What's the difference between marijuana, cannabis? 4/20 terms to know.

Yahoo17-04-2025
Marijuana − medical and recreational − is legal throughout more than half of the United States, and for some looking to familiarize themselves with the plant and its effects, learning all of the associated terminology may feel daunting.
There's marijuana, cannabis, hemp and then there's Delta 8, 9 and 10. What are the differences, and what should new (and even veteran) users know before toking up?
As the unofficial weed holiday 4/20 (April 20) rolls around − no pun intended − here are some key pot terms to be familiar with.
Marijuana encompasses a broad range of products derived from the Cannabis sativa plant that contain the highest levels of tetrahydrocannabinol, more commonly known as THC.
Consuming marijuana, whether that be by smoking it, eating it in edible form or drinking it as a tincture, can have intoxicating effects and can trigger changes in mood or thoughts.

Under U.S. federal law, marijuana is classified as a Schedule I drug. This category also includes heroin, LSD, methamphetamines and peyote.
Marijuana was classified as a Schedule 1 drug with the establishment of the Controlled Substances Act in 1970.
Despite often being used interchangeably, marijuana and cannabis are not the same.
Cannabis refers to all of the products derived from the Cannabis sativa plant, according to the National Center for Complementary and Integrative Health. Marijuana refers to the specific products from the Cannabis sativa plant that contain substantial amounts of THC.
Tetrahydrocannabinol is the substance found within the Cannabis sativa plant that is primarily responsible for marijuana's psychological effects on a user.
Cannabinoids are the different chemicals found within the Cannabis sativa plant. There are more than 100 cannabinoids, according to the Alcohol and Drug Foundation, but the most common are THC and cannabidiol, or CBD.
Cannabidiol, more commonly known as CBD, is a chemical compound that can be found in both the Cannabis sativa and hemp plants. Under U.S. federal law, CBD is legal.
CBD does not contain THC, so it is not impairing, meaning it does not cause a user to get "high," or have psychoactive effects, according to the Centers for Disease Control and Prevention (CDC).
To date, the Food and Drug Administration has only approved one CBD product, a prescription oil called Epidiolex, which is used to treat seizures.
Delta 8, Delta 9 and Delta 10 are three of the more than 100 cannabinoids that exist.
Under federal law, Delta 8 and Delta 10 are legal for consumer purchase and usage. Delta 9 is not legal under federal law. States are permitted to write their own legislation about Delta 9 possession, consumption and distribution. Debates about the legalization of medical and recreational marijuana largely revolve around Delta 9.
Delta 9 is the most abundant form of THC found in the Cannabis sativa plant, according to Healthline. Delta 9 also produces the most psychoactive effects and can be used for a variety of reasons, including to help with anxiety, insomnia, low appetite, muscle pain and nausea.
Delta 8 and Delta 10 are both extracted from hemp-derived CBD.
Often referred to as "marijuana-lite" or "diet weed," Delta 8 is commonly used to calm nausea, boost appetite, ease pain, boost mental health and prevent vomiting during cancer treatments, according to WebMD.
Delta 10 has a lower THC potency than Delta 8 or Delta 10, meaning users typically experience less psychoactive effects.
All three cannabinoids can show up on a drug test.
Synthetic marijuana is lab-made marijuana and may be referred to as "Spice" or "K2." Synthetic marijuana is often sprayed onto dried plant material to make it smokeable. It can also be sold as a liquid to use in vapes.
Over the years, the federal government has banned several different types of synthetic marijuana, as the lab-made products can lead to severe illness and even death. Negative symptoms may include irritability, confusion, hallucinations, seizures, sleepiness, breathing problems, heart attacks, kidney failure and muscle damage, according to the CDC.
Because synthetic marijuana isn't regulated, there are no standards for its production, packaging or selling.
Cannabinol, or CBN, is a different type of cannabinoid found in the Cannabis sativa plant. When THC components break down, a less potent cannabinoid called CBN emerges, according to WebMD. CBN is about 25% as effective as THC. Less research has been done on CBN, but it does contain more THC than CBD, so it can produce mild psychoactive effects. CBN is largely used to relieve sleeping conditions like insomnia, WebMD states.
Marijuana and hemp can be used interchangeably, as they are the same species, according to Healthline. The difference comes from the amount of THC they both contain.
Healthline reports that hemp contains 0.3% or less THC by dry weight, so because the THC level is so low, it is unlikely that a user will get high.
Hemp, in addition to its medical and beauty uses, can also be used for commercial and industrial purposes, like rope, clothing, paper, bioplastics and biofuel.
Hashish, more commonly referred to as just "hash," is made from the resin of the Cannabis sativa plant. It is typically dried and pressed into blocks to be smoked or eaten, according to Partnership to End Addiction.
Edibles are marijuana-infused products that a user can eat or drink. Cookies, cakes, brownies, gummy candies and soft drinks are common edibles.

