The members of the most fascinating subset of the vaping community call themselves Cloud Chasers. They hack vapes in order to create the biggest cloud of vapour possible. Simultaneously competitive and collaborative, they have developed their own language, rituals, and rules of conduct. They push their devices to the limit, explore techniques and tricks, and exchange advice and knowledge across all platforms, whether online or in real life. These photos explore their pride and obsession. One moment of glory, a fleeting masterpiece immortalised on film, contrasting with long hours spent researching, testing and practising.
