THC applied to the skin can enter the bloodstream, but whether it does—and how much gets through—depends heavily on the product. Conventional cannabis creams and balms often produce little or no detectable systemic THC under studied conditions. Products specifically engineered…
A major new analysis of controlled human cannabis studies is challenging one of the most persistent assumptions surrounding cannabidiol: that adding CBD to THC will necessarily weaken THC’s effects. Researchers reviewing 14 clinical experiments found that co-administering CBD with the…
Human breast milk contains naturally occurring compounds that interact with the body’s endocannabinoid system, but describing them simply as “cannabinoids in breast milk” can easily create confusion. The compounds found naturally in milk are endocannabinoids—lipid signaling molecules produced by the…
Kief is the loose, powdery material made primarily from the resin-producing glandular trichomes that naturally cover mature cannabis flowers and nearby small leaves. Under magnification, these trichomes resemble tiny stalks topped by rounded resin heads. They are not simply decorative…
Although cannabis allergy remains much less studied than allergies to foods, pets, pollen, or medications, physicians have documented reactions ranging from itchy eyes and hives to asthma and, rarely, life-threatening anaphylaxis. Exposure does not have to involve smoking. Allergic reactions…
Cannabis edibles can expire, but two different clocks are running at the same time. The food itself can lose freshness or eventually become unsafe, while the cannabinoids inside it can slowly degrade. A THC gummy may remain physically edible after…
Live resin and distillate can both deliver concentrated THC, yet they represent almost opposite philosophies of cannabis processing. Live resin is designed to preserve a broader chemical snapshot of freshly harvested cannabis, especially its volatile aromatic compounds. Distillate takes the…
Red eyes are one of the most recognizable short-term effects of cannabis. After THC takes effect, the whites of the eyes may look pink or bloodshot, small vessels become easier to see, and the eyes may feel dry or heavy.…
Rosin and resin are both cannabis concentrates, but the words do not describe the same type of product. Rosin is a specific solventless extract produced with heat and mechanical pressure. Resin is a broader term that can refer to the…
Cannabis edibles are known for effects that can be stronger, longer-lasting, and less predictable than inhaled cannabis. Yet some consumers report that gummies, brownies, capsules, and infused drinks do almost nothing, even when smoking or vaping produces an obvious effect.…
Cannabis acts on one of the brain’s most widely distributed signaling systems, which is why its effects can reach perception, memory, mood, appetite, pain, movement, sleep, and reward. Most neuroscience has focused on delta-9-tetrahydrocannabinol, or THC, and cannabidiol, or CBD.…
Cannabis has been linked with creativity for generations. Musicians, writers, painters, comedians, and other artists have described marijuana as a way to escape routine thinking, notice unusual details, or become absorbed in creating. Popular culture has reinforced the idea that…
