#Marijuana

A wave of new research is drawing unprecedented connections between marijuana use and serious cardiovascular risks, overturning widely-held beliefs that cannabis is relatively harmless. Large-scale studies published in mid-2025 point to a significantly increased risk of heart attack, stroke, and cardiovascular death among users of marijuana—a finding that experts caution should inform personal and public health choices in Thailand and worldwide (The New York Times; Fox News; Virgin Islands Consortium).

As marijuana use undergoes rapid normalization, with legal medical and recreational access expanding across the world, researchers warn that its cardiac dangers are becoming clearer and more urgent. In Thailand, where medicinal cannabis was legalized in 2022 and recreational use remains in legal limbo, these findings arrive as lawmakers and public health officials debate the way forward in marijuana regulation and education (CNN).

New research released in 2025 strengthens concerns about marijuana’s impact on heart health. Large-scale studies show cannabis users face higher risks of heart attack, stroke, and cardiovascular death compared with non-users. These findings arrive as Thailand debates cannabis regulation and public health messaging amid growing access to medical cannabis and ongoing questions about recreational use.

Recent analyses indicate that marijuana’s active compounds, especially THC, can affect blood vessels, heart rate, and blood pressure. In Thailand, where medicinal cannabis was legalized in 2022 and recreational use remains unresolved, experts say the new evidence underscores the need for careful policy making and consumer education. Public health officials note that the tone of messaging around cannabis—often framed as “natural medicine”—must now include clear information about cardiovascular risks.
