Similarity is based on note and accord overlap, not molecular analysis.
Differences come from accords and community votes on longevity and sillage.
The main accords of Opium Pour Homme Eau de Parfum are powdery and soft spicy. It opens with Black Currant and Star Anise, reveals Sichuan Pepper and Galanga at its heart, and dries down to Bourbon Vanilla and Tolu Balsam. It lasts very long and projects strongly; people reach for it in autumn and winter, mostly in the evening.
