A grandmother’s Facebook post highlighting the cost of cigarettes compared to a food shop has gone viral.

On Saturday, Judy Lawson shared a photograph of a packet of cigarettes alongside a full food shop comprising meat, fruit, vegetables and cereal among other staples.

At $56.85 AUD (£29.48), the food shop costs almost exactly the same as a packet of 40 cigarettes, which costs $56.95 AUD (£29.53).
