The study results are obviously discomforting to waterpipe enthusiasts, many of whom prefer the cooler, milder smoke they produce, and have naturally assumed it is also more healthful. Unfortunately, however, the study indicates that waterpipes may actually be counterproductive in increasing consumption of carcinogenic tars.

Marijuana Water Pipe and Vaporizer Study

It may be counter-intuitive to many, but joints appear to give the best ratio of thc to tar. Or of course, you could just vape.

seriously. those studies are fail. the theory is there but there are too many other factors.

most people report getting higher off a bong. i know i feel like that. i probably do get more tar in my lungs since i inhale more deeply and hold it longer.

but i guarantee i get more thc smoking out of my bong than i would a pipe or joint. i doubt filtering it through water will take out as much thc as the smoke that doesn't go into my lungs (aka the smoke coming off the lit end of the joint or smoke coming off a bowl).

and you never get scoobies


the machines they use are fail as well. read up more on it. there's a lot of information about them.

Abstract
Objective  Although extensive work has been done on cigarette smoking and its effects on pulmonary function, there are limited number of studies on water-pipe smoking. The effects of water-pipe smoking on health are not widely investigated. The aim of this study was to determine the effects of water-pipe smoking on pulmonary permeability.
Methods  Technetium-99m DTPA inhalation scintigraphy was performed on 14 water-pipe smoker volunteers (all men, mean age 53.7 ± 9.8) and 11 passive smoker volunteers (1 woman, 10 men, mean age 43.8 ± 12). Clearance half-time (T 1/2) was calculated by placing a monoexponential fit on the time activity curves. Penetration index (PI) of the radioaerosol was also calculated.
Results  PI was 0.58 ±0.14 and 0.50 ± 0.12 for water-pipe smokers (WPS) and passive smokers (PS) respectively. T1/2 of peripheral lung was 57.3 ± 12.7 and 64.6 ± 13.2 min, central airways was 55.8 ± 23.5 and 80.1 ± 35.2 min for WPS and PS, respectively (p ≤ 0.05). FEV1/FVC% was 82.1 ± 8.5 (%) and 87.7 ± 6.5 (%) for WPS and PS, respectively (0.025 < p ≤ 0.05).
Conclusions  We suggest that water-pipe smoking effects pulmonary epithelial permeability more than passive smoking. Increased central mucociliary clearance in water-pipe smoking may be due to preserved humidity of the airway tracts.

on another note, i read a study one time about how filtering marijuana smoke makes it more healthy in other ways.

it was about a chronic marijuana user, a lady, who smoked only marijuana her whole life. now she didn't get cancer, but she developed a hole in her lungs. the doctors said if she had filtered it through water, she would have never developed the hole in her lungs. i forget the medical term for it. i really wish i could find this study... if anyone has seen it let me know it was in shroomery news withing the past few years... LOL

this isn't it, but i found what the article was talking about:

pulmonary epithelial permeability - still don't know what this means.

Mucociliary Clearance, also referred to as mucociliary apparatus or mucociliar clearance (MCC) , derived from mucus , cilia (cilia of the tracheal surface epithelium in the respiratory tract ) and clearance describes the self-clearing mechanism of the bronchi.

The main bronchi down to the alveoli are lined with a respiratory epithelium. On that cilium is existent, bearing hair-shaped structures on its surface (cilia). The cilia are surrounded by a thin fluid film of mucus. On top of that is a second viscous film of mucus, in which foreign particles and microorganisms get stuck. Within the thin fluid film of mucus the cilia act out movements coordinated in direction towards the Pharynx. Thereby the viscous film of mucus including its freight is transported off in direction towards the mouth, where it is either swallowed or coughed off.

Important for good mucociliary clearance are the number of cilia, their structure, activity, and coordinated movement. Optimum functionality of mucociliary clearance presuppose a temperature of 37 °C and an absolute humidity of 44 mg/dm³ corresponding to a relative humidity of 100 %. Under the condition of insufficient temperature and humidity, after a short time the ciliary cells suspend their transport function. Under such circumstances, bacterial germinal colonization is facilitated. Pulmonary infections and damaging of the pulmonic tissues may be the consequence.

High humidity enhances the functionality of the mucociliary clearance. Two methods of supporting mucociliary clearance are the active and the passive respiratory gas humidification, which in particular are applied in mechanical ventilation.

i know you're intelligent by some of your posts, but really?

HB, i get what the study says. it only is measuring THC and tar. you think these are the only two issues related to lung health? you're wrong.

please read all the posts in the thread before making such an ignorant comment.

and besides, based on that one post, if you feel you get higher through a bong you might actually smoke less than you would have if you smoked a joint. wow did you ever think of that??? the study can't measure that! that means you could get less tar in the long run by smoking less material even though the ratio is higher. make sense? and the problem with that study is it is just ONE study. that's why i provided other studies. i provided another study that says it's more harmful and another saying its less harmful.

here is the one that talks about water pipes being healthier:
