The Fragrance of Marijuana Before and After Consumption
Marijuana is the dried leaves and flowers of the cannabis plant. Cannabis has psychoactive and medicinal properties because of its chemical makeup.
Marijuana can be rolled up in a handmade cigarette (a joint), in a cigar, or in a pipe (a bong). It can be used for pain relief, to treat anxiety, or for recreation.
In many states, the sale and use of marijuana without a prescription is still illegal.
You can usually tell if someone has been smoking marijuana by detecting the scent of piney, slightly skunky grass that smoked cannabis leaves behind.
But figuring out for sure if what you’re smelling is weed can be a little difficult if you aren’t attuned to the scent. Various strains of marijuana can smell different from each other, making it even more complicated.
This article will cover what marijuana smells like in different stages of its use and consumption, as well as some differences between strains.
The strongest factor in the way marijuana smells is the age of the cannabis plant when it’s harvested. Cannabis that’s harvested earlier in its life cycles has a milder, less skunky scent.
It’s also less powerful when you smoke it. Cannabis that grows older before it’s picked and dried will have a stronger odor.
Organic compounds called terpenes are found in all plants, including cannabis. Myrcene (mango), pinene (pine), and limonene (lemon) are terpenes found in some strains of cannabis.
Terpenes change the scent of marijuana. For example, cannabis strains with pinene will smell more like pine.
Marijuana plants smell similar during the growing process and when they’re harvested and dried. They give off a slightly weedy, piney “skunk” scent that gets stronger as the plant grows older.
When cannabis flowers and blooms, the scent becomes powerful.
Indica vs. sativa
For decades, botanists and marijuana connoisseurs claimed that indica and sativa are different species with distinctly different effects on the body. Indica strain smells more acrid, while sativa smells more spicy or sweet.
But it would appear, at least to some experts, that there’s no way to smell the difference between indica and sativa definitively. Part of the reason is that there’s a lot of crossbreeding between these two particular strains.
However, one small study did find that participants who had purchased weed within the prior several months were able to smell the difference between several different strains of marijuana.
Marijuana consumers describe the scent of the plant as earthy, herbal, and woody. Sometimes the plant scent carries notes of lemon, apple, diesel, or plum.
Dried marijuana smells a lot stronger than some other dried plants.
When you’re smoking marijuana, the natural scent of the cannabis scent is amplified by the smoke it creates. Fire, smoke itself, ash, and the smell of rolling paper add additional layers to the scent.
When a person is smoking cannabis, notes of lemongrass, pine, fire, and wood may stand out. The distinct “skunk” smell of marijuana is often reported.

It looks like weed, smells like weed, but is it weed? Some states crack down on smokable hemp
Hemp plants can be made into anything from rope and insulation to granola. But today, most U.S. hemp farmers are growing hemp to produce cannabinoids, such as CBD — which means they’re growing plants that look like marijuana, smell like marijuana, and, increasingly, are rolled into joints and smoked like marijuana.
People smoke marijuana to feel high, but they smoke hemp — a non-psychoactive form of cannabis — to ingest cannabinoids users say ease aches, pains, and stress.

Now, some state lawmakers, alarmed by how difficult it is for law enforcement officers to tell the difference between hemp buds or joints and illegal pot products, are cracking down on smokable hemp.
Louisiana and Indiana banned smokable hemp sales in 2019, and Texas banned smokable hemp manufacturing. Kentucky banned sales of hemp cigarettes, cigars, whole hemp buds, and ground flowers in 2018. And a battle over whether to allow sales of dried hemp flower, pre-rolled hemp joints, hemp cigarettes, and other smokable products has stalled a North Carolina bill that would regulate hemp production and sales in the state.
“My philosophy right now is, we are actually legalizing recreational marijuana if we don’t listen to our law enforcement and do something about this,” said North Carolina state Rep. Pat McElraft, a Republican and deputy House majority whip.

