OK, we shouldn’t have to tell you to never smoke anything that smells like piss , but if your weed smells like an athlete’s drawers or the inside of a gas station’s urinal, you’re probably dealing with moldy or mildewy buds . Mold and mildew are issues with modern cannabis cultivations, due to the non-stop demand for new products and lack of sufficient airflow in many indoor grows. Overly moist conditions often lead to spoiled weed, too.
Although moldy weed can be spotted by the naked eye, being able to see physical traces of mold or mildew isn’t always a sure-fire test. That’s due to mold and mildew reproducing through spores, and your nugs can be infected without ever sprouting the tell-tale white moldy fuzz. So give your weed an extra whiff for good measure, and if it smells dank in all the wrong ways. Smelling burnt hair before or after you've blazed your bud could be a sign that there are excess chemical residues on or in the flower. Although a recent report claimed that weed smokers couldn’t tell the difference between properly flushed nugs and nugs that were never flushed (in fact, they seemed to prefer the non-flushed weed, oddly enough), it’s possible you’re smelling weird shit because a cultivator went overboard with the growth nutrients. It’s also possible that there’s actual hair (human or animal) in your weed, especially if you bought it from some shady back-alley dealer. While we rarely associate the smell of a passing skunk with anything positive, it’s always a good thing when it comes to weed. So-called “skunk weed" gets its characteristic scent from compounds called thiols, which contain sulfur, the chemical that makes match heads smell gassy.
Cannabis naturally produces some thiols, namely propyl mercaptan, benzyl mercaptan, butanethiol, and ethanethio. So if your weed smells like Pepe Le Pew, that's actually a good thing. Good: It Smells Like Fresh Cut Fruit, Flowers, or Ground Spices. Terpenes in weed are responsible for most of the scents you’ll notice in your weed. Many terpenes that are found in fruits such as lemons , strawberries, and blueberries pop up in cannabis, too, which is why some strains smell like oranges while others carry hints of banana peels. Other terpenes give weed its spicy notes, with scents reminiscent of black peppercorns, cloves, or even cinnamon. Next to skunk, the smell of pine is probably the biggest indicator that you’ve got quality flower in front of your face. Weed's pine scent comes from a terpene called pinene, and yes, it’s the same terpene found in pine needles and pine sap. Alright, so now that you know what you’re looking for (and not lookin for), how should you approach the physical act of smelling your weed? The most effective way to take in a bud’s full bouquet is by gently squeezing the bud first, then hold it up to your nose. Squeezing the bud releases terpenes and gases from the trichomes , where most of the plant’s terpenes and cannabinoids are produced. However, squeezing the bud will damage the trichomes, so keep that in mind if you’re sniffing a nug that’s also supposed to be on display. If you’re smelling live weed plants, just run your fingertips over the flowers. But again, as with squeezing the buds, ask before trying this method, since touching live plants can introduce them to molds, mildews, and pests. If you’re trying to subject some dispensary weed to a smell test, there’s a good chance they won’t let you touch the buds. That’s due to health reasons and because too many asshats will steal weed this way . If you can, cup your hands over the container to trap in the smells, then breathe in. If you can’t touch the container, simply wave your hand over the top, so whatever scents are wafting off will fly into your nose. Even the most novice cannabis consumer will eventually be able to tell good weed apart from bad weed just by smell alone. It takes a little time and a lot of patience, so give yourself room to breathe (and learn) as you train your ole factory to detect what quality cannabis smell like. The GDS Essential guide to vaping science Dr Adam R Winstock Founder Global Drug survey and Consultant Psychiatrist Guy Jones Technical Lead Reagent Tests UK. The rise in vape technology is not the first time that scientific innovation has changed the way we use drugs. The invention of the hypodermic needle allowed purified morphine and cocaine extracted from their natural origins (the opium poppy and coca leaf respectively) to be delivered with previously unimaginable efficiency and dosing accuracy. The drive for both extraction and purification of the drugs as well as the development of the needle was not to intoxicate but to medicate. Western medicine relies heavily on being able to replicate dosing regimens that require knowing exactly how much of a particular drug you are giving to optimise the balance between therapeutic benefit and harm.
A bit of heroin kills your pain, too much kills you.
While the drive behind vaping has been in part public heath (the driver behind e-cigarettes) and medicinal (offering medical cannabis users a way of using cannabis concentrates such as Butane Hash Oil without having to smoke weed is great) , there’s no doubt that vaping cannabis concentrates offer cannabis users another way of getting high. It also offers huge business opportunities for new vape tech companies (the profit potential of which often results in them being snapped up by the big tobacco companies).
