Smoking and HIV

smoking

If you have HIV, are on treatment and smoke, your risk of death is doubled.

Cigarettes contain over 4,000 chemicals, around 50 of which cause cancer. These include carbon monoxide, which reduces the oxygen levels in your blood so that not enough oxygen is delivered to the organs and your energy levels drop.

Smokers become addicted to the nicotine in cigarettes, which is why you experience cravings and withdrawal symptoms when you stop smoking.

Smoking affects your blood pressure, fertility, your skin, teeth and lungs, and increases your risk of cancer, heart disease and stroke.

Does smoking cause worse problems for people with HIV?

Yes. According to a recent study, if you have HIV, are on treatment and smoke, your risk of death is doubled.

On the other hand, non smokers with HIV who are doing well on treatment can expect to have a normal lifespan. You can read more about the study here.

Another study from Denmark has recently reported that the rate of heart attacks among smokers with HIV is three times higher than that of HIV negative smokers. You can read more about the study on Aidsmap.

Smoking rates are higher among people living with HIV. HIV itself causes changes to the cholesterol, which can cause or hasten cardiovascular disease. In addition, certain antiretrovirals also have a negative effect on cholesterol and lipids. If you add smoking to the mix, the risks are greater.

These findings show how important it is to try to stop smoking so that you have as good a chance as possible of leading a normal lifespan. It can be difficult to stop but there is lots of free help and support.

Are you more likely to smoke if you have HIV?

New American research, published in AIDS, has found that rates of ‘modifiable risks of cancer’ were higher in HIV positive people.

Modifiable risks are factors over which we have some control, such as:

  • smoking,
  • drinking,
  • infection with HPV and
  • hepatitis B and C.

The study found that in people living with HIV, these modifiable risks occur at higher rates than in the general population. As much as 54% of the HIV positive participants included in the study were smokers – a proportion around two-and-a-half times higher than in the general American population.

How can I stop smoking?

Some people use nicotine replacement products to help them stop. These can come in the form of patches, lozenges, gum, inhalers and inhalators and you can gradually reduce the amount you take until the cravings pass.

Your doctor can prescribe you nicotine replacement therapy. There are also medicines you can take to help with your cravings - one of these is called varenicline (Champix). A recent French study into smoking cessation among HIV positive people found that it had a much higher success rate than a placebo in helping people to stop. However, less than 20 per cent of study participants were able to stop smoking for more than a year and Champix can have side effects such as depression. Read more about this study.

Every area has a local NHS service to help you stop smoking. As well as nicotine replacement therapy, they also provide group or one-to-one support. There is also a national helpline. You can find out more at Smoke Free.

Should I try vaping?

e-cigarettes: many people have found using e-cigarettes (vaping) helps them quit smoking. Although e-cigarettes can contain nicotine, which is addictive, they don’t contain all the toxins found in cigarette smoke that cause cancer and heart disease.

The NHS advises that e-cigarettes are less bad for you than smoking cigarettes but points out that there is still debate about whether or not the chemicals in e-cigarettes are bad for you. At the moment there hasn’t been a large-scale study into their effects. You can read more here.

Extra support with quitting:

Smokefree is an NHS website with lots of advice and information about quitting.

You can call their helpline on: 0300 123 1044. It is open from Monday to Friday from 9am to 8pm, Saturday and Sunday from 11am to 4pm.

You can also chat to one of their advisers online.
