What is top-shelf weed?

First, let’s cover our bases and go over the common terms used when shopping for good weed. “Flower” refers to the dried and cured female cannabis plant’s blooms, often called “nugs” or “buds.” Flower is typically intoxicating — THC content is the primary indicator of euphoric potency — but some flower has high CBD content and will produce less intoxicating effects.

The best smoking experiences, edibles, tinctures — even CBD oil — often come from the best source material, or “top-shelf bud.” In terms of slang, premium weed is also commonly referred to as the “loud,” “fire,” “dank,” and “Private Reserve.” Low-grade weed is often referred to as “schwag,” “brick,” “ditch,” and “bunk” weed.

Identifying high-quality flower can throw even the most experienced cannabis connoisseurs for a loop, but the key traits that separate good weed from bad weed are smell, appearance, feel, and flower structure. In this article, we’ll break down all four and offer tips for spotting the good stuff and avoiding the bad.

What to look for in good weed

1. Smell: Cannabis cultivated and cured to the highest standards typically exhibits a pungent and pleasant aroma. Flowers emitting a strong fragrance are commonly referred to as having a “dank” or “loud” odor, indicating the overall quality of the flower. There are a variety of terms for the types of aromas high-quality cannabis emits, including skunk, diesel, and pine. The common denominator is that a good-smelling flower is distinct, pungent, and unmistakable. The stronger the fragrance is, the more nuanced the experience is likely to be.

2. Look: High-end flower, like fresh, healthy produce, provides a few visual hints to help you determine its quality. While all good cannabis should be visually appealing, a top-shelf strain can easily display a vibrant array of colors. Good-quality flowers are often a deep green with flaming orange or red hairs. They can also express colors from deep purple to bright blue.

Another important visual indicator of good weed is the amount and viability of trichomes. Trichomes are the tiny, glimmering crystal-like appendages on the plant’s surface that create and hold the compounds responsible for the flower’s smell, flavor, and effects. The more frosty trichomes you can see with the naked eye, the better indicator of the flower’s intoxicating and therapeutic potency. If your eyesight has seen better days or you want to get up close, use a magnifying glass to get an even better sense of a nug’s trichomes.

3. Feel: Top-shelf flower should be sticky and slightly spongy when you touch or gently squeeze it between your fingers. Stems should snap and the bud should be relatively easy to break apart, but shouldn’t be completely dry or crumble when you touch it. Alternatively, buds shouldn’t be too wet or soft, since these have a higher chance of developing or containing mold or mildew.

4. Flower structure: Skillfully cultivated and cured sativa-leaning flowers tend to be light and fluffy in shape and composition, while indicas tend to be tighter and denser in flower structure. Though the structure and the experience you end up having usually have little to do with each other. Rock-hard flowers are a sign that cultivators may have used plant growth regulators, which can lead to an unpleasant taste. Extremely fluffy flowers could be a signal that the plant was not grown under sufficient light intensity and was not cultivated to its potential.

While top-shelf flower is the hallmark of a great dispensary, good flower comes in many shapes and sizes and has more than a few nicknames.

Other qualities to look for in good weed

There are a few other quality benchmarks to consider when tracking down the best weed. Dr. Adie Rae, a neuroscientist at the Legacy Research Institute in Portland, Oregon, and scientific adviser to Weedmaps, pinpointed three more key indicators of weed quality: ethical cultivation, ethical companies, and diverse chemistry.

1. Ethical cultivation: Rae emphasized that ethical cultivation avoids synthetic fertilizers, uses living soil, and practices sustainable agriculture. “Look for Clean Green Certified, Sun+Earth, or other organic products and producers who use regenerative agricultural practices. Sungrown cannabis often ticks all of these boxes,” Rae advised.

2. Ethical companies: Small, craft producers and family-owned businesses are often the most ethical, according to Rae. “Look for women-, Black-, and minority-owned producers… large corporations are paying more attention to yield and profits than plants,” she stated.

3. Diverse cannabinoids: A diverse cannabinoid and terpene profile is desirable in CBD products. Rae recommended that consumers ask to see the Certificate of Analysis before making a purchase. The certificate provides a comprehensive list of cannabinoids contained in the product in addition to therapeutic terpenes and any potential contaminants such as pesticides or heavy metals.

How do I know if it’s bad weed?

1. Smell: Low-quality flower can take on a variety of quirky fragrances, which typically means a batch of bad weed. Often referred to as “schwag” or “bottom shelf,” these low-end buds can reek of a musty or mildewy aroma. A musty or straw-like aroma is a clear indication of aged or compromised cannabis. Typically, when stored away from light and heat, cannabis has around a one-year shelf life before starting to really degrade. Unpleasant aromas are generally a sign of mishandling, poorly cured cannabis, or advanced age.

