“‘Safe’ is a funny word,” both because what is harmful to one person may not be for another, and because people vary in their risk tolerance, said Jeff Raber, CEO of marijuana consulting company The Werc Shop and an instructor in the University of Denver’s cannabis program.

The same amount of a chemical in a batch of cannabis could be benign or harmful, depending on the size of the person using it, how often they smoke and how much they take at one time, among other factors, he said.

Colorado requires growers to test their harvest for yeast, mold, aspergillus (a type of fungus), E. coli and some other bacteria, pesticides and heavy metals, such as lead. Manufacturers also have to test for residual solvents and chemicals used to create their products.

Regulators had to work with limited existing information on the possible risks of pesticides and contaminants in marijuana, because few, if any, studies have examined what levels might be safe in a smokeable or vapeable product, Raber said. Rules for tobacco aren’t a particularly helpful starting place, since growers use different pesticides, he said.

“With edibles, we at least can fall back on food safety standards,” he said.

A 2013 study that Raber co-authored found that significant amounts of pesticides could pass through water pipes or glass pipes to the user. Filtration reduced the amount the user could have inhaled, though some residues still made it through. The study predates states’ current pesticide limits, though, so the risk to people using regulated cannabis now could be lower, Raber said.

Colorado based its updated 2023 pesticide regulations on rules in place in Canada, after a group of researchers and stakeholders considered various sets of standards used in other places with legal marijuana.

Colorado’s Marijuana Enforcement Division referred questions about the standards used for different contaminants to the Colorado Department of Public Health and Environment, which said it couldn’t comment.

Ideally, more studies would settle what chemicals are risky in smokeable marijuana and whether any cannabinoids offset some of that risk, but most research is still trying to sort out how the plant itself affects people who use it, Raber said. And, of course, federal law limits researchers’ ability to grow and study cannabis, though Colorado scientists have ongoing projects looking at pesticide residues and heavy metal contamination.

The lack of direct data matters because not everything present on the bud makes it into the user’s body, said Mark Lefsrud, an associate professor who studies medical cannabis at McGill University in Canada.

For example, contamination with heavy metals would cause a problem in a concentrated or edible product, but lead and cadmium don’t turn into particles that users can easily inhale when smoking, he said.

“As a recreational consumer, I’d say it’s very low odds” that heavy metals in a smoked product would be dangerous, Lefsrud said.

The same goes for E. coli, which doesn’t fair well when set on fire, Lefsrud said. E. coli outbreaks periodically sicken and occasionally kill consumers — most recently, when contaminated onions showed up in McDonald’s Quarter Pounder hamburgers — but the state of Colorado hasn’t had any marijuana recalls attributed to bacteria since at least 2020. (Two of 61 recalls in those years mentioned unspecified microbial contamination, which could refer to bacteria or fungi.)

The biggest risk for an average marijuana consumer is from fungi, Lefsrud said. People with lung diseases or compromised immune systems can become seriously ill or die from inhaling mold spores, but even generally healthy people are at risk from toxins that aspergillus and other types of mold generate, he said.

Colorado allows growers to kill excess fungus on their product, but that process doesn’t destroy any toxins that the mold has already produced. Just because a bud looks and smells normal doesn’t mean it couldn’t contain toxins, Lefsrud said.

“In most cases, it’s the things you don’t see” that are dangerous, he said.

The state does require testing if a batch fails mold testing and the grower wants to remediate it for use in products such as concentrates, according to the Marijuana Enforcement Division. The division hasn’t issued any recalls or taken any actions against marijuana businesses over products that failed toxin testing.

States differ in what kind of contaminants they regulate and the limits they set, but overall, they erred on the side of caution, Raber said. Ultimately, they had to make judgment calls based on imperfect evidence, like American and European food regulators who came to different conclusions about whether certain dyes are OK to eat, he said.

“It’s an evolving picture, but it’s evolving to get better,” he said.

States are relatively well-positioned to catch if a batch makes consumers sick in the short term, Raber said. Effects from long-term use will be tough or impossible to sort out, though, because most people use multiple products, and other differences between groups of people make it hard to pin down how much to attribute to cannabis, let alone to pesticides used on it, he said.

Raber works in the cannabis industry and isn’t interested in telling adults not to smoke, but said people should understand the uncertainties around safety.

