The plenum vaporizer works by accurately splitting the incoming gas into two streams. One of these streams passes straight through the vaporizer in the bypass channel. The other is diverted into the vaporising chamber. Gas in the vaporising chamber becomes fully saturated with volatile anaesthetic vapour. This gas is then mixed with the gas in the bypass channel before leaving the vaporizer.
Hi Amanda. I wouldn’t get the iStick 50W, as it had some autofiring issues. Any of the other three are solid choices. The Subox Mini has a larger tank than the Nano, but the Nano is slightly sleeker in terms of the design of the box itself. The Evic Mini looks great as well and you can’t go wrong with any of those three you mentioned.
A 2009 study by the U.S. Food and Drug Administration found that the e-cigarettes studied “contained detectable levels of known carcinogens and toxic chemicals to which users could potentially be exposed.”

The liquid or “smoke juice” used in most electronic cigarettes is made up of four main ingredients: propylene glycol, vegetable glycerin, nicotine and added flavoring. These ingredients are almost always listed on the label, but what happens after the liquid is vaporized and inhaled? Although there’s plenty of information about what’s inside e-liquid, research is finally shedding some light on the vapor as well. Studies report what many of us have suspected all along, that it’s significantly less harmful than tobacco smoke and poses virtually no health risks to users or bystanders.
Vaporizers can range anywhere from $10 to $600. As a rule of thumb, the more expensive a unit is, the more quality you can expect from it. So if it’s in your budget, go for the gold. That said, there are plenty of affordable options available. Just remember, investing in a more expensive unit will pay off in the long run because it’s less likely that you’ll need to replace it.

Nicotine is an optional addition, and there’s little to worry about here. First of all, nicotine in vapes doesn’t come with all the unhealthy side effects of a standard nicotine cigarette. Second of all, the nicotine in our e-juice is always pharmaceutical grade, pure nicotine.
I just got out of hospital, having Iscemic Colitis. My illness was caused by smoking for almost 40 years. My surgeon thought it was FANTASTIC I had been able to kick my nicotine habit. He advised me to try to get down to 0% nicotine. So I am trying! Thanks for the enlightening post. I hope all my family and friends will get off my back to quit vaping! I like it!!!
A typical volatile agent, isoflurane, has a saturated vapour pressure of 32kPa (about 1/3 of an atmosphere). This means that the gas mixture leaving the vaporising chamber has a partial pressure of isoflurane of 32kPa. At sea-level (atmospheric pressure is about 101kPa), this equates conveniently to a concentration of 32%. However, the output of the vaporizer is typically set at 1–2%, which means that only a very small proportion of the fresh gas needs to be diverted through the vaporising chamber (this proportion is known as the splitting ratio). It can also be seen that a plenum vaporizer can only work one way round: if it is connected in reverse, much larger volumes of gas enter the vaporising chamber, and therefore potentially toxic or lethal concentrations of vapour may be delivered. (Technically, although the dial of the vaporizer is calibrated in volume percent (e.g. 2%), what it actually delivers is a partial pressure of anaesthetic agent (e.g. 2kPa)).

Recently there has been a new type of oil called CBD. This stuff is also made from cannabis, and is completely legal, since it does not contain the active compound THC. CBD is perfect for those who want to reap the medicinal benefits of cannabis, but don’t want to get high.
E-juice generally has 2-5 ingredients. The base is either straight Vegetable Glycerin or a mix of Vegetable Glycerin and Propylene Glycol. These two ingredients are usually shortened to VG and PG, so that’s that it refers to when something is a high VG blend or 100% VG, to name a few examples. When vape juice says 50/50, that means the base is half VG and half PG.

” check out our article on “What is a box mod?””…putting that without putting the link isn’t very helpful. Still don’t exactly what one is and don’t feel like searching this site until I find the article.

Dry herbs have been used for centuries for meditation, relaxation and medicinal purposes. Certain flowers and herbs can be dried and crushed and then inserted into a vape pen that is capable of vaping them. The vape pen chamber will heat up the dry herbs which will release a vapor which can be inhaled. Certain flowers and herbs have different aromatherapy properties.

Its convection heating technology delivers amazing vapor volume and tremendous flavor from your plant material, and its compact size makes it a perfect choice for those with an active lifestyle.
But there undoubtedly needs to be more research! Electronic cigarettes have only been around for a few years, so the biggest thing we’re lacking is LONG-TERM STUDIES showing the ongoing impacts of inhaling nicotine vapor. This will take more time and money, but it’s definitely coming. If past studies are any indication, it will continue to support the fact that e-cigs are much safer than tobacco… so bring it on!
The drawover vaporizer is driven by negative pressure developed by the patient, and must therefore have a low resistance to gas flow. Its performance depends on the minute volume of the patient: its output drops with increasing minute ventilation.

I use the Joy tech Cuboid, TFV4 octuplet coil, with dual LG 18650’s and it’s fantastic. The only problem is that the Cuboid has a 25amp capacitor built in to the firmware, so you can’t get an actual 200w with it… Unless someone else has a way, or hopefully joytech addresses this issue. But none the less, I use my setup at 100w, with the coil at 0.19ohms, and I get pretty hearty cloud and flavor.
When it comes to vaporizers, the length of the warranty can vary quite a bit. Generally, desktop vaporizers have the longest warranty, as they are intended to stay in one spot.

Be certain that the terms of the warranty are well understood prior to making a purchase decision.