2. Look: The appearance of low-quality flower is distinct. It can come in the form of discolored flower or an abundance of stems and seeds. There are many reasons flower can become discolored ranging from mold and age to pesticides and chemicals. The bottom line is that you don’t want to buy it, let alone smoke it. One very important indicator of bad weed is the appearance of amber-colored trichomes. With time, light, and heat, trichomes turn from clear to an amber hue. This is a dead giveaway that you’ve been swindled into last year’s harvest.

A sad sight, low-quality cannabis is seen in many shades of degradation. From dirt brown to an immature lime green flower, nature provides several visual clues when you’re looking at a good plant gone bad.

3. Feel: When flower is of a lower quality, it will often be dry or brittle to the touch. Dry bud will feel light and airy with no weight behind it, unlike dense, sticky flower. Additionally, bad weed will easily crumble when handled, or might even be falling apart. Loose, undone flower is called “shake” and should be avoided.

Overly “wet” buds have stems that don’t snap and tend to stay put when squeezed. The extra moisture content makes for the perfect breeding ground for mold and mildew. Wet nugs that tear apart rather than break apart are a sign that a cultivator didn’t properly dry and cure their cannabis.

4. Flower structure: Poor flower structure can be easily detected with a discerning eye. While a properly cultivated flower will often be aesthetically pleasing, a carelessly grown plant can produce inferior-looking flowers. Though a plant’s structure really says nothing about its chemical composition, it can still tell a story. Improper lighting or growing conditions can lead to “fluffy” or “airy” nugs, and while they may contain high levels of cannabinoids and terpenes, their density is still widely and harshly dismissed by the cannabis community.

Other indicators of bad weed

You may think you’re getting better quality bud with a sky-high THC concentration, but Dr. Rae dispels this myth. She cited THC levels above 20% as a red flag and told Weedmaps, “Lab tests are not as accurate as they may seem, and there are financial incentives for labs to produce increasingly higher THC values. Especially with flowers labeled around 30%, be very wary of fraudulent lab results.”

Rae also pointed out that there is not necessarily a relationship between enjoyment and THC potency. Distinguishing between enjoyment and intoxication, Rae asserted, “You can still have a very nice experience with 5-10% THC.”

Is expensive weed always good?

And is cheap weed always bad? Rae suggested that a low price point could indicate an older product past its shelf life but said that sometimes, “You can often get a nice-smelling, fresh flower for a good value. Beware if a pricey flower has a high THC level, but often a high price reflects the extra care and attention required to make a truly craft product.”

Check the harvest date and test the aroma before buying weed that appears unreasonably cheap. Marijuana that doesn’t pass the smell test just might be dirt weed. The bottom line, however, is that finding good weed depends on your personal taste.

Bottom line

The search for high-quality flower doesn’t have to be complicated. With a discerning eye (and nose), even novice cannabis smokers will be able to easily separate the high-quality buds from the bad.

But at the end of the day, it’s all about what you like when you smoke weed. What you prefer might be different from what the local budtender, delivery driver, or your friend likes. There are hundreds of strains grown by thousands of cultivators. The goal is to find the right strain for you. It’s simply about finding the right product that works with your personal chemistry by a brand or cultivator that you like and can thus enjoy over and over again.

So get out there, look for the four main indicators to understand what you’re getting — smell, look, feel, and flower structure. Then you’ll find a quality weed strain that best suits your personal taste.

Leafly’s Visual Quality Guide to Selecting Cannabis

You’ve learned the visual difference between cannabis quantities and how to properly store your cannabis, but can you tell the visual difference between poor and high-quality cannabis? At Leafly we constantly receive questions from our community about how to tell the quality of buds based on photos or their appearance alone. While there isn’t an exact science for selecting cannabis (most of it comes down to personal opinion), there are a number of visual cues you can look for when scanning the selection of buds at your favorite dispensary.

Picking out cannabis is a lot like selecting fresh produce or flowers — you’re looking for something that looks appealing, has a good color, and produces an enticing aroma. Additionally, you want to avoid any glaring defects like mold and mildew, insects, and discoloration. Different qualities can come from the same plant; for example, I’ve seen many dispensaries that separate the prized colas from the small wispy buds found on low- hanging branches (I call these “popcorn nugs”).

Keep in mind a few key points when assessing the visual quality of your cannabis:

  • Quality standards vary based on your location and access to cannabis, your personal experiences with the plant, and local cannabis laws.
  • There are many other attributes to consider when choosing the best strain for you, including the price, the smell, desired effects, and quantity available.
  • A high concentration of trichomes indicates a strain with advanced cannabinoid production, which leads to potent cannabis. However, potent cannabis is not necessarily indicative of high quality — it could be lacking the flavor profile you are looking for, or, for example, it may be a stimulating sativa when you prefer a mellow indica.
  • Test data can go a long way in visualizing and understanding the various attributes of each strain, so always look for current and accurate test results from a trusted third-party laboratory.

