A curious new meme has roared across global social feeds, and Thai teens are riding the wave. The “6-7” trend began with a December 2024 rap track and exploded onto TikTok and Instagram in early 2025, with millions of short videos echoing the same four syllables. What started as a cryptic line tied to a Chicago street has become a lighthearted, ubiquitous catchphrase that adolescents use in a variety of playful, sometimes nonsensical contexts. A leading commentator on trends in youth culture notes that the phrase now means whatever the user wants it to mean, underscoring a fundamental truth of memes: meaning evolves as it spreads. In short, 6-7 shows how a single line can transform into a social phenomenon simply through automated re-creations, remixes, and the attention of highly connected online communities.

A recent US case highlights how vaping can pose serious, even life-threatening, health risks. A 39-year-old New York woman, who switched from smoking to vaping, was hospitalized with severe lung failure within a year. Her experience mirrors a broader pattern found in new research on e-cigarettes, a habit adopted by many in Thailand and around the world.

The patient, a long-time smoker who started vaping after quitting cigarettes, developed acute lung complications. She could not lie flat or perform basic tasks, and doctors diagnosed pulmonary bullae—damaged lung tissue that creates large air spaces. Vaping had to stop immediately, and surgery was urgent. She described vaping as “100 percent more dangerous than cigarettes,” warning others about dangers she never anticipated. Experts say this case reflects a common misunderstanding that vaping is a safe alternative, a belief that shapes behaviors and policy.

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.
