The US Surgeon General has said:

Smoking cessation [stopping smoking] represents the single most important step that smokers can take to enhance the length and quality of their lives.

It’s hard to quit smoking, but you can do it.  To have the best chance of quitting and staying a non-smoker, you need to know what you’re up against, what your options are, and where to go for help.  And to make matters worse, the majority of the presently available smoking cessation aids have proven to be ineffective in approximately 90% of smokers.

Aim

Pseudomonas putida, originally from soil in a tobacco field, is a bacteria who consumes nicotine as its one source of carbon and nitrogen through a specific enzyme.  Researchers aimed to test this enzyme’s potential effect as a therapeutic agent.

Results

This enzyme decreases the half-life of nicotine and prevented it from reaching the brain.  The researchers did not find any toxic metabolites produced when the enzyme broke down nicotine.

Conclusion

Future studies are needed, however, this enzyme could assist in smoking cessation – or to quit smoking.
