Does laser therapy help people quit smoking?

01

Keep the older review—and its cutoff—visible

Cochrane's 2014 acupuncture-related review searched in 2013. Its two laser trials were inconsistent and could not be pooled; its conclusions did not establish consistent sustained benefit. Those were the laser trials in that review, not the number of studies available today.

A 2021 review searching to March 2021 reported a favourable long-term laser-versus-sham result from two trials with 160 participants, rating that comparison moderate-certainty. That positive finding should not be erased. It is still a specific, small comparison, not proof of every commercial protocol or an individual's permanent quitting. Different reviews cannot be read as one continuous update without comparing their inclusion and outcome definitions.

A 2025 publication can still contain older trials

The laser-auricular review published on 14 October 2025 reports a search covering 2000–2021 and selected four trials. Its pooled dependence-score result favoured laser, but the reported differences in continued smoking immediately and at three months were not statistically significant. A lower questionnaire score is not the same outcome as cigarette abstinence.

The authors describe potential benefit and reported safety, while warning about limited trials and sample size. That wording does not establish a guaranteed sustained quit or safety for every person and device. The publicly available abstract provides these summary findings, not a full account of trial methods and results.

Check the people and the control, not only the headline

A 2025 trial studied tobacco chewers over one month, comparing laser plus counselling with counselling plus sham laser. The authors reported some favourable measurements, but the between-group difference in reported quitting was not statistically significant. Neither those measurements nor the broad “tobacco cessation” title establish lasting cigarette abstinence. Counselling belongs to both packages; it cannot silently disappear from the claim.

Sham control means a simulated or inactive procedure. With otherwise comparable visits and support, it helps ask what the laser adds beyond the surrounding service and expectations. Ask whether both groups received the same other help, who knew the allocation, how quitting was defined and how missing follow-up was handled. A testimonial or pre/post score cannot answer all of those questions.

Use the evidence question in a qualified-help conversation

A useful question is: ‘For people smoking cigarettes, does this exact laser protocol add sustained abstinence compared with comparable support plus sham, and what are its safety limits?’ Keep the device, protocol, population, comparator and follow-up together. A mechanism story or the word ‘non-invasive’ does not itself answer the outcome question.

NHS Better Health offers local stop-smoking routes in England. Elsewhere ask a qualified local clinician or cessation service about established support and any proposed additional procedure. This page does not certify providers or device permission, choose treatment, set laser parameters or instruct you to stop existing care. No smoking or health history is requested here.

What to keep in mind

• Do not hide a positive finding or remove its limits.
• Publication date, outcome and population are separate checks.
• Bring the exact protocol question to qualified local support.
