How do you get as high as possible? It’s an age-old question that has consumed weed smokers, growers, researchers, scientists, and anyone who’s ever put some kind bud to their lips since humans first discovered the plant.

Recently, a study came out on the best way to roll a joint and get the highest concentration of cannabinoids. We’ve read, questioned, and tested it to see if there’s any validity to the study’s findings.

What is the best way to roll a joint?

You’d think that reaching certain degrees of high is a numbers game around buying weed with the highest percentage of THC possible — but it’s not. Scientists reported in a study by Scientific American that, with joints, how high you get is largely defined by how the joint was engineered, from how the weed was broken down and rolled to how the joint burns.

They broke the weed down by different weed particle sizes and hand-rolled the joints to test it. Then, they measured what percentage of cannabinoids reached the end user’s lips and bloodstream. The results alleged that the quality of a joint and getting the most cannabinoids and compounds per puff is about the size of the weed particles after grinding them, the roll quality, and how evenly the final product burns.

The study was headed by Markus Roggen, president and chief science officer of Delic Labs, a cannabis and psilocybin research facility in Vancouver, British Columbia. Roggen and his colleagues questioned whether cannabinoid concentration was the most important factor in determining cannabis’s intoxicating effects and what other factors contribute to an enjoyable experience.

The team of scientists crafted a study where a smoke machine puffed on three pre-rolled paper cones in the same capacity and then measured the volume of cannabis compounds that were delivered. They used a coffee grinder and sieve to grind the cannabis and then hand-rolled the joints. The samples had weed particles that were one millimeter, three millimeters, and five millimeters in diameter.

They made joints from half-gram samples of each and used a “smoke cycle simulator” that inhaled six times for three seconds before exhaling. Filters collected the aerosols at the machine’s 3D-printed mouthpiece, and the researchers used analytical chemistry techniques to measure aerosol levels from puffs taken at the beginning, middle, and end of each joint.

How did we roll the “best” joints possible?

I used this chart to determine what kind of sieve to purchase to get the particle size right. Then I hit Amazon for the cops:

Note: smoking by particle size requires way too much work, and I know you aren’t going to put that effort in. But we did, ya know, for science. However, human trial and error greatly affects variable results in this experiment.

Before testing, I knew the best time to smoke would be in the morning while I was completely sober, so I spaced the samples out between Tuesday, Wednesday, and Thursday mornings. The original study agreed that a human volunteer could not assess this many samples back-to-back with accurate results.

Step 1

I used a red Solo cup and a basic kitchen scale to weigh 0.5-gram samples of LA Cherry Runtz from Flight Path. I rubbed them against the sieves to break down the weed.

Step 2

I hand-rolled the samples into 1.4-inch OCB Virgin Cones.

Step 3

I inhaled.

During the smoke, I hit each joint six times for three “Mississippis” — the true way to count seconds, just as the study suggested. I jotted my journey over the following three hours to remember and compare the feelings.

Results

Ultimately, I know what you’re wondering: Could I really tell the difference between the highs based on particle size? Unfortunately, no, I could not. I just got high like any other time I’ve smoked a lil’ half-grammer.

When using different sieves for different particle sizes, I did not detect a higher high between a joint rolled with 1mm and 5mm particles. Perhaps some sort of monitor would have suggested differently, but if we’re going off of a human test and human feelings, it simply wasn’t there.

What does this study mean for the future of joints?

As of right now, nothing. Weed companies are not about to start marketing products based on particle size in a world where they are still fighting the THC percentage and indica vs sativa vs hybrid battles. But the information is still nice to know.

Gina Coleman/Weedmaps

Amber Wise, scientific director of the cannabis testing lab Medicine Creek Analytics, said, “Roggen’s data supports the argument that THC percentage matters less than particle size, and pre-roll manufacturers will find this useful.” According to Scientific American, the study concluded that further progress would require addressing variability that persisted in the team’s measurements — even between identically prepared joints.

In future work, Roggen and his colleagues plan to examine how other factors, including humidity, combustion source, and packing density, influence a joint’s architecture and effects. We’ll be around to test those findings, too.

