You seem to be forgetting healthcare systems are built on the principle of universal care, which means treating people no matter how they got sick.
If we start drawing lines about who "deserves" treatment, where would it end? Would we refuse care to those with obesity, sports injuries, or conditions linked to diet or alcohol consumption? Almost everyone has lifestyle habits that can negatively affect health in some way.
Secondly, smoking is an addiction, not just a choice. Many smokers begin as teenagers and nicotine is notoriously hard to quit. Lots of smokers are also from disadvantaged backgrounds where there’s less access to education and support to quit. Penalising them further is harsh and counterproductive.
Many "preventable" situations are still treated as a priority for good reason. Pregnancy is technically preventable requires medical support to ensure both physical and mental health for the mother and baby.
Abortion another technically preventable scenario are vital for the physical and mental health of pregnant women in certain circumstances. Should we deny care in these cases too?
Plus education is already prioritised in healthcare. Smoking rates have declined over the years due to public health campaigns, higher taxes on cigarettes, and smoking cessation programs.
However, for those already affected, the damage can’t always be reversed, and treatment is the only option.
Everyone deserves compassion when they’re unwell, regardless of how they got there
