The effects of marijuana withdrawal typically last no more than a few months though, although the chance of some genetic perk (I've seen someone who didn't break down THC in their body, and thus remained with THC in her blood for weeks on end if smoking, instantly getting highly addicted) altering that timespan is never completely ruled out. In your case however I would say it's more a longing for an activity and the emotion she felt at the time, than something caused from withdrawal.
I don't mean to be rude, but that is medically impossible. There is not a single medical documented case of any mammal not being able to metabolize THC, in the world. Things like this just spread urban myths; even for the anti-drug crusade it just causes people to lose credibility. Here's a good link to the facts on THC metabolism, notice it's a medical text and not a pro-or-anti pot site:
http://www.druglibrary.org/schaffer/library/studies/ledain/ldc2d.htm
THC is extensively metabolized in humans, primarily in the liver, but also in other tissues, including the lungs, and the various metabolites are excreted in the feces and urine. Little or no free or unaltered THC is eliminated from the body. Although much of the administered THC is almost immediately bound to lipoproteins in the blood plasma, 338,643,669 metabolism apparently begins nearly as soon as the drug enters the body, and metabolites have been identified in plasma within minutes after administration. The major THC metabolites are mono- and clihydroxy compounds. Deriving from these primary metabolites are a large number of secondary Metabolites. THC is progressively metabolized. primarily by non-specific oxidases in the microsomal enzyme system in the liver. This may be a significant factor for drug interaction considerations, since many other drugs are metabolized by the same system.
In man, studies of radio-labeled materials suggest that about one-half of the THC metabolites are excreted within a few days, and most are eliminated within a week, although small amounts may be retained for longer periods.
The fact that children who use it suffer permanent brain damage in the hippocampus and amygdala, inducing permanent damage to the memory both short and long term, and damaging the ability to concentrate, as well as lessen the control over emotions, possibly leading to overly agressive behaviour.
Many doctors would disagree with you:

In addition, marijuana induced mental disorders do not go away. Once a person has gone into a psychosis because of marijuana use, they will never achieve the same amount of mental stability as before. All the more true for schizophrenia triggered by marijuana, if that happens to you, you're basically fucked for the rest of your life. Mental stability can only be achieved back through the use of rather nasty anti-psychotic medication with many heavy side effects and a lot of regulation on a person's daily life.
I worked in the field of drug rehabilitation for years and I never saw a single case of "permanent marijuana induced mental disorders" - there is a casual link between schizophrenia and marijuana use in that there is a belief among some - not all - medical doctors and scientists that marijuana use might trigger pre-existing schizophrenia; not cause it.
Again, it's fine to be anti-drug but get your facts correct.
And in addition to that, smoking marijuana causes several times more lung damage than smoking tobacco.
Inhaling burning organic material of any kind is not good for the lungs; many people vaporize it or eat it for this reason.
Saying that it is more dangerous than tobacco is misleading, though. They are dangerous in different ways; marijuana appears to be less carcinogenic over long term use, in fact. Most studies done linking marijuana to lung cancer except one single NZ study show that there is no increased risk of cancer with marijuana unless mixed with tobacco.
I don't smoke marijuana, but I do try to be factually correct when I discuss it. Scaremongering isn't a really good tactic, sane and lucid education is.
The final argument is of course that there is no reason for drug abuse. No healthy person needs marijuana, and nobody needs marijuana for it's main effect.
Well, no healthy person "needs" anything but food, water, and shelter but that doesn't stop us from seeking out activities that light up reward centers in our brain - no healthy person needs video games. No healthy person needs gambling. No healthy person needs sex. See where this is going?
You must know that is not true. THC poisoning is something which is very real. In animal testing, a dosage as low as 29 mg per kilo of body weight already proved to be fatal. To compare: that's just 2 grams of THC in a person weighing 70 kilos. And considering the high THC content of many modern marijuana plants, smoking 6 grams may already induce this potentially fatal dosage.
This is perhaps the most erroneous statement you have made. Again, from a medical text; not a pro-pot site:
http://www.druglibrary.org/schaffer/library/mj_overdose.htm
According to which US Government authority you want to believe, the lethal dose of marijuana is either about one-third your body weight, or about 1,500 pounds, consumed all at once.
In summary, enormous doses of Delta 9 THC, All THC and concentrated marihuana extract ingested by mouth were unable to produce death or organ pathology in large mammals but did produce fatalities in smaller rodents due to profound central nervous system depression.
Again, that's a pretty safe track record considering the MILLIONS of people who use marijuana and have used it over thousands of years; not a single recorded ability to produce death OR organ pathology in any large mammals. It's among the safest of all drugs.

