In addition to vaping’s effects on a person’s long term health, this marijuana consumption method may create dangerous short-term effects for certain people.

A 2018 study from Johns Hopkins Medicine, for example, found that infrequent cannabis users may get higher from vaping weed than from smoking it. “What our study suggests is that some people who use cannabis infrequently need to be careful about how much cannabis they use with a vaporizer, and they should not drive, even within several hours after use,” Ryan Vandrey, the study’s lead author, said in a press release.
With combustible smoking methods, users get a general idea of how much marijuana they are consuming. While some vape pens signal when a user has reached a specific dose, more often than not a person can’t see the physical marijuana and may therefore vape without realizing how much marijuana they actually consume. As a result, they may get higher than they would from combustible methods. A small 2018 study in JAMA found this to be true. After researchers had some people use vapes and others smoke marijuana, they discovered the vape users felt higher and some even vomited or hallucinated after vape use.
What’s more, infrequent users who vape could experience greater feelings of anxiety, nausea, vomiting, and hallucinations, the researchers found. Since vape use could impair users and put them and others in dangerous situations, people should evaluate their circumstances before using one of these devices and consuming marijuana in general.
