A bong (also known as a water pipe) is a filtration device generally used for smoking cannabis, tobacco, or other herbal substances. In the bong shown in the photo, the smoke flows from the lower port on the left to the upper port on the right.
In construction and function, a bong is similar to a hookah, except smaller and especially more portable. A bong may be constructed from any air- and water-tight vessel by adding a bowl and stem apparatus (or slide) which guides air downward to below water level whence it bubbles upward (\"bubbler\") during use. To get fresh air into the bong and harvest the last remaining smoke, a hole known as the \"carburetor\", \"carb\", \"choke\", \"bink\", \"rush\", \"shotty\", \"kick hole\", or simply \"hole\", somewhere on the lower part of the bong above water level, is first kept covered during the smoking process, then opened to allow the smoke to be drawn into the respiratory system. On bongs without such a hole, the bowl and/or the stem are removed to allow air from the hole that holds the stem.
The water can trap some heavier particles and water-soluble molecules, preventing them from entering the smoker's airways. The mechanics of a bong are compared to those of a laboratory gas washing bottle. The user puts their mouth at the top and places the cannabis in the tube, as shown in the picture.
Bongs are often either glass or plastic that use a bowl, stem, and water to produce smoke. Most glass bongs are made from heat resistant borosilicate glass, allowing the bong to withstand repeated use and heat exposure without breaking. After the bowl has been packed and water has been inserted into the bong, the substance is lit and the smoke is drawn through water to produce a smoother smoke than other methods of smoking do. To smoke a bong, the smoker must inhale in the bong so bubbles containing smoke begin to come from the stem. Once the bong has a fair amount of smoke built up, either the carb is uncovered or the stem is separated from the bong, allowing the remaining smoke to be inhaled.
However, a 2000 NORML-MAPS cannabis study found that \"water pipes filter out more psychoactive THC than they do other tars, thereby requiring users to smoke more to reach their desired effect\". In the study, smoke from cannabis supplied by the NIDA was drawn through a number of smoking devices and analyzed. This study looked at the tar to cannabinoid ratio in the gas in output by various bongs, as well as unfiltered and filtered joints, and vaporizers. The results showed that only vaporizers produced a better tar to cannabinoid ratio than unfiltered joints, but that within the cannabinoids produced, even vaporizers warped the ratio of THC (the psychoactive component of the smoke) to CBN (capable of producing medical benefits but is not psychoactive) in favor of CBN. This showed an unfiltered joint had the best tar to THC ratio of all, and bongs were actually seriously detrimental in this respect.
MAPS also reviewed a study that examined the effects and composition of water-filtered and non-filtered cannabis and tobacco smoke. It found that when alveolar macrophages were exposed to unfiltered smoke, their ability to fight bacteria was reduced, unlike exposure to water-filtered smoke. It also found substantial epidemiological evidence of a lower incidence of carcinoma among tobacco smokers who used water-pipes, as opposed to cigarettes, cigars, and regular pipes. \"It appears that water filtration can be effective in removing components from cannabis smoke that are known toxicants... The effectiveness of toxicant removal is related to the smoke's water contact area.\"
Specially designed water pipes, incorporating particulate filters and gas-dispersion frits, would likely be most effective in this regard; the gas-dispersion frit serves to break up the smoke into very fine bubbles, thereby increasing its water-contact area.\" These frits are commonly referred to as diffuser for the way that they diffuse (or disperse) the smoke as it exits the downstem, and usually consist of small holes or slats at the end of the downstem. This study suggests that a bong's smoke is less harmful than unfiltered smoke.
A gravity bong sounds like a high-tech scientific invention for smoking cannabis, but that's not the feeling you get when looking at one of these barebones, DIY bongs. A gravity bong, also known as a GB, Geeb, bucket bong, or sometimes waterfall bong, is a type of homemade bong that uses water and pressure to push smoke into the lungs. As the cannabis is lit, gravity pulls cannabis smoke into a bottle using water in a container to create suction.
Yes, and they're famous for it. When it comes to a gravity bong vs. regular bong, gravity bongs are usually made with larger containers (compared to traditional bongs and pipes) like 2-liter bottles. This means they can hold way more smoke.
