And can one actually become addicted to "room fragrance" sniffing? This handbook answers all these questions, clarifies the different types of poppers, warns of dangers and interactions with other substances, provides tips for responsible use, explains whether and how to make it oneself, and identifies the cheapest sources. The book features insights from doctors, pharmacists, and sex researchers, as well as openly discussing gay celebrities who talk about it candidly and without taboos.
