Jul 14, The temperature settings on a vaporizer can result in different effects. Accuracy is another feature that vaporization offers that smoking blunts, Decarboxylation occurs with heat, and results in the removal of a carboxyl. Jul 28, Smoking cannabis flower is an age-old and highly effective way to Just remember the golden rule of cooking with cannabis: decarboxylation. can be loaded into a vape pen and used at home or discreetly whilst on-the-go. Aug 14, Decarboxylation is an important yet often misunderstood aspect of cannabis higher potency than traditional methods of consumption (i.e. smoking). . You can absolutely smoke and vape your cannabis after decarbing it!.
Decarboxylate. Smoke. Vape.
Higher-priced, battery-powered vaporizers use convection and conduction heating methods, eliminating the risk of burning yourself. Will you be vaping solo, or with others? Are you a daily smoker, or more intermittent? If you plan on having group vape sessions, a vaporizer with a larger capacity chamber like the DaVinci IQ would be better suited than something like the DynaVap line.
Some vapes only work with dry herb; others also have the capability to vaporize cannabis concentrates like shatter and wax. Combo vapes tend to cost a bit more due to their versatility. Unfortunately, not all vapes are created equal. There are many inferior knockoffs out there, so only purchase a vape from a reputable shop or website. Do NOT buy vaporizers from eBay. The auction site is filled with counterfeit vaporizers that could expose you to dangerous chemicals and other contaminants. Stick to reputable, trustworthy sellers.
Just want to get to vaping? Here are three great choices for portable vapes at three different price points. Sites like RetailMeNot often have codes to save you a bit of cash on your purchase. So there you have it: What is dry herb vaping? Why should you vape cannabis? Puffing a joint is like using a sledgehammer for sculpting, while vaping is like using a chisel. Both will get the job done, but the latter allows you to have fine-tuned control over your experience.
Dry herb vaporizers come in all shapes, sizes, skill levels and price ranges, but most portable vapes are small enough to easily fit in your pocket or purse. Vaping also leaves less of a cloud than combustion. A gift that keeps on giving: Vaping cannabis is so nice, you can use the bud twice! Already vaped bud AVB is dry, brittle and smells toasted.
How does dry herb vaping work? Green means go on the Fury 2 dry herb vaporizer. We have the temp cranked to burn off any alcohol left after cleaning. Your dry herb vape of choice see below for a few recommendations Your favorite strain s of cannabis the terpy the better A grinder A funnel or other loading tool, like a grinder pick or Lego shovel An airtight glass jar to store your AVB Isopropyl alcohol and cotton swabs for cleaning your vaporizer L to R: Tips for getting better draws from your dry herb vape Go for a fine grind: Generally, less is more here.
Packing your bud tightly in your vape limits the surface area exposed to the heating elements. That makes it harder for the hot air to reach those precious trichromes.
Stir the bud after a few draws: Dronabinol or tetrahydrocannabinol THC pills, ethanolic cannabis tinctures, oromucosal sprays or table vaporizing devices are available but other cannabinoids forms can be used. Inspired by the illegal practice of dabbing of butane hashish oil BHO , cannabinoids from cannabis were extracted with butane gas, and the resulting concentrate BHO was atomized with specific vaporizing devices.
The results showed that illegal cannavaping would be subjected to marginal development due to the poor solubility of BHO in commercial liquid refills especially those with high glycerin content. This prevents the manufacture of liquid refills with high BHO concentrations adopted by most recreational users of cannabis to feel the psychoactive effects more rapidly and extensively.
However, the electronic device marketed for therapeutic cannavaping should be carefully designed to minimize potential overheating and contaminant generation. The creativity of cannabis users leads to new methods of consumption. Although developments such as vaporizers, edible and liquid tinctures have become very popular alternatives to the traditionally smoked flower buds of cannabis, they show flaws in concentrations, contamination or efficiency over the day according to galenic forms 1.
By eliminating tobacco and increasing THC levels, these optimizations appear to be interesting improvements for the therapeutic use and delivery of cannabis. However, public health concerns remain because of the ease of preparation, more rapid THC delivery i. BHO is a viscous, sticky to hard, wax-like concentrate that contains mainly acid cannabinoids and terpenoids.
