I love getting a healthy dose of carcinogens every morning.

While we're at it, let's take a look at some more bad things marijuana does to you.



Doesn't suprise me.



You're all going to end up retarded one day.
The effects of tobacco and cannabis smoking differ, however, as they affect different parts of the respiratory tract: whereas tobacco tends to penetrate to the smaller, peripheral passageways of the lungs, cannabis tends to concentrate on the larger, central passageways. One consequence of this is that cannabis, unlike tobacco, does not appear to cause emphysema. Also, unlike tobacco, regular cannabis use does not appear to cause COPD, either. Researchers have speculated on potential side effects from the fact that cannabis burns at a higher temperature than tobacco.

Cannabis smoke contains numerous compounds known to cause cancer. Surprisingly, however, scientific studies have failed to show higher cancer rates in cannabis smokers. A study published in 2006 on a large population sample (1,200 people with lung, neck, or head cancer, and a matching group of 1,040 without cancer) failed to positively correlate a lung cancer risk, in fact the results indicated a slight negative correlation between long and short-term cannabis use and cancer, suggesting a possible therapeutic effect. This followed an even larger 1997 study examining the records of 64,855 Kaiser patients, which also found no positive correlation between cannabis use and cancer. It has been noted, separately, that THC, a dilative agent, may help cleanse the lungs by dilating the bronchia, and could actively reduce the instance of tumors. Additionally, a study by Rosenblatt found no association between marijuana use and the development of head and neck squamous cell carcinoma.

Like tobacco smoke, marijuana smoke contains tars which are rich in carcinogenic polycyclic aromatic hydrocarbons, which are a prime culprit in smoking-related cancers. However, cannabinoids themselves are not carcinogenic. An obvious way to protect smokers' health is therefore to minimize the content of smoke tars relative to cannabinoids.

The most obvious way to do this is to bypass smoking completely by simply eating the cannabis as "space cakes".

Another way is to increase the THC potency of the marijuana (see also section on potency above). Assuming smokers adjust their smoke intake to the cannabinoid dosage, the higher the concentration of cannabinoids, the lower the amount of tars they are likely to consume to achieve their desired effect.

Vaporisers, by heating the cannabis oils to be inhaled without combustion, almost avoid the risk altogether. A 2000 study conducted by NORML and MAPS found that the two tested vaporizers performed up to 25% better than unfiltered marihuana cigarettes in terms of tar delivery.

Surprisingly, the same study found that water pipes (bongs) and filtered cigarettes performed 30% worse than regular, unfiltered joints. The reason is that waterpipes and filters filter out more psychoactive THC than they do tars, thereby requiring users to smoke more to reach their desired effect. The study does not, however, rule out the possibility that waterpipes could have other benefits, such as filtering out harmful gases such as carbon monoxide.

Not sure what link will take you to this info but you should go to them all.