Doctors divided over new diet trend that has babies licking butter and gumming ribeye steak

Some parents are swapping puréed fruits and vegetables, oatmeal and yogurt for butter, bone broth, sardines and chicken liver as part of a controversial new "carnivore baby" trend – but experts are urging caution. As carnivore and protein-packed diets gain popularity among adults, many of whom are rejecting ultra-processed foods, some are passing them on to their kids. Some doctors are even sharing that they feed their babies meat-forward meals, The Wall Street Journal recently reported. Facebook groups are catering to carnivore families and parents are sharing tips on school lunches – rotisserie chicken, pork rinds and hard-boiled eggs among them. Meanwhile, others seek insight on trying to conceive while eating only meat. Dariya Quenneville, a mother in Ontario, Canada, told the publication that she started feeding her daughter raw egg yolks and puréed chicken liver as soon as she could eat solid foods and then moved on to sardines, bone broth ice pops, leg of lamb, beef heart and tongue. Lorraine Bonkowski, a registered dietitian from Michigan, and her one-year-old daughter are both on carnivore diets, Bonkowski told The Wall Street Journal. The little girl licks butter off a spoon, gets a bottle full of bone broth and uses her four teeth to gum ribeye steak. Bonkowski said she introduced fruit to her daughter's diet because her baby was getting constipated from all the meat. The Centers for Disease Control and Prevention (CDC) recommends feeding children over 12 months a variety of fruits, vegetables, whole grains, proteins and dairy products. While the carnivore trend has been firing up – U.S. Health and Human Services (HHS) Secretary Robert F. Kennedy Jr. recently shared that he follows it – others have been pushing it for years. In 2021, Dr. Robert Cywes, a Florida-based pediatrician, and his wife, Janae, said in a YouTube video that they started giving their son meat at 4 months old. His first real meal, they said, was a ribeye steak. "From a functional perspective, from a milestone perspective, he's right on target," Cywes claimed at the time. Dr. Shawn Baker, the Washington-based author of the book "The Carnivore Diet," boasted in a YouTube video last year that his baby ate a carnivore diet for six months, was walking at 10 months old and grew to be "strong and tall." "The first food for a baby, when it was ready to wean off the breast, was meat." Some doctors claim the practice has been used for centuries. "This is actually the original way that humans fed their babies 100 years ago, 500 years ago, 5,000 years ago," Dr. Ken Berry, a family physician in Tennessee, told Fox News' Dana Perino on "America's Newsroom." "The first food for a baby, when it was ready to wean off the breast, was meat … gnawing on a bone," Berry said. Meat ensures that babies get certain nutrients, vitamins, minerals, fatty acids and amino acids, he added, slamming puffs and other kids' snacks as "junk." However, Berry did recommend moderation by pairing meat with whole foods like berries. Fox News' senior medical analyst Dr. Marc Siegel said introducing kids to meat gets them plenty of protein and iron, yet without fruits and vegetables, the diet can become an "addiction." "It's a high-inflammation diet, which means later on, when you get to be an adult, you end up with heart disease, you end up with cancer, you end up with diabetes and you end up with obesity," Siegel said on "The Faulkner Focus." "This is a very bad diet to get addicted to as a kid," he said. Lauren Manaker, a registered dietitian nutritionist and mom in South Carolina, told Fox News Digital that while the carnivore diet provides "many options" that are "fantastic for babies," she said it "isn't ideal for little ones." "Babies need a variety of nutrients to grow and thrive, and a diet that cuts out or limits plant-based foods like fruits, veggies and grains can leave some big nutritional gaps," she cautioned.

