As more people choose to be alcohol-free, another type of mind-altering product is gaining popularity. [1] Cannabis-infused beverages, such as THC sodas, shots, and cocktails, have become an enticing alternative.

But just because these adult beverages are alcohol-free doesn’t mean they’re risk-free. 

Effects of THC-infused drinks

While THC-infused drinks may make some people feel relaxed and euphoric, others may become anxious, dizzy, or paranoid.

“Occasional use won’t cause any major health issues for most adults, but regular or heavy use can potentially affect memory, mood, and motivation,” says Sylvie Stacy, MD, MPH, an addiction medicine specialist and the Chief Medical Officer of Rehab.com.

Regular, long-term use of THC drinks—especially at high doses—“has been linked to cognitive impairment, dependency, and even cannabis hyperemesis syndrome, which causes severe nausea and vomiting,” says Pamela Tambini, MD, an internal medicine and addiction medicine physician at Engage Wellness in Acton, MA.

A small percentage of people may become addicted, Dr. Stacy adds. Though cannabis use disorder is uncommon, recent estimates by the CDC suggest that three in 10 people who use cannabis struggle with the disorder. [2]

“I’ve seen patients in my clinic struggle with their job, relationships, or just being able to be productive day-to-day as a result of problematic cannabis use,” Dr. Stacy says.

According to Dr. Tambini, unlike cannabis consumed through smoking or vaping, THC-infused beverages take longer to kick in, typically between 30 minutes to 2 hours.

“That delay can lead to people drinking more than they should before realising the effects, increasing the risk of overconsumption,” Dr. Tambini tells MDLinx. 

One of the main concerns about these beverages is the lack of regulation, which, according to Dr. Tambini, is all over the place. “Some states require strict testing and labelling, while others have little oversight,” she says.

As such, the potency of various products varies, and some sodas might even contain pesticides, solvents, or unlisted cannabinoids. “Consumers need to be cautious and do their research before diving in,” Dr. Tambini says.

THC beverages vs alcoholic beverages

It’s crucial for people to understand that their bodies will metabolise THC beverages differently than wine or beer. [3] For those who are curious about THC drinks, it’s best to purchase products from a certified dispensary.

“When you do that, there’s a better chance the THC content is accurate and the product has been tested,” Dr. Stacy says. Then, “start low and go slow,” Dr. Tambini adds.

Try no more than 2.5 to 5 milligrams of THC, according to Dr. Tambini. Remember, that delayed onset—whether 30 minutes or a couple of hours—can trick you into thinking you need more before the drink fully kicks in, she adds.