The rise of hemp products so similar to marijuana has caught some lawmakers by surprise. Nobody talked about smoking hemp or said police couldn’t tell the difference between hemp and marijuana when North Carolina created a hemp pilot program in 2015, McElraft said.
Farmers and hemp businesses are fighting the bans, arguing that they violate federal law and hurt a nascent industry. The 2018 farm bill legalized hemp sales and defined hemp as any part of Cannabis sativa L. with a tetrahydrocannabinol, or THC, concentration of 0.3% or lower.
There are no bans on smokable hemp in Pennsylvania and New Jersey. Both states issued regulations last week for growing the plant. Pennsylvania farmers grew 4,000 acres of the crop in 2019. No hemp was legally cultivated last year in New Jersey.
“If the North Carolina legislature wants to waste its time attempting to ban a smokable hemp — OK,” said Bob Crumley, founder and CEO of North Carolina-based hemp company Founder’s Hemp and a lawyer who has advised policymakers on hemp issues. “It’s not going to survive a court challenge.”
Besides, the market for smokable flower — the most pristine, cannabinoid-rich plants — is the most lucrative many hemp farmers, retailers, and distributors can access.
That includes Indiana businesses, said Justin Swanson, president of the Midwest Hemp Council, an Indianapolis-based industry group that supports smokable hemp.
“The bill Indiana ended up passing was like essentially telling a cattle farmer, ‘Hey, you can sell beef, but you can’t sell steak,’ ” he said.
Hemp or marijuana?
Nationally, people spend more money on hemp CBD oil than on smokable flower. The biggest CBD product category — tinctures — hit about $1 billion in sales in 2019, said Virginia Lee, CBD research manager at the Brightfield Group, a cannabis market research firm based in Chicago.
By contrast, an estimated $70.6 million of hemp CBD pre-roll (a.k.a. joints) and raw flower were sold in the United States in 2019, Lee said. But, she said, those sales are growing.
People buying smokable products aren’t the stoner set associated with weed, Crumley said. “This product, smokable hemp, in my stores is being used by everyone from soccer moms, who want to have anxiety or stress release but not get high, to cancer patients,” he said.
Some consumers prefer to smoke hemp flower rather than ingest hemp oil because smoking delivers cannabinoids straight to the bloodstream, Swanson of the Midwest Hemp Council said. Others smoke because they don’t have to worry about toxic additives or mislabeling with dried buds.
“I’ve had a lot of people tell me they’re a lot more comfortable using this way,” he said.
For hemp farmers, plants high-quality enough to sell with minimal processing can be a big moneymaker. CBD smokable flower last month was selling for between $150 and $350 a pound, said Ian Laird, CFO and general counsel of New Leaf Data Services, a Connecticut-based market research firm that tracks cannabis prices. That’s more than hemp biomass for making CBD oil.
“You’re talking about a huge, huge opportunity for farmers,” Swanson said.
Yet smokable products make some policymakers wary. Concerns about the health dangers of smoking and vaping CBD, along with fears that hemp could, in fact, be psychoactive, play a role in lawmakers’ decisions to ban smokable products, said Jonathan Miller, general counsel for the U.S. Hemp Roundtable, a Lexington, Ky.-based industry group.
“There’s some concern that hemp pre-rolls are Woodstock-era marijuana — what marijuana used to be 30, 40 years ago,” he said. A level of about 1% THC is considered the threshold for cannabis to have a psychotropic effect, according to the nonpartisan Congressional Research Service.
But pushback against the sale of smokable hemp products from police departments, state law enforcement agencies, and district attorneys has dominated the debate in states such as North Carolina.
“It’s a flowering product that looks like marijuana, smells like marijuana, and unless you go to a specific lab for testing, you can’t tell the difference,” said Peg Dorer, director of the North Carolina Conference of District Attorneys.
The North Carolina state crime lab doesn’t have testing equipment sensitive enough to gauge the amount of THC in a cannabis sample, Dorer said. “In order to test it, they would need to send it to a private lab, and that is expensive, and we don’t have the budget for that kind of thing.”