BHO is highly enriched in THC, and its concentration is typically 15 to 30 times higher than that found in flower buds 4. However, the literature is very scarce concerning BHO preparation and composition. Commonly, a dab of the dense oil is placed on the end of a glass or titanium rod that has been heated. If the dab has been previously decarboxylated, the flame from a lighter is sufficient to vaporize the BHO, but if the dab has not been decarboxylated, a blowtorch is used to maximize the decarboxylation of THC-A into its psychoactive form, THC, and to vaporize the BHO concentrate 1.
Nevertheless, the enormous growth and development of electronic cigarettes or e-cigarettes have enabled the development of electronic devices exclusively dedicated to direct dripping the liquid is dripped onto the bridge of the atomizer, instead of relying on the cartridge filler 9 and dabbing.
These devices are currently available on the Internet and cannabis derivatives shops. Furthermore, a profusion of recipes is available on the Internet to prepare liquid refills enriched with cannabinoids.
In this regard, BHO can be dissolved in the commercial liquids used to refill e-cigarettes, constituting an alternative to direct BHO dabbing. With the several thousand flavored liquids commercially available, flavors added to liquid refills can mask the overwhelming typical odor of cannabis and can make its vaping more discreet Indeed, concentrating cannabinoids implies a concentration of terpenoids and odorant compounds, which renders dabbing an easily detectable method of cannabis consumption for people exposed passively to cannavaping.
The regulations of European countries have recently registered positive concern with the therapeutic use of cannabinoids By November , a total of 23 states in the U. Nevertheless, the possibility of e-cigarette multiuse for cannavaping has arisen, whereas the carbonyls and volatile toxic compounds in the vapors of conventional e-cigarettes are still discussed 12 , 13 , 14 , Regular cannabis smokers will prefer e-cigarette aerosols with strong organoleptic qualities.
Moreover, the unpleasant flavors of liquid refills heated at such high settings could be hidden by the strong flavor of cannabis terpenoids.
Consequently, the investigations of e-cigarettes vapors should always consider carbonyls and volatile compounds monitoring. Although concerns about the generation of contaminants from glycerin and propylene glycol are well identified, other concerns that have received little attention until now include the potential for toxic effects from inhaled flavorings The goal of this study was to evaluate the efficiency of cannabis vaping using commercially available e-cigarettes as an alternative to marijuana smoking for therapeutic cannabis delivery.
The ease of manufacture of THC-enriched liquid refills for e-cigarettes and its misuses , the possibility of generating THC-enriched aerosols at sub-pyrolysis temperatures, and the formation of potentially toxic by-products, i.
The electrical settings of the e-cigarette and the choice of the value of the resistance are known to affect the amount and composition of the aerosol. The best compromise optimum power must be found between the value of the resistance and the battery voltage to generate the greatest amount of aerosol and THC and fewer toxic by-products. Overly high power can damage the coil and equipment and promote the formation of toxic compounds. The current measured through the coil was 1.
The stability of the current intensity indicated that the batteries could provide fairly constant 6. This value could have been underestimated because the sensor was not in direct contact with the metallic coil. Nevertheless, this recorded temperature was probably characteristic for the few milligrams of liquid atomized in one puff. It could be observed that the temperature increased until the current was turned off; therefore, the temperature could be greater given a longer puff Fig.
Therefore, the decarboxylation of THC-A with the type of e-cigarette used in our study was possible, albeit with poor performance. Thus, although the final temperature is sufficient for conversion, this refers only to the peak temperature which is probably reached at the end of the puff. However, if longer puffs could improve the decarboxylation rate of THC-A, they could also generate toxic contaminants mainly carbonyls and cause an unpleasant taste of the aerosol Influence of the decarboxylation conditions, estimation of the quantity of liquid refill consumption to reach a THC concentration of 1.
Bioavailability of vaped and smoked THC is supposed to be the same. The total recovery yield of THC in the mainstream smoke of the cannabis cigarette Design C reached 5. In contrast with e-cigarette vaping, a large amount of sidestream smoke was also formed and released into the exposure room.
However, the small amount of THC found in the mainstream smoke conformed with the THC concentrations found in the literature for cannabis cigarettes and with the daily dosage recommended for therapeutic cannabis administration: As a result, potentially to feel the same effects as with a cannabis cigarette delivering 3.
These data showed that vaping the desired concentrations of cannabinoids could be only achieved using concentrates such as decarboxylated BHO solutions as described in this work. The solubilization of crude, not unheated, BHO was difficult because of the presence of insoluble matter and fine plant fragments and impurities. Indeed, BHO concentrates are strongly lipophilic, while liquids refills are very hydrophilic, and both are highly viscous.