Not only do they produce larger, more concentrated hits of cannabis, but the force created by the water vacuum also affects how quickly and intensely the smoke enters and fills the lungs. Almost anyone who has used a gravity bong will tell you that they are not for the faint of heart and best left to more experienced and seasoned cannabis consumers.
Homemade gravity bongs are just as easy to use as they are to make. The general idea is to use the vacuum pull created by the water to draw a large and concentrated amount of smoke. First, the gravity bong bowl is filled, and the top of the water bottle or container is submerged in the water until only the bowl is out of the water. As the gravity bong bowl is lit, the user slowly pulls up on the bottle, which creates the suction needed to pull as much smoke from the cannabis as possible.
Even though they are called gravity bongs, they don't operate as traditional bongs do. Although both produce very concentrated hits of smoke, only the regular bong forces the smoke to pass through the water, which can help filter the smoke and cool it down.
If you are reading this, chances are you sound as though you are choking on a chicken bone every time you smoke weed. Fortunately, there are a few things a person can do to help them cough less and join the ranks of the professionals. Pay close attention here, kids, your reputation is on the line.
There is mixed evidence on the effects of cannabis smoke on the lungs. This is because of a relative lack of literature combined with concurrent tobacco smoking and the reports of conflicting outcomes.
A study conducted at the UC Berkeley School of Public Health and published by the journal JAMA Network Open on Wednesday declared that secondhand cannabis smoke released during bong hits contains fine particulate matter at a concentration dangerously higher than that released by secondhand tobacco smoke.
An aerosol monitor measured the air quality before, during and after each session, which lasted up to two hours. The data from the monitor was downloaded and compared to data of subjects smoking tobacco through a hookah in a similar setting. The results showed that cannabis smoke from the bong produced four times the particulate matter as the smoke produced by tobacco.
Bongs and Berkeley are, of course, synonymous. For generations, many, including UC students and street vendors, have enjoyed the expedient high that comes from bong hits. As opposed to a marijuana cigarette, or joint, a bong has a large opening at the top allowing for a tremendous intake followed by a dramatic outflow of secondhand smoke, when the person taking the hit can hold it in the lungs no longer.
With their accompanying sound of gurgling water, bongs were made part of the culture through the stoned antics of comedians Cheech & Chong in the 1970s and are still the smoking vehicle of choice at the 420 celebrations in Golden Gate Park and elsewhere.
But almost as classic is the sample that begins the song: \"She was living in a single room with three other individuals. One of them was a male, and the other two Well, the other two were females. God only knows what they were up to in there. And furthermore, Susan, I wouldn't be the least bit surprised to learn that all four of them habitually smoked marijuana cigarettes...REEFERS.\" Cue the sound of a bong rip.
Marijuana (cannabis or bong) lung refers to the presence of large apical bullae in patients who regularly smoke marijuana. A definite causative link between smoking marijuana and bullous lung disease has not been established, and the association may just be coincidental.
Cannabis smoking can create respiratory problems. Vaporizers heat cannabis to release active cannabinoids, but remain cool enough to avoid the smoke and toxins associated with combustion. Vaporized cannabis should create fewer respiratory symptoms than smoked cannabis. We examined self-reported respiratory symptoms in participants who ranged in cigarette and cannabis use. Data from a large Internet sample revealed that the use of a vaporizer predicted fewer respiratory symptoms even when age, sex, cigarette smoking, and amount of cannabis used were taken into account. Age, sex, cigarettes, and amount of cannabis also had significant effects. The number of cigarettes smoked and amount of cannabis used interacted to create worse respiratory problems. 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
We sought to identify the impact of vaporizers on respiratory symptoms. In an effort to target frequent cannabis users, three organizations committed to reforming drug laws were asked to send a query to their mailing lists for participation in a survey. Participants responded to an email request and had a chance to win a cash prize. Approximately 9,000 people replied, but we focused on those who had used cannabis at least once in the previous month. (More details of the data collection appear in a paper addressing other aspects of this sample .) In an effort to minimize the impact of other sources of respiratory symptoms, only those respondents who did not have cystic fibrosis or asthma and had never inhaled other drugs (inhalants, heroin, methamphetamine, or crack cocaine) were included. Those who reported that their primary method of administration of cannabis was oral ingestion were also omitted, because eating the plant should have no smoke-inhalation-induced respiratory effects. 59ce067264
