Johnpaul began using nicotine pouches to help him get off vapes – but says it just led to another addiction.
At one stage he was using 15 pouches a day, although the 16-year-old has now cut back to five.
Health experts say the pouches – small sachets that fit between the top lip and the gum, nicknamed "snus" by some teenagers - are addictive and may have other harmful side effects.
They are largely unregulated in the UK and there is currently no law to stop children buying them.
Some campaigners fear that the ban on disposable vapes which comes into effect on 1 June could see more young people turning to the stronger nicotine pouches.
