC level in U.S. cannabis has quadrupled since the 1990s, signaling both significant changes for cannabis users and new health concerns for society at large Axios. For Thai readers—whether policymakers, healthcare providers, students, or parents—the global surge in high-potency cannabis raises important questions about public health, legal approaches, and cultural attitudes toward marijuana.

New data shows that cannabis today is far more potent than in the 1990s. The average THC level in cannabis has quadrupled over the past few decades, raising concerns about health risks and how societies regulate the drug. For Thai policymakers, healthcare professionals, students, and parents, this global trend prompts questions about public health, law, and cultural attitudes toward cannabis.

In the 1990s, cannabis with around 5% THC was among the strongest options available. By 2025, many cannabis products—flowers, concentrates, and edibles—often contain 20–30% THC, with some extracts even higher. The rise is driven by advanced cultivation, selective breeding, and growing demand for stronger effects. This escalation comes with increased potential for adverse effects, particularly for new users and young people.
