Odd how no one mentioned vaporizing marijuana. Done correctly, you don't inhale any carcinogens because nothing burns, and you still have the same level of control of how much pot you ingest as you would with a joint or pipe, as opposed to eating it. Of course, with drug paraphernalia being illegal in most places, researching and buying an effective one is extremely difficult and expensive, and so most people simply resort to smoking it. Isn't the war against drugs great?

The evidence that smoking cannabis causes lung cancer is limited. There are a number of problems with assessing the risk:
1) cannabis use is far less prevalent than tobacco use
2) the quantity of cannabis smoked tends to be less than tobacco (particularly with modern highly potent 'skunk' varieties)
3) People may be less likely to admit to cannabis use during a medical interview
4) Cannabis use tends to be maximal in the younger age groups. Cancer is primarily a disease of old age and is very rare in the range 20-40 years

There are no conclusive studies proving that lung cancer risk is significantly increased in cannabis users, however, there are a growing collection of individual case reports of tongue, throat and lung cancers in young otherwise healthy people, whose only risk factor was smoking of cannabis. Additionally, cannabis has been linked to the development of 'pre-cancerous' changes in the lungs.

Cannabis smoking, just like tobacco smoking, is strongly linked with other types of lung disease - emphysema, bronchitis, chest infections, cough etc. with the distinction that they seem to occur earlier. Respiratory physicians have known for years about 'cannabis lung' - a crippling, severe form of emphysema which affects young people and is very strongly associated with smoking cannabis.

Tobacco smoking is well known to cause problems outside the lungs - it causes furring up of the arteries leading to heart attack and stroke. This has not been proven with cannabis. However, cannabis has other effects on the cardiovascular system - and has been implicated in a number of sudden deaths (presumably a result of an abnormal heart rhythm - a known side effect).

Not quite . . . that's why Marinol - the synthetic THC for cancer/aids/nausea - is generally liked less than smoking it.

It generally takes more than twice the pot to eat (than smoking) to get the approximate effect. It also takes much longer - an hour or so - and should be eaten on an empty stomach (other than fat or oil in the brownies). Too expensive for most people.

Also, eating produces a 'body high' compared with the more 'mental high'. ANd SEVERE munchies. ;)
The reason Marinol sucks is because there are far more chemicals in cannabis than just THC. There are some 60 cannabinoids, and all the different concentrations of them give the different effects from strain to strain. I doubt there are very many people that prefer Marinol to smoking it. I don't think THC by itself gives you the munchies, which is what say, AIDS patients, want.

The high is quite a bit different though. It's more of a body high, not concentrated so much in your head. And yes, you need to eat much more compared to smoking it, and the effects take longer to kick in.. BUT, they last longer.

A recipe that I found calls for a CUP of marijuana! Isn't that insanely expensive? I haven't smoked in 5 years but a little baggie used to set me back 10 bucks
A cup would be for a party batch. . . figure 2 grams per person.

Per person or per brownie? How many grams is your typical dime back/
A 10 would be about 0.875g.
Maybe around those parts a dime is $10 worth of kind, but a real dime is a 1/10 of an ounce or 2.8gs.

On the subject of cancer, I read in a health book that cigarettes contained trace amounts of some radioactive material and that's why they give you cancer. Pot just has more stuff to irriate your lungs. I read the same thing that Eli did though, apparently some of the cannabinals found in pot smoke help to prevent cancer in lung tissue.

Hmm.. Around here "10" would refer to a "10$ bag", or 1/4th of 1/8th of an oz. :p

Heh...

You can use applesauce in place of butter or oil when cooking. Gives a sweeter flavor, and it's lower in fat :p
WRONG!

THC needs fat to digest properly.
I think you mean THC is soluble in fat.

You really need a lot of sativa for a decent batch of brownies. I only got a tiny buzz when I used a dime for an 8"x8"x1" pan of brownies.
