How long after quitting smoking does erectile dysfunction improve?

If you smoke or vape and have noticed changes in your erections, you're not imagining things. Smoking and nicotine can directly affect your ability to get and maintain an erection by damaging blood vessels and restricting blood flow to the penis.

How long after quitting smoking does erectile dysfunction (ED) improve? The answer may surprise you: Research shows measurable changes in penile blood flow within 24–36 hours of quitting. 

The timeline for nicotine erectile dysfunction recovery varies from person to person, but improvements can start sooner than many people expect.

The changes can start quickly. Studies have found measurable improvements in penile blood flow within 24–36 hours of quitting smoking.

Circulation continues to improve over the following weeks and months. By six months, a review identified that more than 50% of people with ED who quit reported improvements. This is roughly double the rate of those who tried to quit but couldn't.

Many quitters also saw gains in sexual satisfaction, orgasmic function, and desire.

At the one-year mark, research found that some people who quit saw continued improvement in ED, while none of those who kept smoking did.

That said, the exact timeline depends on several factors, including how long and how heavily a person smoked, their age, and their overall cardiovascular health. 

People with more advanced ED or those who are older may see slower or less complete improvement, but quitting at any stage can still help.

Personalized ED treatment for you.

Get started

Yes, smoking can cause erectile dysfunction. ED from smoking is primarily a vascular issue: Getting an erection depends on healthy blood flow to the penis, and smoking undermines that process in a few key ways.

The chemicals in cigarette smoke damage blood vessel walls over time, making them narrower and less flexible. Smoking also interferes with nitric oxide, the chemical your body uses to signal blood vessels in the penis to relax and widen.

On top of that, it contributes to atherosclerosis — plaque buildup in the arteries — which further restricts circulation.

The more you've smoked, the bigger the impact tends to be. One study specifically found a significant association between pack-years (packs per day multiplied by years of smoking) and the severity of ED.

Nicotine is likely part of what links smoking to ED, though it may not be the only factor. Cigarettes contain thousands of chemical compounds, and research hasn't fully established which ones are most responsible for ED. 

What is known is that nicotine narrows your blood vessels, which can reduce the blood flow needed for erections. Over time, it may also promote calcification within blood vessel walls, making them stiffer and less able to function properly.

However, some studies have found that erectile function continued to improve even when patients were still receiving nicotine through patches, suggesting that other components of cigarette smoke also play a role.

This matters because many people assume switching to nicotine replacement therapy (NRT) or e-cigarettes eliminates the risk. NRT products can still be a valuable part of a quitting plan, and they're safer than continuing to smoke. 

But it's worth knowing that nicotine, regardless of how it's delivered, has vascular effects that may influence erectile function.

Vaping can contribute to erectile dysfunction, and this is an area of growing concern. A large study found that daily e-cigarette users were more than twice as likely to experience ED compared to people who had never vaped. This association held even after adjusting for other risk factors.

If you're wondering, "If I stop vaping, will my ED go away?" there's good reason for optimism, though research is lacking on the topic. 

Since vaping affects the vascular system in similar ways to traditional cigarettes — in part through nicotine's effects on blood vessels — removing that exposure may allow blood vessels to begin recovering. However, long-term research specific to vaping cessation and ED is still limited. 

As with traditional cigarettes, nicotine is likely not the only factor, but reducing exposure may still support better blood flow to the penis.

Quitting smoking can offer sexual benefits beyond improving ED. For example, it can also help blood vessels begin to heal, which can promote improved circulation throughout the body over time, including to the penis. Better blood flow could translate to improved exercise tolerance, which may mean better stamina during sex.

One study of people aged 30–60 who quit found improvements in sexual desire, orgasmic function, and overall satisfaction — not just ED.

For some people, quitting smoking may not completely resolve ED — particularly if the damage to blood vessels has been significant and if other contributing factors are involved.

If that's the case, there are several effective treatment options to discuss with a healthcare provider:

Lifestyle changes

Healthy habits can further support erectile function alongside quitting smoking:

• Regular exercise: Physical activity improves cardiovascular health and blood flow, both of which are important for erections.

• Balanced diet: A diet rich in fruits, vegetables, whole grains, and lean proteins supports heart and vascular health.

• Limit alcohol intake: Excessive alcohol consumption can contribute to ED. Moderating intake may help.

• Manage stress: Stress and anxiety can contribute to ED. Approaches like cognitive behavioral therapy (CBT), sex therapy, or counseling may help alleviate any mental challenges. And research suggests they can be even more effective when combined with medical treatment.

Medications

PDE5 inhibitors are commonly prescribed to enhance blood flow to the penis and help with erections if they’re medically appropriate for your individual needs. They’re prescription medications that include: 

• sildenafil (Viagra)

• tadalafil (Cialis)

• vardenafil (formerly available as Levitra)

• avanafil (Stendra)

Dosage should be discussed with your healthcare provider and not something you should handle on your own.

Ro also offers two unique treatment options:

• Ro Sparks*, a fast-acting, two-in-one option containing sildenafil and tadalafil that dissolves under your tongue. Once dissolved, it can start to work in just 15 minutes and last up to 36 hours. 

• Daily Rise Gummies*, daily tadalafil gummies that work continuously, no planning or timing required.

*Though this particular formulation isn’t US Food and Drug Administration (FDA)-approved, it is composed of active ingredients that have been individually FDA-approved for ED.

Other treatment options

If other approaches haven't been enough, there are additional options a healthcare provider may suggest.

• Testosterone replacement therapy: If a healthcare provider diagnoses you with low testosterone and believes it’s contributing to ED, a healthcare provider may recommend hormone therapy.

• Vacuum devices: These create a vacuum to draw blood into the penis, and a constriction band is placed at the base to maintain the erection.

• Penile implants: In cases where other treatments haven't worked or aren’t preferred, surgical implants may be considered.

The decision about which treatment is right for you should be made with a healthcare provider, who can evaluate your specific situation and health history.

Quitting smoking is one of the most impactful things you can do for your erectile health and your overall wellbeing. Here are some evidence-based approaches to help you get started:

• Set a quit date: Choose a specific day to stop and use the lead-up to prepare mentally.

• Consider NRT: Patches, gum, lozenges, and nasal sprays can help manage cravings and withdrawal. NRT is considered safer than continuing to smoke, even though nicotine itself has vascular effects.

• Ask about prescription options: Bupropion and varenicline are non-nicotine medications that reduce cravings and can make quitting easier. Both require a prescription.

• Get support: Working with a healthcare provider, counselor, or support group can significantly improve your chances of quitting for good.

• Know your triggers: Pay attention to what makes you reach for a cigarette or vape, and have a go-to alternative ready — a short walk, a glass of water, or a few deep breaths.
