We don't know yet. There are many patients who use a vaporizer with gradually decreasing nicotine concentrations to wean themselves off cigarettes and nicotine. However there are also patients who seem to increase their nicotine needs, or who go back to cigarettes after vaping.

We also don't have long term studies on the risks and benefits of vaping compared to smoking. Early evidence suggests vaping in general is likely safer, but still not exactly safe. Combusted tobacco contains at least 50 substances known to cause cancer. E cigarettes have been found to have at least 2 cancer-causing substances. 

Medications like chantix, bupropion, and nicotine replacement products like gum and patches are a much safer way to quit than vaping.
