You will probably still get something out of it.

Its too bad you don't really go for it because this cleanse will clean out the reason for the continued cravings.

It cleans out the toxons left behind from all the earlier cigarettes.
Without the toxins you probably wouldn't be addicted to them.

You know how you had to smoke for a while in the beginning before you were actually addicted.
Thats because your body had to build up some of the toxins first.

You probably wouldn't clean out everything on one cleanse but it would be easier to hold off the temptation to light up.