Don't reschedule marijuana — it's not a safe substance

Don't reschedule marijuana — it's not a safe substance

President Trump is reportedly considering rescheduling marijuana from Schedule I to Schedule III under the Controlled Substances Act, which would significantly liberalize the rules that currently regulated it. Former U.S. Attorney and Congressman Bob Barr recently argued in The Hill that Trump should go ahead and do it. But although his proposal is framed as a pragmatic reform, it overlooks critical scientific evidence and public health risks. A more thorough examination reveals that rescheduling marijuana would be a dangerous misstep — one that prioritizes corporate interests over the well-being of society. The most authoritative federal review of cannabis research comes from the 2017 National Academies of Sciences Report, which identified only three medical conditions with substantial evidence supporting cannabis efficacy: chronic pain in adults, chemotherapy-induced nausea and vomiting, and spasticity symptoms in multiple sclerosis. Notably, conditions like post-traumatic stress disorder were classified as having only 'limited evidence,' meaning cannabis cannot be conclusively deemed an effective treatment. This directly contradicts claims that marijuana is a proven remedy for PTSD. In fact, the 2021 Veterans Affairs and Department of Defense Clinical Practice Guidelines explicitly reject cannabis for PTSD due to insufficient evidence and potential harm. Another critical issue is the dramatic rise in THC potency in marijuana due to bioengineering, a trend well-documented by the University of Mississippi's long-term research under DEA authorization. Historically, cannabis contained just 2 percent to 4 percent THC. Today's strains routinely exceed 15 percent and even 30 percent, with concentrates reaching 90 percent or higher. Modern, high-THC cannabis is pharmacologically distinct from traditional forms and is linked to alarming public health consequences. Research shows that 30 percent of daily users develop Cannabis Use Disorder. Studies in Lancet Psychiatry (2019) and JAMA Pediatrics (2022) associate high-THC cannabis with increased psychosis, schizophrenia risk, and cognitive impairment in adolescents. This includes IQ decline and memory deficits. To ignore these risks would be to mislead the public into believing cannabis is safer than it truly is. Worse, rescheduling to Schedule III — placing marijuana alongside drugs like ketamine and anabolic steroids — would falsely legitimize today's high-THC products as 'medicine,' despite their well-documented dangers. Beyond public health concerns, rescheduling marijuana raises questions about hidden financial motives. Moving cannabis to Schedule III would provide a massive windfall for the industry by eliminating IRS tax code Section 280E, which currently prevents marijuana businesses from deducting ordinary expenses, which costs them billions annually. Without this restriction, corporations could save hundreds of millions in taxes, expand aggressive marketing and lobbying efforts, and flood the market with even stronger THC products. Given these incentives, any push for rescheduling should be scrutinized for its potential to prioritize profits over safety. Rather than blanket rescheduling, a more responsible approach would be to maintain high-THC cannabis in Schedule I — due to its abuse potential and mental health risks — while permitting FDA and DEA exceptions for research on low-THC (below 4 percent) cannabis, the plant's natural form. If future studies confirm medical benefits for low-THC cannabis, it could then be reclassified to Schedule II with strict controls to prevent misuse. This targeted solution balances medical access with public safety, avoiding the uncontrolled proliferation of high-potency THC products. Importantly, maintaining the natural THC threshold as a research benchmark ensures that policy remains grounded in science rather than industry influence. Ultimately, an objective assessment of marijuana must rely on reliable science, consider all risks, and reject corporate-driven loopholes. High-THC cannabis undeniably meets all three criteria for Schedule I classification. It has a high potential for abuse, no accepted medical use for smoked or vaped forms, and a lack of established safety under medical supervision. Rescheduling would serve as a gift to the marijuana industry at the expense of public health, accelerating the spread of a potent and addictive drug. Instead of rushing to relax federal safeguards, policymakers should prioritize rigorous low-THC research without compromising existing protections. The Schedule I classification must remain — not due to outdated ideology, but because drug policy should be dictated by science, not corporate lobbying. Keeping marijuana in its current category is a necessary step to protect public health and ensure that any future reforms are based on evidence rather than financial incentives.

Las Vegas' growing mosquito problem is 'a ticking time bomb'

