Shisha bars: BGN has determined minimum ventilation requirements
Glowing coals from shishas produce carbon monoxide. The gas is odourless and highly toxic.

The consequences are headaches, dizziness, nausea and respiratory paralysis, as well as damage to unborn babies. But even below these acute effects, it can cause long-term damage to health.
