If you happen to be one of millions of cannabis users who instinctively makes pot with tobacco when rolling joints, this is a habit you may want to think about getting out of. The reason being that half the time when you find yourself craving a bit of weed, it might actually be nicotine that you are craving. While it is a well-documented fact that cannabis itself is not addictive, tobacco is one of the most incredibly addictive substances on the face of the Earth. Which means that if you mix tobacco with your cannabis, it is largely inevitable that you will find the habit much more difficult to kick, or even cut down on.