Vortex-mixing of the decarboxylated BHO resulted in more efficient solubilization in liquid refills. It was hypothesized that the main source of variation was constituted by the partial solubilization of BHO, the formation of an emulsion with many droplets and the absorption of BHO on the walls or bottom of the container. However, this soft decarboxylation has rarely been described on Web fora or in the underground literature.
However, insoluble matter and some fine particulates in the suspension were still noticeable. PG is less viscous than glycerin and a better emulsifier and solvent. In contrast with glycerin, it is miscible with several apolar solvents.
Nevertheless, omission of glycerin greatly reduced the formation of visible white aerosol and could unbalance the organoleptic qualities of the aerosol taste. However, the combination between the intensity and duration of coil heating cannot be optimal with the standard settings of e-cigarettes.
This thermal treatment should therefore be undertaken before BHO mixing with the vaping liquid. Better yields were also observed with soft decarboxylation conditions i. The quantities of cannabinoids-enriched liquid refills that should be vaped for their therapeutic or alleged beneficial effects were estimated from THC concentrations present in the liquid refill Table 1 and in condensed vapor Table 2.
To this end, a minimal dose of 1. Indeed, this quantity has been reported as the lowest effective dose able to induce some psychoactive effects, when injected intravenously 25 , Similar doses have been reported for therapeutic administration of THC.
For instance, oral THC doses from 2. A low dose of cannabis 1. However, achieving a clear and homogenous solution will be difficult due to flaws in solubility. We can also speculate that some users will experiment with e-cigarettes for recreational reasons. Indeed, the macroscopic and microscopic observations, as well as the composition of the diluted decarboxylated BHO in pure PG, confirmed this assumption: Experimental results, obtained from our vaping setup, indicated that much higher amounts of liquid refill would be required to produce the same effects of cannabis as expected with regard to theoretical simulation discussed above Table 2.
Consequently, the choice of the decarboxylation procedure had a limited effect on the yield and concentration of THC found in the aerosol. As a result, the vaporization yield of THC in the selected experimental setup was much lower than expected. To improve the efficiency of cannabinoids vaporization, i. These conditions were achieved with the maximal settings combination highest power and voltage of the e-cigarette chosen for the study.
These settings should increase the decarboxylation rate of acid-cannabinoids but should also simultaneously produce more contaminants. Indeed, the strong flavor of the terpenoids compounds of cannabinoids mixtures can mask the bad taste of commercial liquid refills vaped at high settings. The results concerning carbonyls and VOCs concentrations found in the vapors generated from liquid refill mixtures are compiled in Table 3. Only two carbonyls were detected in significant amounts formaldehyde and acetaldehyde and only PG as a VOC.
The carbonyls amounts measured were similar to those previously reported formaldehyde: Nevertheless, the acetaldehyde concentrations appeared to be higher in our study, probably likely because of the differences in device, settings and liquid refill compositions. Moreover, we could show a direct correlation between the e-cigarette settings and the concentrations of carbonyls: Higher acetaldehyde amounts were obtained after vaping BHO mixtures dissolved in commercial liquid refills or pure PG, rather than after vaping the commercial liquid refill alone.
As expected, PG was detected in the vapors of commercial liquid refills spiked with or without cannabinoids standards made of pure PG or of commercial liquid refill composition. No VOCs were detected in the vapors of the different liquid refills commercial, cannabinoids standards and BHO mixtures except for PG, whereas acetone, benzene, toluene, ethylbenzene, p-xylene, styrene and phenolic compounds were present in tobacco cigarettes and real cannabis cigarettes Table 4. However, the smoke of regular cannabis cigarettes seems to contain less acetone and styrene and more phenolic compounds than that of regular tobacco cigarettes.
The combustion and inhalation of cannabis cigarettes is generally considered an inappropriate method for the therapeutic administration of cannabis. Safer and healthier alternatives for consuming cannabis have been proposed to minimize the risks associated with the inhalation of toxic pyrolytic by-products. Vaporization conducted at less than combustion temperatures is one of the best recommended alternative methods to cannabis smoking.
A vaporizer heats the cannabis plant material at a moderate temperature, causing the active cannabinoids to evaporate into an aerosol that contains far fewer harmful components.
