Daily cannabis use may increase the risk of erectile dysfunction (ED), according to several studies. Research suggests THC can affect blood vessels, testosterone levels, and nervous system signals involved in achieving and maintaining an erection. However, effects vary from person to person, and factors like frequency, dosage, and overall health play a role.
If you're noticing changes in sexual performance, it's worth understanding the cause. Cannabis use is just one possible factor—others include stress, cardiovascular health, hormones, and medications. A free, instant, online symptom check can help you evaluate your symptoms privately, identify possible causes, and guide your next steps—whether that's a lifestyle change or a conversation with a doctor.

Research indicates that smoking weed every day might be connected with erectile dysfunction (ED) in some men. Studies have found that frequent cannabis use could interfere with hormonal balance, blood flow, and nerve function, all of which are important for achieving and maintaining an erection.
One systematic review and meta-analysis noted a potential relationship between cannabis use and the risk of ED, while a long-term clinical experience study also observed similar impacts on male sexual function. However, it's important to remember that not every man who uses cannabis daily will develop ED. Individual factors like overall health, frequency and amount of cannabis use, as well as genetic predispositions, play a role in how cannabis may affect sexual health.
If you're experiencing ED and use cannabis daily, take Ubie's free AI symptom checker to better understand what might be affecting your sexual health. This can help you identify possible causes and prepare for a more informed conversation with a healthcare provider, who can guide you toward solutions tailored to your situation and suggest effective strategies for managing both cannabis use and any sexual health concerns.
