Rita Skeeter's Witch Weekly article states that Love Potions are banned at Hogwarts.
Love Potions are of course banned at Hogwarts, and no doubt Albus Dumbledore will want to investigate these claims. In the meantime, Harry Potter's well-wishers must hope that, next time, he bestows his heart upon a worthier candidate.
(Goblet of Fire, Chapter 27, Padfoot Returns)
Obviously Skeeter has been known to print the odd untruth in her time. I wonder if this one of them. There certainly seem to be plenty of Love Potion-brewers and -users at Hogwarts:
- Gilderoy Lockhart encourages students to ask Snape to brew a Love Potion for them.
- Molly Weasley brewed a Love Potion as a student.
- Romilda Vane repeatedly tries to dope Harry during Half-Blood Prince.
- Slughorn brews Amortentia, "the most powerful love potion in the world", in front of his sixth-year Potions class.
- The Weasley twins brew the "best range of love potions you'll find anywhere." These are banned by Filch along with the rest of the Weasleys' Wizard Wheezes products. Whether the Love Potions in that range were contraband on multiple counts is up for debate I think.
Pottermore only features this summary of the examples listed above. There's no JKR feature.
Are they actually banned? If so, why are they so commonly used with no disciplinary consequences? If not, why did Skeeter claim that they were as if it were obvious?
(Connected question. Note that I'm not asking about whether Love Potions were banned by the Ministry of Magic but whether they were banned at Hogwarts.)
