Marijuana for appetite stimulant to fight anorexia or malnutrition?

Hey GC, so last year, I was having problems with my appetite and diet.
 
I felt like I wanted to eat more food, but I just didn't have the appetite to eat that much food...
 
Rather than finishing my whole meal, I wanted to stop eating and just save it for later, or just throw away the rest of my food.
 
Or I would rather just taste something that didn't make me full, like smoking weed, drinking tea, chewing gum, something that has flavor but doesn't make me feel full.
 
So I was eating less last summer, and by the end of the year, I didn't even feel like eating when I was hungry. I felt like I couldn't afford to pay for food, didn't have enough money for any expensive foods, so I would only get the cheapest food I could find, so that I wouldn't run out of money.
 
At the same time I had serious pains in most of my whole body, particularly around my jaw or my teeth, but also in my ankles, knees, back and shoulders. Well, it felt like my whole skeleton was just entering a new developmental state, where I don't think I'm growing anymore in terms of height or weight. But no doctor or medical advisor said that anything was wrong, I got x-rays of my teeth at the dentist and they said it's healthy.
 
Regardless considering my age, I think some growing pains are normal. I only thought that it was related to smoking cigarettes because I had pain in my jaw, even though the pain might or might not have been caused by smoking. There's no direct correlation, and I'm pain-free right now, even though I've been smoking my pipe for the last several days.
 
But my main question is:

Can marijuana be used as an appetite stimulant to treat anorexia or malnutrition?
 
I'm not a doctor so don't think just because I'm relating marijuana to an appetite stimulant, that you can get a prescription from me. I'm just asking the question.
