Researchers used 2022–23 survey data from people aged 12–34 who had used nicotine, tobacco or cannabis in the past month. On average, users said they had used about two different products in that time.
The team found six main groups of users. The biggest group used combustible (smoked) tobacco. Other groups included people who vape nicotine and people who used cannabis edibles. The study notes that smoked products are usually more harmful and that using many product types can make quitting more difficult.
