The law of contract is used by the court as an instrument for discouraging misleading and extravagant claims in advertising and for deterring the marketing of unproven, and perhaps dangerous pharmaceuticals...

But in the Pall Mall Gazette (just one instance where he put ads) there were many, many more quack remedies for misunderstood problems.

The Pharmaceutical Society of Great Britain had been fighting an ongoing battle against quack remedies, and had wanted specifically to get carbolic acid on the poisons register since 1882. Although without sympathy for the Carbolic Smoke Ball Company itself, Simpson casts doubt on whether Carlill was rightly decided. "The analytical problems arose in a particularly acute form in the smoke ball case. Thus it seemed very peculiar to say that there had been any sort of agreement between Mrs. Carlill and the company,
