The analysis of a survey of adults in Great Britain found that 5% of self-identified non-smokers are past year cannabis users with an estimated 380,000 smoking cannabis with or without tobacco at least weekly.
A further 830,000 tobacco smokers also smoke cannabis at least weekly meaning that there may be around 1.2 million at least weekly cannabis smokers in Great Britain. Long term smokers of cannabis have an increased risk of many of the same diseases that tobacco smokers do. Furthermore those who mix cannabis with tobacco are at risk of establishing a tobacco addiction which can be very difficult to break.
Hannah Walsh from the Florence Nightingale Faculty of Nursing, Midwifery & Palliative care at King’s College London and one of the study’s authors said the findings raised concerns that non-smokers were unaware that smoking cannabis carries similar health risks to tobacco.
It is extremely concerning that there are hundreds of thousands of people who do not see themselves as ‘smokers’ but are none-the-less smoking every week. It is possible that they do not realise they are putting their health at risk. It’s also a concern that people may be unwittingly establishing a tobacco addiction as a consequence of their cannabis use.– Hannah Walsh, Faculty of Nursing, Midwifery & Palliative care, King’s College London
The study found that cannabis was disproportionately used among younger people with 70% of people who had used cannabis in the last year being under 39. It also found that those who reported using cannabis and tobacco together were more likely to report mental health problems than those who used either product on its own.
In the UK, in common with other parts of Europe, cannabis is usually consumed by smoking it with tobacco. In other parts of the world, particularly the Americas, while cannabis is still usually smoked, it is much less common to smoke cannabis combined with tobacco.
Government generally sees cannabis and tobacco as separate issues but plainly their use is deeply interwoven in our country. There is an opportunity to address this in the Government’s planned Addiction Strategy and Tobacco Control Plan. This strategy must include measures to tackle the overlapping use of cannabis and tobacco and the resulting harm to health.– Hazel Cheeseman, Director of Policy at Action on Smoking and Health
