ok, after a little bit of research i retract part of my statement, it is possible to get physical withdrawl symptoms if you're a really heavy smoker, when i quit i experienced only phychological which is where iw was comming from, but after looking it up i retract that.
i still warn of trading addictions though, because a heavy opiate addiction will always be worse than a heavy pot addiction, so i would be very weary of using opiates of benzos to aid your withdrawl if you have an addictive personality. a few benzos likely would help get over it, but from your post i'd be very weary of becomming addicted to those, as withdrawl from them can actually pose health risks.
I still maintain that phychological is the hardest part to break, and the easiest way to do this would likely be to try to take yourself out of situations where you usually smoke. if its certain friends then dont hang out with them for a week, make sure you dont buy any, spend a little time out of town, i dont know your situation but you need to evaluate how to break your phychological addiction as well as getting over physical
