Marijuana smoke smells bad and I don't want it near me, my family, or may one who may be irritated by the smoke.

If it helps you for medical reasons, then it will be just as effective or more so by way of an injection.  That way, you are keeping to yourself and not sharing the unwanted smell of pot.  

If every "pro-Marijuana" users just admits that's they want to smoke it recreationally and it isn't for pain.  Marijuana should not be legal anywhere in America!
