I have been a frequent user of cannabis and have finally come to an understanding of the negative impact it has had on my well being. I have always heard there are zero physical withdrawal symptoms, however, when I quit using the drug I notice this is not the case. While the withdrawal is not much of an issue, I do notice headaches, stomach aches, dizzy spells, along with a general feeling of discontent. I believe mental and physical aspects are so closely connected that to say cannabis has no physical withdrawal is just ignorant and biased. Tell me what you think and is it normal, or do I have a stomach problem?

Cannabis is known to treat stomach conditions, increase appetite, treat headaches, insomnia, blah blah laundry list. Your body is used to having it in its system to take care of those things. Now, without it, you're feeling those more. It's not addiction per say, but you become dependant on any substance you put in your body regularly.
I wouldn't call the distinction biased. It's an important distinction, but it's also important to remember that even if something is at the core, physical or at the core psychological doesn't mean it won't have effects that carry over into the other one.
