point 4: although there is know way that weed is anywhere as physically addicative as alcohol, any heavy smoke who has to stop smoking will get some mild physical withdrawl problems, such as innsomnia and poor appertite.
Point 1 : Poison or not, it won't matter. Many good things can result from poison; poison isn't always negative unless it becomes dangerous, ie alcohol poisoning. You will never smoke enough marijuana to reach lethal levels. Another good example of this is Botox. Read this.

Basically, they take one of the most potent and lethal poisons ever known; one that can kill with just mere nanograms of the material (Botulinum), and use it to control muscular movements and spasms.

Point 2 : A "Whitey" is not a serious illness. Ever seen someone puking blood while emptying their stomachs from smoking weed?

Point 3 : Go to that website in my Point 1, and then go here.

Here's a quote on the subject, from that site.
Some research suggests that marijuana has no significant effectâ??good or badâ??on the immune system of people living with HIV. Studies from the Multicenter AIDS Cohort Study evaluating outcomes in 1,662 HIV-positive users of psychoactive drugs (marijuana, cocaine, LSD, etc.) found that none of the drugs were linked to a higher rate of HIV disease progression or loss of CD4+ cell counts. Of the men who took part in the study, 89% reported using marijuana in the preceding two years. A recent study, presented in 2000, examined the short-term impact of marijuana, dronabinol or placebo on HIV levels, CD4+ cell count and HIV levels. After twenty-one days, the use of marijuana did not appear to have harmful affects. Much longer-term studies are needed before concluding that marijuana use is either safe or unsafe for people living with HIV, however.

and another ...
Itâ??s not at all clear that this kind of weight gain, that consists more of body fat than of lean muscle, will benefit the overall health and longevity of a person with HIV-related wasting. However, if medical marijuana is combined with a comprehensive nutritional and weight maintenance program, as well as exercise, it may prove useful. Because of these concerns, it is important that evaluating the medical effects of marijuana not be limited to measuring weight gain, as this may lead to false conclusions about its value.

When considering all the safety factors associated with marijuana use, itâ??s important to weigh these factors against the harm being done by wasting. What may sound harmful to a healthy person may seem irrelevant to another when compared to the alternatives they face.

Point 4 : In certain cases, I'm sure it can be psychologically addictive to certain people; but to the general populace, it is not nearly as addictive as is alcohol, nor as dangerous.
