He studied ER visits between 2012 and 2016. Monte is also an <a href=\"https:\/\/som.cuanschutz.edu\/Profiles\/Faculty\/Profile\/264\" target=\"_blank\" rel=\"noopener noreferrer\">associate professor<\/a> at the <a href=\"https:\/\/www.cumedicine.us\/providers\" target=\"_blank\" rel=\"noopener noreferrer\">University of Colorado School of Medicine<\/a> on the Anschutz Medical Campus.<\/p>\n<p>Colorado legalized medical marijuana shops in 2009 and recreational marijuana in 2014.<\/p>\n<p>Among the findings:<\/p>\n<ul>\n<li>Nearly 10,000 emergency visits during the study period were tied to patients who were smoking marijuana or ingesting edibles, according to billing codes for the visits. Doctors determined that more than 25 percent of these patients were coping with medical symptoms related to their marijuana use.<\/li>\n<li>Researchers found a three-fold increase in marijuana-related ER visits between 2012 and 2016.<\/li>\n<li>Visits due to edibles were 33 times higher than expected, when controlled for product sales in the state.<\/li>\n<li>Overall, more users sought help after smoking marijuana. They often suffered from nausea and vomiting \u2014 a condition known as cannabinoid hyperemesis. Only about 11 percent of the ER visits tied to marijuana were linked to edibles. But, sales of edibles represent a much smaller share of Colorado\u2019s marijuana market. Therefore, a disproportionate number of patients using edibles seemed to suffer toxic side effects.<\/li>\n<li>Cannabis is now recognized as a risk factor for adverse cardiovascular events.<\/li>\n<li>Users reported more long-lasting effects from edibles compared to smoking or vaping. Sometimes they reported unpleasant psychiatric symptoms.<\/li>\n<li>Deaths tied to cannabis consumption are rare, though the only confirmed deaths associated with marijuana have involved edible products. One young man jumped from a balcony. Another man killed his wife and claimed that an overdose of edibles caused him to act out violently. Another young man died by suicide at a Colorado ski resort after ingesting high doses of edibles.<\/li>\n<\/ul>\n<p>\u201cSome patients will have psychosis, hallucinations or they will hear things,\u201d Monte said. \u201cThe more common thing is acute anxiety, panic attacks, and very high heart rates.\u201d<\/p>\n<p>Tourists visiting Colorado, who don\u2019t have a history of using marijuana edibles, should be especially cautious.<\/p>\n<div class=\"su-callout-box col-xs-6 col-sm-6 right\" style=\"background-color:#dce4e7; color:#2e3b44;\">\n<p><strong>Read more:<\/strong><\/p>\n<ul>\n<li><a href=\"https:\/\/www.uchealth.org\/today\/five-things-you-should-know-about-marijuana-edibles\/\"><strong>5 things you should know about marijuana edibles<\/strong><\/a><\/li>\n<li><a href=\"https:\/\/www.uchealth.org\/today\/is-marijuana-safe-for-older-adults\/\"><strong>Is marijuana safe for older adults?<\/strong><\/a><\/li>\n<\/ul>\n<\/div>\n<p>\u201cThe residents of Colorado are coming to learn that edibles are much more dangerous,\u201d Monte said. \u201cWe see a disproportionate number of tourists \u2013 people outside the state \u2013 that have issues with edibles. That\u2019s likely because they\u2019re taking a little more than they should or they\u2019re stacking doses.\u201d<\/p>\n<p>The study findings prompted leaders at the <a href=\"https:\/\/www.drugabuse.gov\/\" target=\"_blank\" rel=\"noopener noreferrer\">National Institute on Drug Abuse<\/a> and the <a href=\"https:\/\/www.nih.gov\/\" target=\"_blank\" rel=\"noopener noreferrer\">National Institutes of Health<\/a> to alert health experts to the results.<\/p>\n<p>\u201cMonte and colleagues\u2019 findings have important clinical and public health implications,\u201d Dr. Nora D.

And many come from outside Colorado, suggesting that they aren\u2019t regular users.<\/p>\n<figure id=\"attachment_23211\" aria-describedby=\"caption-attachment-23211\" style=\"width: 640px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-23211 size-large\" src=\"https:\/\/uchealth-wp-uploads.s3.amazonaws.com\/wp-content\/uploads\/sites\/6\/2019\/03\/25110428\/dr.-monte-ER-tiny.webp\" alt=\"Headshot of Dr. Andrew Monte in the ER.\" width=\"640\" height=\"363\" srcset=\"https:\/\/uchealth-wp-uploads.s3.amazonaws.com\/wp-content\/uploads\/sites\/6\/2019\/03\/25110428\/dr.-monte-ER-tiny.webp 1200w, https:\/\/uchealth-wp-uploads.s3.amazonaws.com\/wp-content\/uploads\/sites\/6\/2019\/03\/25110428\/dr.-monte-ER-tiny-300x170.webp 300w, https:\/\/uchealth-wp-uploads.s3.amazonaws.com\/wp-content\/uploads\/sites\/6\/2019\/03\/25110428\/dr.-monte-ER-tiny-1024x580.webp 1024w, https:\/\/uchealth-wp-uploads.s3.amazonaws.com\/wp-content\/uploads\/sites\/6\/2019\/03\/25110428\/dr.-monte-ER-tiny-768x435.webp 768w, https:\/\/uchealth-wp-uploads.s3.amazonaws.com\/wp-content\/uploads\/sites\/6\/2019\/03\/25110428\/dr.-monte-ER-tiny-150x85.webp 150w, https:\/\/uchealth-wp-uploads.s3.amazonaws.com\/wp-content\/uploads\/sites\/6\/2019\/03\/25110428\/dr.-monte-ER-tiny-200x113.webp 200w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><figcaption id=\"caption-attachment-23211\" class=\"wp-caption-text\">Dr. Andrew Monte is the lead researcher on a groundbreaking new study that highlights dangers of marijuana use, especially edibles.
