Novus Medical Detox Center: Colorado Study Findings Spotlight Inherent Dangers of “Cannabis Tourism”

Share Article

Following Colorado’s legalization of recreational marijuana and recent influx of weed-seeking visitors, Novus Medical Detox Center warns the trend has resulted in increased hospital visits and growing health risks for cannabis tourists.

Kent Runyon of Novus Medical Detox Center comments on Colorado's "weed tourism" boom.

In light of these consequences, I would advise avoiding recreational drug use of any kind. A short-term high simply isn’t worth the risk of illness, injury or in the opinion of some, even death.

Several studies have revealed the rising dangers of “marijuana tourism” since Colorado legalized recreational cannabis use, including increases in pot-related emergency room (ER) visits, hospitalizations and traffic deaths (1, 2). Novus Medical Detox Center, a leading Florida-based drug treatment facility, urges prospective “weed tourists” to beware of the risks and advocates for expanded awareness and education campaigns.

A report published in 2015 found that marijuana-related ER visits in Colorado more than doubled from 2011 to 2014—increasing 122.7%, from 8,197 to 18,255—while marijuana-related hospitalizations grew 81.4%, from 6,305 to 11,439, over the same period (1). A subsequent study compared the rates of drug-related ER visits for both in-state and out-of-state residents at Colorado hospitals. Though both groups showed a steady increase from 2011 to 2014—65.6% for in-state residents and 117.3% for non-residents—the rates for out-of-state visitors were significantly higher in 2014: 163 per 10,000 ER visits versus 101 for Colorado residents (2).

Despite the total number of Colorado traffic deaths falling from 535 in 2006 to 488 in 2014, the number of fatalities with operators testing positive for marijuana jumped 154%, from 37 to 94, during the same period (1). In 2014, 1 in 5 Colorado traffic deaths was linked to marijuana (1).

Some experts have attributed these clinical consequences to the heightened potency of Colorado’s commercially grown cannabis (3). Two or three decades ago, the tetrahydrocannabinol (THC) levels of marijuana were “well below” 10%; but recent lab tests found that Colorado’s retail cannabis had average THC levels of 18.7%, with many samples “in the high 20s” and some at 30% or above (4). The lab also found ample evidence of contaminants; some marijuana buds were infested with up to a million fungal spores, and some contained solvents such as butane (4).

“The legalization of medical and recreational marijuana has led people to think of it as an innocuous and even beneficial drug; however, this perception has caused many to overlook the associated risks,” explained Kent Runyon, Vice President of Community Relations and Chief Strategy and Compliance Officer for Novus Medical Detox Center. “A growing number of visitors are traveling to Colorado to legally purchase and partake in weed, but statistics show that a number of them are ending up in emergency rooms.”

According to Runyon, the first step in reversing this trend is to raise awareness and undertake educational efforts. The Colorado Department of Public Health implemented a “Good to Know” program to inform residents of the risks and side effects of marijuana use (5), which may help explain the lower rates of ER visits for in-state versus out-of-state residents. Runyon advocates for similar programs to be expanded nationwide, particularly in states bordering Colorado and other states with legalized recreational cannabis use (Alaska, Oregon and Washington).

Runyon also asserts that there is no such thing as a “harmless” drug, explaining that even doctor-prescribed medicines can cause harm if taken in combination with other medications, beyond the daily dose prescribed, and/or taken for longer than recommended. He cites America’s current opioid painkiller epidemic and rising overdose deaths as a case in point, and notes that marijuana use has been a factor in many individuals being sent to the ER with cyclic vomiting, acute intoxication, anxiety, psychosis and motor-vehicle collision injuries (5).

“In light of these consequences, I would advise avoiding recreational drug use of any kind. A short-term high simply isn’t worth the risk of illness, injury or in the opinion of some, even death. But I appreciate that there are differing viewpoints on the risks associated with marijuana. Therefore, I urge anyone who is entertaining using marijuana while traveling to a state where it is now legal to do their own research beforehand. Don’t disrupt a vacation with an unnecessary trip to an emergency room as many others have done,” concluded Runyon.
