I quit smoking over a year ago, but lately i've been having cravings. can you help?!

i've been around two people on two different occasions while they were smoking. normally i don't do this, but one of the people is a very good friend of mine who recently started back up, and another is a good friend i haven't seen in over five years. do you think the smell triggered nicotine receptors in my brain, and that's why i'm having cravings again.? what should i do.? do i just avoid standing around people when they're smoking.?Health Question & Answer