To this end, table vaporizers are commercially available e. Portable, robust, low-weight, pocket pen-vaporizers are now available for nicotine inhalation. Many of these portable vaporizers can be adapted for the consumption of cannabis extracts. E-cigarettes of different brands and of varied designs could also be used for this purpose.
To this end, e-cigarettes equipped with various special vaporization chambers can be used to deliver a therapeutic dose of cannabinoids. Roughly three types of devices exist on the market: Vaporization of ready-to-use, pre-packaged liquids, having a certified composition and concentration, appears to be the most convenient and easiest option for therapeutic use by patients. The manufacture of cannabinoids-enriched e-liquids was found to be quite difficult, and achieving a homogenous and stable mixture of high-potency waxy residues of cannabis extracts e.
Preparation of liquids with higher BHO content could be of significant interest for therapeutic cannabinoids delivery as an alternative to cannabis smoking, especially for practical reasons. However, higher BHO concentrations can lead to cannabinoids solubility problems in the liquid refills.
Optimization research, in particular with PG, should be undertaken to determine the best liquid refill composition offering a certified cannabinoids concentrations in the liquid and, if possible, in the vapor. Pure PG and other blends of glycols e. To feel the first psychoactive effects sooner, increases in BHO levels and THC concentrations in the vaped solution are required, but due to the inconvenience in its manufacture and final organoleptic properties, such goals will be made more difficult and less appealing.
Moreover, the most common commercial liquid refills containing PG and glycerin in various proportions and often some water are not the best solvents to solubilize BHO. Pure PG is a better solvent. Liquid refill choice is important to guaranteeing fair BHO solubilization and THC availability in the vapor, and it requires low glycerin content. In contrast, the heating of glycerin can lead to an increase in acrolein, another toxic contaminant not reported in our experiments because of the liquid refill composition used with no or low glycerin content.
Consequently, the preparation of BHO and the making of a homogenous homemade liquid refills containing high proportions of BHO, with a pleasant taste and a fair level of glycerin, appear complex and unappealing to recreational and addicted cannabis consumers.
This gentle method of THC delivery could be of great importance in the context of finding new administration methods for medical cannabis. However, because the manual settings of more modern e-cigarettes can be freely adjusted by the vaper, unsafe settings can be selected to increase the efficiency of BHO and THC vaporization. It is therefore important to monitor carbonyls and VOCs contaminants to keep these potentially toxic residues in negligible quantities.
If the vaping of these liquid refills at these high settings produced unpleasant flavors due to liquid burning, these off-flavors could be masked by the fragrance of cannabis terpenoids. However, these high settings were correlated with the formation of formaldehyde and acetaldehyde content in not negligible but similar amounts to those already determined with commercial liquid refills and e-cigarettes. Therefore, we advocate testing for the presence of toxic contaminants when optimizing the vaporization of cannabinoids-enriched liquid refills.
In particular, we recommend determining the levels of carbonyls and VOCs contaminants, although the first results obtained at high settings did not seem to show abnormalities. The maximal levels of power and voltage delivered by the e-cigarette were chosen to maximize the contaminants generation and the recovery of cannabinoids in the vapor. However, these settings could be ignored by vapers because of organoleptic flaws. We used cannabinoid standards and BHO, a viscous, amber-colored, waxy cannabis concentrate, as raw cannabinoids material, but other sources, such as tinctures or macerated preparations, could be used by vapers also, although irritating ethanolic vapors could deter some users.
This study specifically focused on homemade cannabinoids enriched liquid refills with BHO, but illegal liquid solutions of synthetic cannabinoids are currently available on the Internet 6 , The most dangerous aspect of BHO concerns its preparation.
Several reports of gas explosions while attempting butane extraction have been posted on the Internet. Use of a fume hood is mandatory in laboratory settings.
Inhalation of traces of butane appears to pose no major health risk, although death reports correlated with butane inhalation have concerned the abuse of gas fuel among drug addicts 37 , Supercritical CO 2 extraction is very likely more appropriate for preparing cannabis concentrates.
CO 2 toxicity is lower, and the risk of explosion is far less. In the calculations, bioavailability of vaped and smoked THC is supposed to be the same. However, measurement of cannabinoids compounds in the aerosol of e-cigarettes and smoke of cannabis cigarettes does not necessarily imply equivalent absorption to the bloodstream.
