Researchers Create Smokeless Marijunana Device

A smokeless marijuana-vaporizing device delivers the same active therapeutic chemical as smoking marijuana, but without the harmful toxins, says a U.S. study.
A University of California, San Francisco research team looked at the effectiveness of a device that heats marijuana to a temperature of between 180 and 200 degrees C -- just short of combustion. Eighteen people were enrolled as inpatients for six days under supervision in the General Clinical Research Center at San Francisco General Hospital Medical Center.
The plasma concentrations of the active ingredient delta-9-tertrahydrocannibinol, or THC, were comparable at all strengths of marijuana between smoking and vaporization, according to the study published in the online issue of the journal Clinical Pharmacology and Therapeutics.
Using carbon monoxide as an indicator, there was virtually no exposure to harmful combustion products using the vaporizing device, study co-author Dr. Neal L. Benowitz, said in a statement.
Since it replicates smoking's efficiency at producing the desired THC effect using smaller amounts of THC, as opposed to pill forms, this device has great potential for improving the therapeutic utility of THC.

This study was funded by the National Institue of Health.
We all know that government funded studies on the effects of marijuana are nothing but biased propaganda.

uuhhh.... did you read what he posted? And have you ever used a vaporizer? The article was an accurate report of a vape, and calling it propoganda merely because it was sponsored by the Gov. is tremendously shorsighted.

vaporizers are alright, i just dont like them myself, i like getting full flavor when smoking pot, i stick to bowls myself, even though i know its still giving me some harmful chemicals, the taste is one of the main reasons i smoke it and smoking through a vaporizer tastes like inhaling soup steam or something, just not for me. great study though.

How do you become a guinea pig for that experiment.
US: Hi, we're going to pay you six hundred dollars to smoke pot from a vaporizer. The only thing is that you have to log how your throat feels and how high you get.

Vaporizing is the only method that has given me the full taste of the bud I'm smoking at the time. You're not burning anything and it just tastes like straight bud.

This article demonstrates the epitome of the government's beaurocratic system being a shambles, moving developmentally at a speed comparible to a land bound hippopotamus, with a broken back leg; the hippopotamus reaching it's destination meaning total understanding of the truth, and the broken back leg symbolizing the hand of special interest and outside control holding the truth back.
How can scientists dare create their own, crappy vaporizer, when the best vaporizer, Volcano, is already at hand? That strikes me as completely irrational and boring.
I'm high.

I bet it was a Volcano. They probably avoided branding the article to retain some credibility on an already taboo subject. Researchers??? More like Storz & Bickels' inventors?

Okay, I must admit that my first post was entirely sarcastic.
My point was that the National Institute of Health (which funded the study) is the same government institution that funds manyof the other "evil" studies on marijuana claiming it may have detrimental effects.
Research (especially human research) will always have inherent weaknesses. However, a particula weakness (in any study) doesn't necessarily indicate it is "biased evil propaganda".
For instance, in this particular study I would be curious to see how many exposures each participant was subject to. It will also (more than likely) list the source of the vaporizer if it was commercially purchased.

Marijuana Vaporizer Provides Same Level Of THC, Fewer Toxins, Study Shows
Science Daily — A smokeless cannabis-vaporizing device delivers the same level of active therapeutic chemical and produces the same biological effect as smoking cannabis, but without the harmful toxins, according to University of California San Francisco researchers.
Results of a UCSF study, which focuses on delivery of the active ingredient delta-9-tertrahydrocannibinol, or THC, are reported in the online issue of the journal "Clinical Pharmacology and Therapeutics."
"We showed in a recent paper in the journal 'Neurology' that smoked cannabis can alleviate the chronic pain caused by HIV-related neuropathy, but a concern was expressed that smoking cannabis was not safe. This study demonstrates an alternative method that gives patients the same effects and allows controlled dosing but without inhalation of the toxic products in smoke," said study lead author Donald I. Abrams, MD, UCSF professor of clinical medicine.
The research team looked at the effectiveness of a device that heats cannabis to a temperature between 180 and 200 degrees C, just short of combustion, which occurs at 230 degrees C. Eighteen individuals were enrolled as inpatients for six days under supervision in the General Clinical Research Center at San Francisco General Hospital Medical Center.
Under the study protocol, the participants received on different days three different strengths of cannabis by two delivery methods--smoking or vaporization--three times a day.
Plasma concentrations of THC were measured along with the exhaled levels of carbon monoxide, or CO. A toxic gas, CO served as a marker for the many other combustion-generated toxins inhaled when smoking. The plasma concentrations of THC were comparable at all strengths of cannabis between smoking and vaporization. Smoking increased CO levels as expected, but there was little or no increase in CO levels after inhaling from the vaporizer, according to Abrams.
"Using CO as an indicator, there was virtually no exposure to harmful combustion products using the vaporizing device. Since it replicates smoking's efficiency at producing the desired THC effect using smaller amounts of the active ingredient as opposed to pill forms, this device has great potential for improving the therapeutic utility of THC," said study co-author Neal L. Benowitz, MD, UCSF professor of medicine, psychiatry and biopharmaceutical sciences. He added that pills tend to provide patients with more THC than they need for optimal therapeutic effect and increase side effects.
Patients rated the "high" they experienced from both smoking and vaporization and there was no difference between the two methods by patient self-report of the effect, according to study findings. In addition, patients were asked which method they preferred.
"By a significant majority, patients preferred vaporization to smoking, choosing the route of delivery with the fewest side effects and greatest efficiency," said Benowitz.
Co-authors include Cheryl A. Jay, MD, UCSF neurology; and Starley B. Shade, MPH; Hector Vizoso, RN; and Mary Ellen Kelly, MPH, UCSF Positive Health Program at San Francisco General Hospital Medical Center.
The study was funded by the University of California's Center for Medicinal Cannabis Research.

In any event, the original article's title is misleading, the authors didn't claim to invent anything. They simply looked at some of the properties between regualr smoking and vaporization.
They did in fact, use a Volcano Vaporizer.

Have you used a Volcano? Or some home made POS lightbulb bullshit?
I have no idea how you claim to enjoy "full flavor" when burning weed REDUCES the flavor. The flame burns away most of the flavor... You are tasting tar and ash with some flavor from the parts of the bowl that didn't get napalmed.
With a perfect Volcano hit, you can taste and smell the true essence of the herb... with all the essential oils and shit NOT completely incinerated into cancerous ash.
Your statement is highly illogical.
At least you use a bowl... they are still better than joints and WAY better than blunts if you REALLY enjoy the natural flavor of bud.

Ha! That's like someone who hates beer saying that bud light is the best beer because it has no flavor and tastes like garden hose piss-water.

Thanks for telling us how we should smoke our weed. It's a good thing we have experts like you around to make sure we don't screw up and actually get a nice thick rich hit.

I prefer the volcano to anything I've smoked from. It's smoother healthier and it tastes better. Plus, I don't have phlem. Best way to 'smoke for a non-smoker, imo.