Mixed Messages From The Feds About Cannabis

Published

The federal administration is all over the board around fed cannabis policy…and millions of patients are worried.

The industry employees over 440,000 workers at all lives and is driven in a large part by mom and pop businesses. Millions use medical marijuana for health issues ranging from chronic pain to sleep. But there are mixed messages from the feds about cannabis, and people are very worried. The federal government’s stance on marijuana has become increasingly complex, as recent developments show conflicting approaches to the drug’s potential benefits and risks. On one hand, there’s a push for research into medical marijuana for veterans, while on the other, a campaign against cannabis use is being launched.

The juxtaposition of initiatives highlights the federal government’s inconsistent approach to marijuana policy. While some departments are exploring the potential benefits of cannabis, others are actively working to discourage its use. This dichotomy is further exemplified by ongoing legislative efforts. For instance, Rep. Brian Mast (R-FL) has reintroduced the Veterans Equal Access Act, which would allow VA doctors to recommend medical marijuana to patients in states where it’s legal. Meanwhile, documents from an ongoing lawsuit suggest that the DEA may have weighted the marijuana rescheduling process to ensure rejection of moving the drug from Schedule 1 to Schedule 3.

The Department of Defense (DOD) has allocated nearly $10 million in funding for research into the therapeutic potential of MDMA for active-duty military members. This initiative, driven by congressional efforts, aims to explore MDMA’s effectiveness in treating conditions such as post-traumatic stress disorder (PTSD) and traumatic brain injury (TBI). Rep. Morgan Luttrell (R-TX) expressed pride in this development, stating that it could be a “game-changer” for service members battling these combat-related injuries.

Additionally, a bipartisan effort in Congress has been pushing for VA research on medical marijuana for PTSD and other conditions affecting veterans. The VA Medicinal Cannabis Research Act, introduced in both the Senate and House, would mandate studies on how cannabis affects the use of addictive medications and impacts various health outcomes for veterans.

In stark contrast to these research initiatives, the Drug Enforcement Administration (DEA) has partnered with an anti-cannabis nonprofit to launch a social media campaign targeting young people. The campaign, set to run ahead of April 20 (4/20), aims to “flood” Instagram with anti-cannabis content. The DEA is offering monetary incentives to students for creating and posting anti-THC videos, with payments ranging from $25 to $50 depending on the type of content produced.

This approach has raised eyebrows, as it seems to contradict the growing acceptance and legalization of marijuana across the United States. Critics argue that such campaigns may be out of touch with current societal trends and scientific understanding of cannabis.

How Hemp Helps You Sleep

Not everyone has access to marijuana to help them sleep – good news, hemp is available.

it’s estimated 50 to 70 million Canadian and American adults experience sleep disorders or disturbances, and about one-third of adults don’t regularly get the recommended amount. Hemp has emerged as a promising natural remedy for those seeking better sleep. With its calming properties and potential to address various sleep-related issues, hemp-derived products are gaining popularity among individuals looking to improve their rest. Here is how hemp helps you sleep.

RELATED: Mike Johnson And Marijuana

Hemp contains several compounds contributing to better sleep quality. Cannabidiol (CBD), a non-psychoactive component of hemp, has shown potential in promoting relaxation and reducing anxiety, which can often interfere with a good night’s rest. Studies suggest that CBD may help individuals fall asleep faster and experience fewer sleep disturbances throughout the night.

When formulated and used properly, preliminary research and user reports suggest that hemp gummies improve subjective sleep quality. Users of quality hemp sleep gummies report feeling more rested, a better quality of sleep and fewer awakenings in the night. However, clinical research has shown that over consumption of THC negatively impacts the quality of sleep, especially with long term use.

Wana Brands has launched a hemp sleeping product nationally, Mike Hennesy, Vice President of Innovation shared the following about how it works. Naturally hemp-derived sleep gummies contain the same cannabinoids like CBD, CBN, and THC as cannabis or marijuana. These ingredients interact with receptors in the body’s endocannabinoid system, which plays a role in regulating mood, stress, and sleep-wake cycles. For example, CBD may promote relaxation and reduce anxiety, CBN can relieve discomfort and reduce awakenings, while THC can shorten the time it takes to fall asleep, especially at low doses. Together, they may help ease the mind and body into a sleep-ready state.

