Puffpaw, a blockchain-integrated vape pen that rewards users with tokens for reducing their usage, has been criticized by a UK addiction treatment center. The center argues that the gamification and crypto rewards of Puffpaw may actually worsen users' addictions and encourage non-smokers to take up vaping. It also raises concerns that Puffpaw may attract traditional smokers to switch to vaping instead. The health risks of vaping are also highlighted, with studies showing that e-cigarettes contain and emit toxic substances. However, the UK's National Health Service views vaping as a less harmful alternative to smoking. Another study suggests that young people who use e-cigarettes are more likely to start smoking traditional cigarettes later on.