Also, there have been four documented deaths in the US alone from the THC-based pill Marinol.
Which is one reason medical patients are reluctant to take the pill as opposed to using a plant with a proven safety record:
http://patients4medicalmarijuana.wordpress.com/2009/08/24/does-the-pot-pill-work-a-look-at-marinol/
And let's not forget that even a non-lethal dosage can turn out very nasty if you get a bad trip. And once in it, there's no way out, and that person gets to enjoy up to two straight hours of intense agorophobia, among other effects.
I absolutely agree with you here. Marijuana can cause panic attacks in certain users. So can most drugs.
Not before ingesting a massive dosage of alcohol. Alcohol is less poisonous than THC.
Not in the amounts commonly ingested, it's not. And I don't even think I need to compare alcohol related deaths vs. marijuana related deaths in countries where both marijuana and alcohol are legal - ask any Dutchman or citizen of Portugal. Or doctor. Not internet scare article; doctor.
And most alcohol related fatalities are not in children, but in the elderly. Mostly this is caused by an external factor that makes a person drink. Pensioners for instance are liable to start drinking because the daily rhythm and structure of their occupation is lost.
Do you work for an alcohol company? I don't mean to be rude again but alcohol is actually one of the LEADING causes of fatalities in teenagers and young adults. Mostly from car accidents, but occasionally from overdose as well.

http://pubs.niaaa.nih.gov/publications/aa68/aa68.htm
http://www.cdc.gov/nchs/fastats/alcohol.htm
And this one actually shows that most alcohol fatalities happen in the middle aged, not the elderly:
http://pubs.niaaa.nih.gov/publications/arh27-1/110-120.htm
If you're going to claim that, you must also be honest about the fact that this is only the case in elderly patients suffering from heavy addiction. You're talking about drinking heavily for at least ten years.
This is false. You can suffer from acute alcohol withdrawal symptoms at any age, and doctors often prescribe drugs like Valium and Xanax to help with alcohol related seizures, etc.
And it's not even the alcohol that kills, it's the withdrawal, because many bodily functions were geared towards taking a beating of a high dosage of alcohol every day. They're given alcohol to smooth the transition, just like addicts on other drugs receive methadone or other drugs to lessen the impact of withdrawal.
Again, do you work for Budweiser, friend?

This is also false. There's a medical code explicitly for "accidental alcohol poisoning death" - (ICD?9 code: E860, for those in the medical field) ... there is no such code for "accidental death by THC" even in countries where marijuana is legal.
From another government study:
The annual average number of deaths for which alcohol poisoning was listed as an underlying cause was 317, with an age-adjusted death rate of 0.11 per 100,000 population. An average of 1,076 additional deaths included alcohol poisoning as a contributing cause, bringing the total number of deaths with any mention of alcohol poisoning to 1,393 per year (0.49 per 100,000 population). Males accounted for more than 80 percent of these deaths. The rate was lower among married than unmarried people (i.e., never married, divorced, or widowed) and was inversely related to education. Among males, the alcohol poisoning death rate was higher for Hispanics and non-Hispanic Blacks than non-Hispanic Whites. Among females, racial/ethnic differences were small, but Black women had higher alcohol poisoning death rates than White or Hispanic women. Alcohol poisoning deaths tended to be most prevalent among people ages 35 to 54
I just hate seeing misinformation spread. Alcohol poisoning happens. Not extremely frequently, but frequently enough. "THC" poisoning doesn't happen from marijuana, the plant. Not a single.case.ever of a person dying from "THC intoxication" ... think about it.
Alcohol is a dangerous drug that ruins lives and causes deaths every day; mostly through drunk driving but also through overdose and withdrawal. To say that marijuana is more dangerous is just... ridiculous, from a medical and a rational standpoint.
Do you know what the standard treatment is for a marijuana-related "emergency room visit" ...? It's watching the patient and giving a sedative like Xanax until the panic attack passes.
For an alcohol related visit it often ends much more sadly.