Law enforcement officers in the state worry that the proliferation of smokable hemp will make it impossible for them to search a person or property for marijuana based on the smell of weed, said Roxboro Police Department chief David Hess, first vice president of the North Carolina Association of Chiefs of Police.
The current version of the North Carolina Farm Act, to be taken up by lawmakers again this year, defines smokable hemp as “harvested raw or dried hemp plant material, including hemp buds or hemp flowers, hemp cigars, and hemp cigarettes” and classifies it as a form of marijuana.
The legislation does allow licensed hemp producers to grow and process smokable hemp, as long as they don’t sell it within state borders. “You could still sell it outside of North Carolina,” Dorer said. “That was our compromise.”
Republican state Sen. Brent Jackson, a farmer, said in an email to Stateline that he remains hopeful lawmakers will sign off on his bill that would allow smokable hemp sales. “The federal Farm Bill of 2018 made it very clear that all hemp shall be legal,” he said, “and it is my intention to support the hemp growers, processors, and retailers as they move this new industry forward.”
Farmers fight back
Hemp industry groups, meanwhile, are fighting the smokable hemp bans.
“We don’t want to start our state program with a ban in place on any part of the plant that’s compliant,” said Blake Butler, executive director of the North Carolina Industrial Hemp Association. “Even though it’s being smoked, it’s still an agricultural commodity.”
Butler’s looking to Indiana, where last fall the Midwest Hemp Council and seven hemp businesses won a preliminary injunction against a 2019 Indiana law that defined “smokable hemp” as hemp products that allow THC “to be introduced into the human body by inhalation of smoke” and made manufacturing, delivering, or selling smokable products a misdemeanor.
In their suit against the state, the hemp businesses argued that the law’s smokable hemp provisions violate the 2018 farm bill and would seriously harm them and their businesses. The state attorney general’s office argued that Indiana’s law complies with the farm bill and protects the public.
“Permitting smokable hemp to be produced or possessed in Indiana would present significant obstacles to the ability of law enforcement to enforce Indiana’s laws against marijuana,” it argued.
U.S. District Senior Judge Sarah Evans Barker of the Southern District of Indiana sided with the hemp industry. “The fact that local law enforcement may need to adjust tactics and training in response to changes in federal law is not a sufficient basis for enacting unconstitutional legislation,” she ruled in September.
The Indiana Attorney General’s office is appealing the decision.
Although the court fight is far from over, the Barker ruling should give lawmakers pause, said Rod Kight, a cannabis attorney based in Asheville, N.C. “I think it’s a very strong signal to state legislatures that they can’t get in the way of hemp that’s now federally legal,” he said. “They can’t stop a whole piece of the hemp industry from going into effect and thriving.”
If North Carolina Gov. Roy Cooper, a Democrat, does sign a law banning smokable hemp sales, Butler said his group will take legal action.
But he’s hopeful that hemp businesses and law enforcement groups can team up to solve the problem of policing smokable products. “We respect law enforcement,” Butler said, “and we need to work together.”
A proposed bill in Tennessee could be one way to neutralize police opposition, he said. It would extend the 6.6% excise tax on smokeless tobacco products to hemp products people either smoke or consume like snuff and chewing tobacco.
Money raised by the tax could help law enforcement groups buy roadside THC testing equipment and fund other hemp industry priorities such as research and development, said Joe Kirkpatrick, president and chief lobbyist of the Tennessee Growers Coalition, a hemp advocacy group based in Nashville.
A 2019 Tennessee law prohibits the sale of smokable hemp products to minors. Kirkpatrick said lawmakers’ approach to regulating such products has been influenced by their desire to help farmers, particularly tobacco farmers grappling with falling sales.
“Farmers really need an alternative specialty crop,” Kirkpatrick said. Smokable hemp, he said, isn’t known to be carcinogenic or addictive and might just be the next tobacco. “It would be much better than the vape poisons that [tobacco companies are] pushing on the youth,” he said of hemp.
Hemp looks and smells like psychoactive marijuana. Law enforcement has a hard time telling the two apart.
