To begin, you will first need to make sure you are ordering the correct model cartridge; NPRO (short cigarette-like sized) or NCIG (longer pen size)

Secondly, determine the nicotine strength based on your current smoking habits; some good guide lines are:

• Smokers who smoke full strength cigarettes should use medium or high cartridges
• Smokers who smoke lights should use medium to low strength nicotine cartridges
• Smokers who smoke ultra lights should use low strength nicotine cartridges
  
• Smokers who smoke menthol should use menthol cartridges
• Smokers who smoke regular should use tobacco flavored cartridges
