<p>Climate change will affect every aspect of our <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(23)01859-7/fulltext">health and wellbeing</a>. But its potential harms go beyond the body’s ability to handle extreme heat, important as this is.</p>
<p>Extreme weather events, such as floods, droughts, storms and wildfires, are becoming more frequent and severe. These affect our <a href="https://pubmed.ncbi.nlm.nih.gov/36165756/">mental health</a> in a multitude of <a href="https://www.nature.com/articles/s41558-018-0102-4">ways</a>.</p>
<p>Coping with climate change can be overwhelming. Sometimes, the best someone can do is to seek refuge in alcohol, tobacco, over-the-counter and prescription drugs, or other psychoactive substances. This is understandable, but dangerous, and can have serious consequences.</p>
<p>We outline <a href="https://journals.sagepub.com/doi/full/10.1177/17456916221132739">five ways</a> climate change could increase the risk of harmful substance use.</p>
<h2>1. Mental health is harmed</h2>
<p>Perhaps the most obvious way climate change can be linked to harmful substance use is by damaging mental health. This <a href="https://onlinelibrary.wiley.com/doi/10.1111/dar.12448">increases the risk</a> of new or worsened substance use.</p>
<p>People with a mental disorder are <a href="https://www.hindawi.com/journals/psychiatry/2018/5697103/">at high risk</a> of also having a <a href="https://bmcpsychiatry.biomedcentral.com/articles/10.1186/1471-244X-11-25#:%7E:text=Prevalence%20of%20comorbidity%20in%20epidemiological%20studies&text=Among%20subjects%20with%20an%20alcohol,a%20comorbid%20SUD%20%5B39%5D.">substance-use disorder</a>. This often precedes their mental health problems. Climate change-related increases in the number and nature of extreme events, in turn, are escalating risks to mental health.</p>
<p>For example, extreme heat is linked to increased <a href="https://pubmed.ncbi.nlm.nih.gov/27727320/">distress</a> across the whole population. In extreme heat, more people go to the <a href="https://jamanetwork.com/journals/jamapsychiatry/fullarticle/2789481">emergency department</a> for psychiatric problems, including for <a href="https://www.sciencedirect.com/science/article/abs/pii/S0048969720338249">alcohol</a> and <a href="https://www.nature.com/articles/s43856-023-00346-1">substance use</a> generally. This is even true for <a href="https://www.sciencedirect.com/science/article/pii/S0048969720325572">a single very hot day</a>.</p>
<p>Post-traumatic stress disorder, depression, anxiety and <a href="https://onlinelibrary.wiley.com/doi/abs/10.5694/mja13.10307">other mental health</a> problems are <a href="https://www.frontiersin.org/articles/10.3389/fpubh.2019.00367/full">common</a> at the time of extreme weather events and can persist for months, even years afterwards, especially if people are exposed to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9116266/">multiple events</a>. This can <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6101235/">increase</a> the likelihood of using substances as a way to cope.</p>
<h2>2. Worry increases</h2>
<p>With <a href="https://climatecommunication.yale.edu/publications/climate-change-in-the-american-mind-beliefs-attitudes-december-2022/">increasing public awareness</a> of how climate change is endangering wellbeing, people are <a href="https://www.ons.gov.uk/peoplepopulationandcommunity/wellbeing/articles/worriesaboutclimatechangegreatbritain/septembertooctober2022#:%7E:text=The%20level%20of%20worry%20about,lives%20right%20now%20(29%25).">increasingly worried</a> about what will happen if it remains unchecked.</p>
<p>Worrying isn’t the same as meeting the criteria for a mental disorder. But <a href="https://www.undp.org/publications/peoples-climate-vote">surveys</a> show climate change generates complex emotional responses, <a href="https://www.thelancet.com/journals/lanplh/article/PIIS2542-5196(21)00278-3/fulltext">especially in children</a>. As well as feelings of worry, there is anxiety, fear, guilt, anger, grief and helplessness.</p>
<p>Some <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2904966/">emotional states</a>, such as <a href="https://www.pnas.org/doi/full/10.1073/pnas.1909888116">sadness</a>, are linked with long-term tobacco use and also make substance use <a href="https://pubmed.ncbi.nlm.nih.gov/16011392/">relapse</a> more likely.</p>
<h2>3. Physical injuries hurt us in many ways</h2>
<p>Physical injuries caused by extreme weather events – such as smoke inhalation, burns and flood-related cuts and infections – increase the risk of harmful substance use. That’s partly because they <a href="https://pubmed.ncbi.nlm.nih.gov/20033251/">increase</a> the risk of psychological distress. If injuries cause long-term illness or disability, consequent feelings of hopelessness and depression can dispose some people to self-medicate with alcohol or other drugs.</p>
<p>Substance use itself can also generate long-term physiological harm, disabilities or other chronic health problems. These are <a href="https://www.tandfonline.com/doi/abs/10.3109/00952999609001655">linked with</a> higher rates of harmful substance use.</p>
<h2>4. Our day-to-day lives change</h2>
