To tell you the truth, an overdose from cannabis itself is extremely unlikely to kill you; however, you can certainly consume too much THC and spend several hours in extreme discomfort.

What “Overdose” with a THC Vape Means

When we speak of overdose with drugs such as alcohol and opioids, we typically refer to a dangerous or potentially lethal situation in which breathing or heart function is compromised. Cannabis vape products do not follow the same pattern. Most of the time, people experience acute THC overconsumption – they ingest more THC than their body’s nervous system can handle at once. The typical signs include:

  • A rapid heartbeat, tremors, dizziness, and/or the sensation that you may be going to pass out
  • Extreme anxiety, paranoia, or a general sense of dread (the feeling that something is horribly wrong)
  • Severe nausea, dryness in the mouth, confusion, and/or difficulty speaking or focusing

These symptoms are frightening, but in a healthy individual, they should subside as THC is metabolized by the body over a period of a few hours.

Why Does it Happen More Often with Vapes?

  • Fast Delivery – THC enters the brain almost instantly, so you could end up taking multiple puffs before the first one has even started working.
  • High Potency – Many cartridges contain 60-90% THC, significantly stronger than most traditional flowers.
  • Low Visibility – There is little to no odor/smoke involved, making it easy to miscalculate how much THC you’ve consumed.

There is a greater likelihood of experiencing negative effects if you have a low THC tolerance, if you are using again after a long break from cannabis, if you are mixing cannabis with other substances (alcohol, energy drinks), or if you are genetically predisposed to experiencing extreme levels of anxiety/panic.

An Example of a “Softer” Vape Profile

Below is an example of a well-balanced product like the ones you would find when searching through Canna City.

CBD does not “counteract” THC, but in many individuals it tends to soften the experience and lower the potential for extreme anxiety.

Reducing Your Risk of Overconsuming

The following habits can greatly decrease your chances of consuming too much THC:

  • Start Low – Take one or two small puffs and wait at least 10-15 minutes before deciding whether you need more.
  • Select products that clearly label their potencies and, if available, balanced ratios of THC/CBD instead of only going after the highest percentage.

In the event that you feel you have overconsumed THC, remember that it will pass, move to a quiet and safe area, drink some water, breathe slowly, and if you are experiencing severe discomfort, seek medical attention – caution is always the best course of action.

Could I Get Overdose With Weed Vaping? Real-World Example

“The first time I used a strong vape, I just kept hitting it because I did not feel anything right away. About ten minutes into it my heart was pounding and I was convinced something was wrong. Now I only hit one or two times and wait for a bit.”

Safe Exploration

Understanding the strength of the vape you are using, consuming in moderation, and selecting products that meet your THC tolerance are the fundamental principles of harm reduction.
