'SHOCK' Advertising- Is this a fair comparison?

The nation's peak doctors' body has renewed its call for a ban on junk food advertising targeting the young, after research has confirmed how easily they are persuaded.

Australian Medical Association (AMA) national president Dr Andrew Pesce said the AMA has for years been calling for a ban on broadcast advertising of energy-dense and nutrient-poor foods and beverages to children, particularly in children's television viewing times.

A recent survey found one in four children were overweight or obese, while more than half indicated they had tried a new food or drink product in the past month because they had seen it advertised.

A quarter said they had eaten at a fast food outlet because it had a special offer or giveaway with a meal, while almost 20 per cent opted for a food or drink because it was linked to a movie or sports personality.

Above is an advertisement comparing drug use to eating fast food. Do you think its fair for advertising companies to use 'shock' tactics to get their point across?