<p>A single catastrophic event, such as a storm or flood, can devastate lives overnight and change the way we live. So, too, can the more subtle changes in climate and day-to-day weather. Both can disrupt behaviour and routines in ways that risk new or worsened substance use, for example, using stimulants to cope with fatigue.</p>
<p>Take, for example, hotter temperatures, which disrupt <a href="https://www.cell.com/one-earth/fulltext/S2590-3322(22)00209-3?_returnURL=https%3A%2F%2Flinkinghub.elsevier.com%2Fretrieve%2Fpii%2FS2590332222002093%3Fshowall%3Dtrue">sleep</a>, undermine <a href="https://jhr.uwpress.org/content/57/2/400">academic performance</a>, <a href="https://www.nature.com/articles/s41562-017-0097">reduce physical activity</a>, and promote <a href="https://www.thelancet.com/journals/lanplh/article/PIIS2542-5196(22)00173-5/fulltext">hostile language</a> and <a href="https://www.cambridge.org/core/elements/abs/climate-change-and-human-behavior/F64471FA47B8A6F5524E7DDDDE571D57">violent behaviour</a>.</p>
<h2>5. It destabilises communities</h2>
<p>Finally, climate change is destabilising the socioeconomic, natural, built and geopolitical <a href="https://www.nature.com/articles/s41558-018-0102-4">systems</a> on which human wellbeing – <a href="https://theconversation.com/climate-change-and-health-ipcc-reports-emerging-risks-emerging-consensus-24213">indeed survival</a> – depends.</p>
<p>Damaged infrastructure, agricultural losses, school closures, homelessness and displacement are significant <a href="https://www.nature.com/articles/s41558-018-0102-4">sources of psychosocial distress</a> that prompt acute (short-term) and chronic (long-term) stress responses.</p>
<p><a href="https://doi.org/10.1196/annals.1441.030">Stress</a>, in turn, can <a href="https://doi.org/10.1007/s002130100917">increase</a> the risk of <a href="https://link.springer.com/article/10.1007/s002130100917">harmful substance use</a> and make people more likely to relapse.</p>
<h2>Why are we so concerned?</h2>
<p>Substance-use disorders are economically and socially <a href="https://www.thelancet.com/journals/lanpsy/article/PIIS2215-0366(18)30337-7/fulltext">very costly</a>. Risky substance use that doesn’t meet the criteria for a formal diagnosis <a href="https://digitalcommons.fiu.edu/srhreports/health/health/32/">can also harm</a>.</p>
<p>Aside from its direct physical harm, harmful substance use disrupts <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3843305/">education</a> and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3234116/">employment</a>. It increases the risk of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6676144/">accidents</a> and <a href="https://www.tandfonline.com/doi/abs/10.1080/09595230600944479">crime</a>, and it undermines social relationships, intimate <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4795906/#:%7E:text=Results%20indicated%20that%20alcohol%20use,drinkers%20with%20low%20relationship%20satisfaction.">partnerships</a> and <a href="https://www.cambridge.org/core/journals/development-and-psychopathology/article/abs/longitudinal-relations-between-parental-drinking-problems-family-functioning-and-child-adjustment/CE508589A9E799FD6DC9E23DF364FB8F">family functioning</a>.</p>
<h2>Politicians take note</h2>
<p>As we head towards the <a href="https://www.cop28.com">COP28 global climate talks</a> in Dubai, climate change is set to hit the headlines once more. Politicians know climate change is undermining human health and wellbeing. It’s well past time to insist they act.</p>
<p>As we have seen for populations as a whole, there are multiple possible ways for climate change to cause a rise in harmful substance use. This means multidimensional <a href="https://www.nature.com/articles/s41558-018-0102-4">prevention strategies</a> are needed. As well as addressing climate change more broadly, we need strategies including:</p>
<ul>
<li>
<p>supporting vulnerable individuals, especially <a href="https://journals.sagepub.com/doi/full/10.1177/21677026211040787">young people</a>, and marginalised commmunities, who are <a href="https://www.nature.com/articles/s41558-018-0102-4">hit hardest</a> by extreme weather-related events</p>
</li>
<li>
<p>focusing health-related policies more on broadscale health promotion, for example, healthier eating, active transport and community-led mental health support</p>
</li>
<li>
<p>investing in climate-resilient infrastructure, such as heat-proofing buildings and greening cities, to prevent more of the destabilising effects and stress we know contributes to mental health problems and harmful substance use.</p>
</li>
</ul>
<p>There is now <a href="https://news.un.org/en/story/2022/10/1129912">no credible pathway</a> to avoiding dangerous climate change. However, if <a href="https://carnegieendowment.org/2023/01/12/climate-protests-tracking-growing-unrest-pub-88778#:%7E:text=These%20are%20just%20a%20few,even%20more%20numerous%20and%20influential.">increasing rates</a> of climate protests are anything to go by, the world may finally be ready for radical change – and perhaps for reduced harmful substance use.<!-- Below is The Conversation's page counter tag.
