People can sometimes be addicted to drugs or alcohol because they make them feel “high”, and the rest of the world doesn’t know why.  Somebody who is so addicted would have the problem of smelling like cannabis when they were not actually high.  People who don’t experience addiction might not really understand how strongly this would be a problem.  I am not a medical professional, but I do believe I understand the problem well enough that I could try to answer your question.  If you really want to go to a medical professional about it, I could help you find one online.  However, I would recommend going to a doctor because I know you will be satisfied with the answers, and will understand them better.

You don’t have to worry about smelling like pot unless you’re smoking in your own home. If you’re going to be in public, just try to keep your activities as discreet as possible.  

 If you smell like pot, ask yourself if you’re self-conscious of how you smell. Can you be with friends, who don’t care about this, and smoke?  If you want to be able to smoke where you need to be, without any concerns about the smell, then try smoking outside.  Or just wear clothes that are always really smelly.  The scent is usually only in your clothing or on your skin, if you’ve ever had pot.  If you don’t have pot on you, and you haven’t had it, you’re not going to have the smell either.

 If you feel self-conscious of how you smell, and you really don’t want people to know you smoke weed, or you want to cover the smell when you’re doing something in public, then a deodorant spray, lotion, or even the tiniest amount of perfume will probably do the trick.  But try to keep it subtle.