Consumers can somewhat reduce their risk by switching up the products they use — so they don’t consistently expose themselves to a contaminant that happens to be high on one type of marijuana — and by not overdoing their use, he said.

“I think that’s the best you can do today,” he said.

The cannabis industry continues to evolve quickly, especially in the United States. In 2025, the U.S. market is expected to generate over $45 billion in revenue. This growth is fueled by expanding legalization and rising demand for both medical and recreational products. Recently, there has been momentum toward federal reform. The possibility of reclassifying cannabis to a lower drug schedule has gained support. States like New York and Maryland are also opening more dispensaries. As more legal markets emerge, Canadian cannabis companies are positioning themselves for long-term U.S. expansion. This week, several Canadian stocks are gaining attention from investors.

While the upside is exciting, cannabis stocks remain volatile. Therefore, it’s important to use technical analysis when identifying entry points. Traders often rely on volume trends and support levels to guide decisions. Additionally, proper risk management is essential. Investors should consider stop-loss orders and portfolio diversification. As the market changes, informed decisions and disciplined strategies will be key to long-term success

As the cannabis industry continues to evolve, investors are watching key players in both Canada and the United States. In April 2025, three Canadian cannabis stocks stand out. Tilray Brands Inc. (TLRY), Canopy Growth Corporation (CGC), and Village Farms International Inc. (VFF) are all worth watching. Each company has unique strengths and a growing presence in the U.S. market. Below is a breakdown of each company, along with their latest financial performance.

Canopy also saw improvement in international cannabis markets. Despite growth in some areas, gross margin declined by 4%. This was due to increased product launch costs and indirect expenses.

The post Green Thumb Industries Inc. (GTBIF) to Hold First Quarter 2025 Earnings Conference Call on May 7, 2025 appeared first on Marijuana Stocks | Cannabis Investments and News. Roots of a Budding Industry..

State Assemblyman Matt Haney, D-San Francisco, plans next week to introduce AB 564, or the Cannabis Tax Relief bill, to stop a tax hike — from 15% to 19% — set to go into effect on July 1.

Haney also authored AB 1775, which this year allowed dispensaries to open Amsterdam-style cannabis cafes with food and non-alcoholic drinks. While that bill and the one Haney is introducing next week could help boost local dispensaries’ revenues, some shops are nevertheless worried a tax hike will drive more cannabis consumers to the black market.

“The illicit or unregulated market is the biggest competition,” said Zoe Schreiber, director of compliance and public affairs for The Highlands Dispensary, which opened in unincorporated Livermore in 2022. “As a full retail community, our biggest competitors are not each other, but rather a market that’s unregulated.”

Schreiber said customers often complain of the high taxes on cannabis products at her dispensary, which can make up about 30% to 40% of the overall price out the door, she said. She said that in addition to the expected 4% excise tax increase, licensing and regulatory fees continue to drive the prices of legal cannabis products up, while pushing consumers away from the regulated market.

“‘I know a guy,’ or ‘my guy can get it to me for less.’ Those comments are ones that we do hear,” Schreiber said. “By continuing to do things to make regulated cannabis more expensive, or even where it’s at now, we lose over half the market. We lose the ability to create that safe space, which is what consumers voted for in 2016 with Prop. 64.”

Haney said he is putting the Cannabis Tax Relief forward to protect legal cannabis businesses from closing as the illegal market continues to grow at a faster rate.

“California’s cannabis industry is struggling. And a huge tax increase right now could be the nail in the coffin,” Haney said in an interview Wednesday. “This is absolutely the wrong time for a 25% tax increase on a fledgling legal cannabis industry that is trying to follow all of the rules and pay their taxes and is losing out everyday to those who are not.”

He also compared the legal weed industry’s tax bracket to that of wine or beer, saying a glass of alcohol includes about one or two cents in taxes, whereas taxes on a joint can cost over a dollar.

Haney added that California’s legal cannabis industry appears to be falling behind the cannabis-industry growth of other states such as Michigan, Colorado and Washington, which have lower taxes and friendlier regulations.

“I think that when cannabis was legalized in California, they did not expect that the illegal market would continue to thrive and grow and compete at the scale that it has,” Haney said. “They are operating outside of our laws entirely.

“Until California takes action to put a stop to that, we have to make sure that our businesses that are following the law are not so overly taxed and burdened that they cannot operate at all. This is common sense.”
