I would say it was neutral, hardly ground breaking.
This was a short term pilot observational study over a couple weeks for use of e-cigs at home in place cigarettes pre and post elective surgery.
Smoking is known to cause surgical complications and slow wound healing. All smokers are told to not smoke around the time of surgery for this reason. Adherence to the recommendation is notoriously poor.
This study was to evaluate whether using e-cigs was feasible and if patients would accept it. It was well-accepted by patients.
*snark alert* Surprise, smokers liked free nicotine replacement to use before and after surgery when told smoking causes surgical complications.
They do suggest given that the pilot shows acceptance, the next potential step would be to see if using e-cigs to replace cigarettes to reduce surgery complications actually has any benefit and no additional harms. That is the data that matters and would potentially change my stance.
They did not praise e-cigs nor advocate for their use as smoking cessation products or nicotine replacement even in the setting they studied.