The best sleep products don’t rely on just one cannabinoid like CBN but instead use a combination of cannabinoids, terpenes, and other sleep-supporting ingredients such as melatonin. This is because the reasons for sleeplessness are multifaceted, and include trouble falling asleep, staying asleep, chronic, pain and anxiety. Each ingredient targets different root causes as well as synergizes with the other cannabinoids and terpenes for the best night sleep.

Longer lasting formulations can actually help reduce awakenings in the night. CBN has been shown in recent research to reduce the number of times you wake up in the night. Combined with other cannabinoids they can synergize to reduce discomfort and anxiety helping consumers stay asleep.

If you do wake up in the middle of the night and can’t fall back asleep products including CBD and CBG to reduce middle of the night anxiety and racing thoughts that can keep us awake, and they have only 1mg of THC so you wake up refreshed and not high in the morning.

For most people, hemp-derived cannabinoids are considered safe and non-intoxicating, with a low risk of dependence. When THC is included in small amounts, it can produce mild effects and can help us fall asleep faster. It generally poses a minimal risk when used in moderation, but there is a potential for dependence if overused, just like with any sleep aid. Adverse events are far more prevalent in pharmaceutical and even over the counter sleep aids than with hemp-derived cannabinoids.

The key is responsible use, including starting with a low dose and taking breaks when needed. If you rely on it every night at high doses, your body may adjust, and it can be habitual. But when used in moderation and with a well-balanced formula, cannabis can be a sustainable part of a healthy sleep routine.

This Wine Issue Is Becoming More Common

Wine is one of the popular drinks in the world,

Roughly 75% of adults worldwide drink wine, with a significant portion consuming it regularly, and the US wine market sees a substantial number of people drinking wine and refining their taste. In fact, mearly half of adults (44%) drink at least a couple of glasses per week. But this wine issue is becoming more common, Charles Rice, Executive Director of the Wine Education Council shares the following.

Imagine attending a wine tasting, only to discover an unpleasant surprise with one of the bottle. It is bitter and even a little medicinal; it is starting and upsets the balance of the really brings down the whole room and spoils what could have been a lovely evening. This uninvited guest is called ‘smoke taint’ and it a direct result of the increase in wildfires affecting many of the world’s top wine-growing regions. Let’s pour ourselves a glass and explore how this unwanted visitor is crashing the party and what the industry is doing to air out the room.

Smoke taint is like a bad hangover for grapes—it leaves them feeling a bit burned. When wildfires rage nearby, mature and growing grapes absorb volatile compounds, imparting an ashy, smoky flavor to the wine. It’s not just a surface issue: these compounds penetrate deep, forming glycosides that release their smokiness during fermentation. The result? Wines that taste more like a campfire or a doctor’s office than a sophisticated vintage. It’s a “grape” big disappointment!

Rising temperatures and changing weather patterns are fueling longer and more intense fire seasons. This means more frequent and severe wildfires, especially in regions like California, Oregon, and Australia—some of the world’s top wine-producing areas. The impact is twofold: not only do fires directly damage vineyards, but the smoke also compromises grape quality, leaving winemakers feeling crushed. It’s a drain on their passion, and their profits.

Fortunately, researchers are working tirelessly to find ways to put a cork in the problem and coming up with some innovative solutions. Synthetic materials called ‘molecularly imprinted polymers’ can selectively remove smoky compounds from wine without stripping away desirable flavors and aromas. Activated carbon has been shown to be effective but can also remove some of the good stuff. It’s akin to using a broad-spectrum filter that catches both the smoke and some of the wine’s natural charm. Interestingly, producing sparkling wine from smoke-affected grapes is another creative workaround. The carbonation process can mask some of the smoky flavors, turning a potential loss into a bubbly opportunity.

Smoke taint is undoubtedly uninvited guest when it comes to wine in the age of climate change, but the wine industry is not going to complain too much about sour grapes. With innovative solutions and a dash of creativity, winemakers are finding ways to keep the party going. So, the next time you sip a glass of wine, remember the uninvited guest that might have been there, but thanks to science and ingenuity, didn’t ruin the party.
