Leafly explains that "dabs are concentrated doses of cannabis that are made by extracting THC and other cannabinoids using a solvent like butane or carbon dioxide, resulting in sticky oils also commonly referred to as wax, shatter, budder, and butane hash oil (BHO)." This oil is reportedly one of the most potent forms of weed, and "patients dealing with severe or chronic pain or extreme nausea report that dabbing can be one of the best ways to get immediate and effective relief," Leafly adds. The leftover nug will likely be rendered useless after the hair-straightener treatment, but hey — if it's wax you want, it's wax you'll get.
You can watch the technique yourself below.
Here's @gold_ash tutorial of the Rosin Technique. This is useful for those who only dab once in awhile or want to save a couple bucks. It's safe and you don't have to worry about harmful chemicals or anything exploding your face. All you need is a nug, hair straightener, and some parchment paper. (DO NOT USE WAX PAPER) Place the nug in the parchment paper and squeeze it with the hair straightener at the highest temperature for 8-10 seconds. Then collect the bits of oil with your dabber and dab away! You can still use the compressed nug to smoke so it won't go to waste. #rosintech #rosin #dab #dabs #marijuana #420 #cannabis