Let’s check out some examples of low, medium and high-quality cannabis so you can better assess the quality of the buds you’re acquiring.

Examples of Low-Quality Cannabis Buds

Also called: Shwag, shake weed, bottom shelf, popcorn, dirt weed, brick weed, ditch weed, Bobby Brown, and more

Low-quality cannabis is often transported as compact bricks, resulting in a mix of shake, stems, and compressed buds. Typically only found on the black market, shwag tends to be less colorful than your average cannabis, often more brown than green (thus the nickname Bobby Brown — no relation to the former member of New Edition). It is dry and earthy in aroma with a taste that can be harsh and spicy, as opposed to the sweet and floral notes of top-grade cannabis.

When it’s not compacted into brick weed, low-quality buds tend to be light, leafy, and wispy. The concentration of cannabinoids is likely to be very low due to extreme environmental factors, like excessive heat or other variables, which cause trichomes and other crucial parts of the plant to under-develop. The harsh growing conditions typical for low-quality, improperly cared-for cannabis has a tendency to be high in CBN, a byproduct of degradation. Advanced levels of CBN are often attributed to poor or improper storage and handling during transportation.

The effects from low-quality cannabis tend to be mellow, relaxing, lazy, and sleep-inducing (thanks to the CBN). It’s not uncommon to experience headaches and other adverse side effects from poorly grown and cared-for cannabis. The lack of quality standards at the street level also opens consumers up to contaminated flower that has been tainted by dirt, mold, mildew, insects, and even pesticides.

One glaring advantage of low-quality cannabis is that it is usually available at discounted prices. While I wouldn’t normally recommend consuming sub-standard buds, some cannabis consumers prefer to bargain hunt and turn their shwag into affordable and effective edibles.

Examples of Medium-Quality Cannabis Buds

Also called: Mids, middle shelf, regs, Reggie, beasters, B+, work, and more

Medium-quality cannabis is where most domestically-grown US cannabis lands on the quality scale. Northern states also see an influx of mids and regs from commercial Canadian cannabis, known as Beasters or BC Buds (though the influx is starting to dwindle now that the US is shifting towards legal access).

Mids can be identified by their spectrum of green hues and the presence of colorful pistils. Solid middle shelf genetics showcase purple tinge, moderate flavor profiles, and sugary trichomes. Seeds and stems are minimal-to-none, but the buds can suffer from a number of quick-to-market techniques like improper flushing of nutrients, quick curing methods, and sloppy trim jobs. Pricing for middle quality is somewhat standardized based on your region, and oftentimes bulk discounts become available when buying more than a ¼ or ½ oz at a time.

Experiences with Reggies can vary across the board, but generally if the genetics are strong, the resulting effects are potent and enjoyable. Unstable genetics or stressful environments can cause hermaphrodite plants that begin to show both sexes. These partially-formed seeds are often referred to as bananas for their elongated shape and yellow hues.

Examples of High-Quality Cannabis Buds

Also called: Fire, primo, top shelf, loud, kill, chronic, dank, headies, flame, kine, kind, and a host of other regional naming trends

Everybody claims to have high-quality cannabis in stock, but how can you tell for yourself?

The first thing you should know is that top-shelf buds will stand out in a sea of green. Besides the diverse spectrum of colors that premier genetics show, the amazing quality and complex aromas of truly dank weed will scream “pick me!” The nickname “loud” is used for this exact reason, because the pungent flavors are often too much to contain and can draw attention to those who have it, especially when trying to be discreet. Truly outstanding cannabis has no price cap — it can be considered a luxury item like fine wine and, depending on the laws where you live, prices can reach extreme levels.

First-class cannabis will have a thick coat of sugary resin that contains the cannabinoids and terpenes, giving the plant its powerful effects and captivating flavors. Advanced potency and flavor profiles provide a diverse range of effects and individual experiences that amplify the consumer’s connection to the cannabis plant. The buds themselves are typically dense and chunky, thick from advanced CO2 levels during the flowering cycle and other innovative growing techniques.

The harvesting, drying, and curing methods used by the grower can greatly influence the end result. Truly dank herb should be sticky from the frosting of trichomes without being moist or wet. When ground, it should break apart without becoming a pile of dust, and when burnt, it should leave behind white ash (black ash is a signal that there is excess moisture in your flowers).

Proper trimming is paramount to true connoisseurs, allowing each cola and nug to be showcased and perfectly framed. If top-shelf cannabis appears leafy, it’s most often because the sugar leaves surrounding the buds are covered with trichomes too precious to discard. Seeds are extremely rare to find in the finest-quality cannabis, so if you uncover one in your stash, keep it for your own garden (providing you can legally grow in your state, of course).

Leafly's guide to visually assessing cannabis quality identifies traits and visual cues to help you recognize the difference between high, middle, and low-quality marijuana.
