"Although cannabis smoke contains many of the same carcinogens as tobacco smoke,[77] current scientific data supports the possibility that cannabis smoking may not induce cancer.[78] Of the various methods of cannabis consumption, smoking is considered the most harmful; the inhalation of smoke from organic materials can cause various health problems (e.g., coughing and sputum). Isoprenes help to modulate and slow down reaction rates, contributing to the significantly differing qualities of partial combustion products from various sources.[79][80] Compared to tobacco much less cannabis material in weight is burned, with the average hand rolled cigarette at about 1 gram, tobacco or cannabis. Commercial cigarettes have numerous additives, many of which modify combustion in such a way to create a very consistent aerosol at any given air flow rate, perhaps to maximize nicotine delivery/bio-availability, and thus reduce total amount of smoke consumed to nicotine crossing the blood brain barrier. A relative abundance of terpenes and other higher molecular weight, adhesive molecules results in a smoke with higher mean particle size, as well as a corresponding higher deposition rate of particulate matter. This means more is deposited on the bronchioles, and larger airways, which the lungs can clear easier, as less of the very fine, highly toxic amorphous particles reach the delicate alveoli. Cilia cannot "sweep" up the combustion products effectively. Subjective lung irritation not based upon the amount of matter crossing the semipermeable gas exchange surfaces deep in the lungs, rather the primary factor is amount of matter which adheres to motile cilium. This also contributes to a noted expectorant effect of any smoke to some extent, due to the defense system the mucus membranes in the lungs possess. The study concluded: "A significant interaction revealed that the impact of a vaporizer was larger as the amount of cannabis used increased. These data suggest that the safety of cannabis can increase with the use of a vaporizer. Regular users of joints, blunts, pipes, and water pipes might decrease respiratory symptoms by switching to a vaporizer".[81] Another study found vaporizers to be "a safe and effective cannabinoid delivery system."[82][83]
In a 20-year study of 5,000 young adults, researchers found that, unlike tobacco use, smoking cannabis once a week or a bit more doesn't harm the lungs, with less clear results regarding heavy users due to a lack of very heavy users in the study. In fact, the study found that occasional cannabis use actually increases both lung capacity and volume over the years, possibly because cannabis smokers often take deep breaths, which exercises lung tissue. The correlation only decreased after the equivalent of about ten years of smoking cannabis once a day. Only lung volume and capacity were examined, not throat irritation, coughing, or lung cancer.[84]"
Do you want to see a study which proves that cigarettes aren't harmful at all, or study which proves that DDT is complete harmless for the people? My favorite is a study which proves that men who smokes one cigar per day are healthier than those, who doesn't smoke at all. Why? Because I smoke a cigar every now and then, and know how relaxing it is as a fact, and everything relaxing will lower stress levels, so it is good to your health in the long run. Or is it? What comes that study about the weed, it make some claims based on the fact that these 5000 smoke cannabis one joint once a week. Who does that? Is it some kind of national law that you can smoke only one joint per week? How about two? If I smoke one cigarette per week, will it be as harmful than smoke 20 per day? Even ape can learn to read, but to understand what you have read, that is the part where you need some brain capacity. You can smoke one cigar per week inhaling it, and it has no long term effects to you what so ever, but what happen if you smoke more? Also nothing? How stupid man can be?? Do you know what "zero research" means?
Why it is always easier to adopt pro cannabis claims, than the facts which proves negative effects? If I link here 25 000 studies which completely proves that cannabis has negative health effects, all that can be overruled by linking one page of pro cannabis propaganda? Why it is like that? Because as I have repeatedly said, internet has given a voice for incredibly stupid people, and that we all should notice every fucking time we open www. When some one write an argument in the internet, people who comments it wouldn't be at the same level as him, more likely they are from that bunch who IQ is smaller than their shoe size. Why? Because their number is large, because this world is filled with drooling idiots who just can't comprehend simplest things
