Can the size of products, including tobacco, affect their consumption?

shutterstock_41447758Our Cochrane systematic review has produced the most conclusive evidence to date that people consume more food and drink when offered larger-sized portions, packages or tableware, but few eligible studies were identified concerning the size of tobacco products.

We identified only three eligible studies, all examining the effect of cigarette length on consumption.A meta-analysis of these studies found low quality evidence that altering cigarette length had no impact on consumption.

However, with an absence of high-quality studies and none that manipulated the size of cigarette packs, we are unable to highlight clear implications for tobacco policy due to gaps in the current evidence base.