LAS VEGAS — If at one time it was thought mosquitoes couldn't survive in desert climates, this city is a case study in how wrong that is. Mosquitoes typically prefer more tropical, humid conditions, but these biting machines have exploded in number throughout the Las Vegas Valley in recent years because of a host of changes. A mix of urban development, climate change, insecticide resistance and genetic adaptations are creating a more hospitable environment for the insects in southern Nevada. Las Vegas is hardly alone in its battle against the pesky insects. Warmer temperatures and shifting weather patterns are expanding the geographic range in which mosquitoes live and breed. In many ways, what's happening here is playing out across the desert Southwest and beyond. The mosquitoes have brought with them not only the nuisance of bug bites, but also the major threat of mosquito-borne diseases such as dengue fever and West Nile virus to Las Vegas and the rest of Clark County. It's also caught people off guard. 'People aren't wrong that mosquitoes shouldn't really thrive in desert conditions, but it's clear that the particular set of species that we do have in Clark County has adapted to the local ecology,' said Louisa Messenger, an assistant professor in the department of environmental and global health at the University of Nevada, Las Vegas. 'A ticking time bomb' The species that have taken hold in Clark County include Culex mosquitoes, which can carry West Nile virus, and Aedes aegypti mosquitoes, the primary spreaders of dengue. What's more, Messenger and her colleagues at UNLV have found that mosquitoes in Las Vegas are becoming resistant to insecticides, a major public health risk in a city built on tourism. 'It is a little bit of a ticking time bomb,' Messenger said. She has for some time been concerned about how vulnerable Las Vegas is to mosquito-borne diseases. In particular, dengue has been surging in North America and South America, with more than 13 million cases recorded across the continents in 2024, according to the Centers for Disease Control and Prevention. 'In Vegas, we have more than 48 million visitors coming through our doors every year from all over the planet,' Messenger said. 'It just takes a couple of mosquito bites to start local transmission.' Last year, there were 26 reported cases of West Nile virus in humans in Las Vegas, according to the Southern Nevada Health District, trailing the city's largest outbreak of 43 cases in 2019. Yet, in 2024, scientists still found a record number of mosquitoes that tested positive for the virus in and around the city, which suggests the risk of exposure was very concerning. This year, the public health department hasn't identified any human cases so far, even as mosquitoes have tested positive for the virus in certain ZIP codes. Messenger said it's not well understood what specific factors fuel outbreaks in some years and not in others. 'We see these overlapping factors but they are quite difficult to tease it apart,' she said. 'All we can say for certain is that we have these bumper years and these zero years, and they are hard to predict.' The Southern Nevada Health District has been conducting mosquito surveillance in the region since 2004. Its meticulous records show which mosquito species are present across the Las Vegas Valley year after year and where these flying insects have tested positive for diseases. One of the most astonishing trends in the data was the explosive growth of Aedes aegypti mosquitoes, which were first identified in Las Vegas in 2017, said Vivek Raman, environmental health supervisor for the Southern Nevada Health District. The 'relentless biters' are spreading 'In 2017, this mosquito was found in just a few ZIP codes,' said Raman, who oversees the health district's mosquito surveillance program. 'A few years later, it was six ZIP codes. Then 12 ZIP codes, then maybe 20, and now it's in 48 different ZIP codes across the valley.' In addition to being able to spread dengue, these insects are a major nuisance. 'Aedes aegypti are very aggressive daytime-biting mosquitoes,' Raman said. 'They are just relentless biters.' Unlike Culex mosquitoes, which prefer breeding near larger sources of water such as untended swimming pools, culverts or detention basins, Aedes aegypti tend to breed in much shallower standing water. 'One of the reasons they are spreading so quickly is the mosquito can lay its eggs in small containers, like if rain fills a child's toy or tires or a wheelbarrow,' Raman said. 'All it takes is a couple inches of water.' Urban development in Las Vegas has also inadvertently spurred the spread of mosquitoes in the city. Golf courses, human-made lakes and other forms of artificial irrigation have all made this outpost in the Nevada desert a welcome home for mosquitoes, according to Messenger. Climate change is likely also a factor, and it's an active area of research for Messenger and other scientists. Warmer temperatures are expanding the range of geographies for mosquitoes around the world. A warmer atmosphere can also hold more moisture, which increases humidity and rain, both mosquito-friendly conditions. In Las Vegas, how the interplay between local environmental factors and changing climate trends is affecting mosquito populations is less well understood, but the implications are paramount. 'Las Vegas is kind of a case study for what climate change is going to look like in other parts of the world,' Messenger said. 'We're seeing record-breaking temperatures, we're becoming much more arid, precipitation is becoming much more aberrant and unpredictable. That's what large parts of the world are going to look like over the next 15 to 25 years.' What that means for mosquitoes in the city remains to be seen, but the problem so far shows no sign of slowing. The Southern Nevada Health District conducts public outreach on how to identify and protect against mosquito breeding sites in and around homes, and how to prevent mosquito bites. But, controlling the number of mosquitoes in the city — and thus controlling the public health risk — will require a coordinated effort from the local government, Messenger said. Currently, there isn't one in Las Vegas. 'You've got private pest companies that people can call for severe infestations, you have some work going on around wetlands, but what we don't have, which many other jurisdictions have, is a centralized, coordinated abatement,' Messenger said. That lack of coordination has resulted in mosquito populations building up resistance to insecticides, she added. A centralized effort could assess which chemicals are safe to use — particularly around humans — and monitor the performance of insecticides and pesticides to prevent mosquitoes from building up immunity. In the years ahead, Messenger said, prevention and control will be key to protecting the residents of Las Vegas and its many visitors from around the world. 'The bottom line is that this is entirely preventable,' she said. 'Nobody in southern Nevada, in Clark County, should be getting bit by mosquitoes and contracting any kind of virus.'
