Talk to patients about new data linking regular cannabis use with serious cardiovascular adverse effects. As the DEA considers the rescheduling of cannabis, and access is greater than ever, it’s important to remind patients that regular use doesn’t come without risks.
A recent study in adults 18-74-years-old suggests that daily cannabis use is linked with a 25% increased chance of heart attack and a 42% increased chance of stroke when compared with nonuse, regardless of cigarette smoking history. This chance decreases as cannabis is used less frequently – a point worth highlighting to daily users. Most participants in this study reported smoking cannabis, so it’s unclear if this link also applies to other forms, such as edibles. But previous studies have linked edible products containing very large doses of THC, 50 mg or more, to both heart attack and abnormal heartbeat.
In addition to cardiovascular concerns, chronic cannabis use also poses a variety of other safety concerns, including potential respiratory problems, dependence, and serious conditions like cannabinoid hyperemesis syndrome (CHS). Furthermore, cannabis and cannabis-containing products continue to increase in potency. Keep an open dialogue with patients about their cannabis use – discussing both why they use it and how often. Note that chronic and daily use appears to be linked with the most serious adverse effects.
