A new study has been published by Cochrane titled “How effective are medications and e-cigarettes for quitting smoking, and what works best?

cochrane 12-9-23

Various therapeutic methods of quitting smoking are discussed to help find the most effective.

“E-cigarettes, and the medicines cytisine (otherwise known as Tabex) and varenicline (otherwise known as Chantix and Champix), appear to help the most people to quit smoking, followed by using two types of nicotine replacement therapy at once (nicotine patch and another type, such as gum or lozenge).”

Existing Randomised Controlled Trials (RCT) were examined where the participants received a random product to assist in stopping smoking.

There were 332 studies which met the criteria and 319 provided the information required for the analysis.

Altogether there were 157,179 cigarette smoking adults who took part mostly in the USA and Europe.

The studies compared the effects of the following assistance…

  • no medicine/e-cigarettes for stopping smoking
  • e-cigarettes that did not contain nicotine
  • placebo (a dummy medication)
  • other types of stop smoking medicine or e-cigarettes.

Results

E-cigarettes, varenicline and cytisine all came out as the most effective treatments.

For every 100 people…

  • 10-19 are likely to quit using a vape
  • 12-16 using varenicline
  • 10-18 using cytisine
  • 6 using no assistance or a placebo

Conclusions

I have copied and pasted the conclusion from the document…

“The most effective interventions were nicotine e‐cigarettes, varenicline and cytisine (all high certainty), as well as combination NRT (additive effect, certainty not rated). There was also high‐certainty evidence for the effectiveness of nicotine patch, fast‐acting NRT and bupropion (Zyban). Less certain evidence of benefit was present for nortriptyline (moderate certainty), non‐nicotine e‐cigarettes and tapering of nicotine dose (both low certainty).

There was moderate‐certainty evidence that bupropion may slightly increase the frequency of SAEs (Serious Adverse Events), although there was also the possibility of no increased risk. There was no clear evidence that any other tested interventions increased SAEs. Overall, SAE data were sparse with very low numbers of SAEs, and so further evidence may change our interpretation and certainty.

Future studies should report SAEs to strengthen certainty in this outcome. More head‐to‐head comparisons of the most effective interventions are needed, as are tests of combinations of these. Future work should unify data from behavioural and pharmacological interventions to inform approaches to combined support for smoking cessation.

I am an engineer and Technical Author by trade. My journey in vaping began around 2016, in the days of Tornado tanks, Ego batteries and Variable Voltage. It took me a few years to fully quit smoking but I finally stopped in June 2019 and that is all thanks to vaping! 20mg Nicotine Salts are my hero! Oh and I am partial to a nice pod mod and Bubblegum e-liquid! I have reported on the latest news on Ecigclick since 2017 and love being part of this great team! My passion for Tobacco Harm Reduction has also led me to becoming a Trustee for the NNA (New Nicotine Alliance) aiding in Advocacy
