Discussing toxicity without reference to dose is misleading; pure butane is inherently non-toxic. While butane isn’t metabolized in the human body, continuous exposure to high levels can penetrate the circulatory system, potentially altering regular metabolic functions.
When butane is inhaled, it travels to the lungs where it’s absorbed and then impacts the brain, suppressing the central nervous system. Minor exposure may cause symptoms like dizziness, headaches, and blurred vision. In contrast, significant exposure can lead to unconsciousness.
