I see it as being useful to enter altered states of consciousness where subconscious inhibitions don't apply and you may experience a different perspective of something. Very useful stuff, not that i encourage the partaking in the glory of mother earth :P
I replied to the thread mentioned above. KTS in particular was mistaken in her assertion that one can fatally overdose on Marijuana. This is incorrect. Here's a repost of my previous reply...
I must correct an error posted by KTS about marijuana. I have done a LOT of research on Marijuana including recently attending a class at "Oaksterdam University" in Oakland. Oaksterdam is a training program for the quasi-legal cannabis industry in California. KTS states that one can ingest a lethal dose of cannabis if eaten. This is incorrect. There is no way on the Gods' green earth to overdose from marijuana, assuming we define overdose as taking enough to kill you (by itself). In defining the safety of drugs, the FDA has developed the LD50 standard. This standard provide a dosing level at which have the people taking this much will die. For instance, Valium will cause death in half of the people taking it when ten time the therapeutic dose is taken. Marijuana has no known LD50, though some researchers have put a theoretical number at between 150 to 1500 pounds consumed in 15 minutes. In other words, it is impossible. That said, when eaten, it IS possible to consumed enough to have a very bad experience. This usually happens when people eat, say, a brownie, then 30 minutes later say "I'm not feeling anything", so they eat another and possibly another. These folks are not going to have a fun time, because they will be VERY VERY stoned...for a long time. The only thing you do at this point is to ride it out....but you aren't going to die, even if you feel like you are.
Its also good to remember that the DEA's OWN administrative law judge declared that marijuana is "one of the safest, most therapeutically active substances known to man." It is safer than aspirin. It is safer than Tylenol. It is safer than coffee.
It depends on what you ingest. Many of the strains being developed are much more potent than they used to be, and that's not even including the effects of adulterants. This article also provides some further reading:

I agree that marijuana will not kill you; but it will certainly scramble your brain if you eat too much; or smoke too much! And if you are "compelled" to smoke it; use the leaf,not the resin! There is no doubt that the drug has medicinal uses; but so has Opium!
All "drugs" are useful; and all can be dangerous! Some extremely so! You might survive a dose of Heroin; not so Aconite (Wolfbane).
I must take issue with the article that user113004 posted. Unless you can consume over 1000 pounds of cannabis in a span of about 20-30 minutes...and I am not exaggerating on those numbers...you will not die from cannabis (assuming you don't mix it with something else like alcohol, or do something stupid like try to drive a car or operate heavy machinery). Even if you consume the most potent variety ever bred you cannot kill yourself simply by consuming cannabis. Will you be REALLY REALLY Stoned? Yes. Can you have a negative and possibly frightening experience. Yes. But you won't die or suffer long term health problems. The reason for this is that cannabis acts by altering higher brain functions, which is the reason you feel high. Other drugs that CAN kill you, like opiates, act by inhibiting LOWER brain function, otherwise known as the autonomic nervous system. That portion of the brain regulates such things as heart rate, breathing, digestion, etc. Taking too much of things like cocaine or opiates retards (or accelerates, depending on what you're taking) these functions and shuts down the body's ability to regulate these important bodily functions...or in the case stimulants, accelerates them to point of cardiac arrest. Cannabis acts by altering higher brain function, which is the portion of the brain that controls reasoning, perception, language, etc. This is why everything might seems funny, or time moves at a seemingly different pace than normal, or you end up talking like the guys in the Cheech and Chong movies. As for the article mentioned in the previous post...it is pure propaganda, like the lies the 1974 Tulane study tried to push on the world. Did the monkeys they used suffer brain cell death? Yes they did. Was it from Cannabis? No. It was from the fact they they gave the monkeys SOOOO much cannabis smoke and so little oxygen, that they asphyxiated. So not only did they perpetrate lies on the public, they committed unspeakable acts of cruelty on our primate cousins.
