For everyone who has tried weed, or are enthusiasts, they have always wondered… can you overdose on weed? You probably can’t smoke yourself to death, but that doesn’t mean there’s no such thing as a marijuana overdose.
The Centers for Disease Control and Prevention in the US also states that while using too much marijuana can cause extreme confusion, emotional distress, increased blood pressure, heart rate, severe nausea, or unintentional injury, a fatal overdose is unlikely.
This happens due to the way our brain functions. When marijuana is injested, chemicals in the plant ride the nervous system to the brain and latch onto molecules called cannabinoid receptors. Those little holding cells influence pleasure, memory, coordination, and cognition, among other functions, which is why getting high affects thinking and behavior.
Cannabinoid receptors are not found in the brainstem areas that control breathing. Thus, "lethal overdoses from cannabis and cannabinoids do not occur," The National Cancer Institute explains.
Marijuana isn't harmless, however. The psychoactive ingredient that gets users high, tetrahydrocannabinol, or THC, is a powerful intoxicant. Having physical abilities and judgments impaired can lead users to put themselves in unsafe situations. Science has also links long-term marijuana smoking with chronic bronchitis and respiratory symptoms like coughing and wheezing
So far no death cases have come forth due to marijuana overdose, too much of it can make users feel uncomfortable. Their heart starts to race, hands tremble, and anxiety strikes. There are things they can do to mitigate a "What I have done?" high. Drink some water to stay hydrated and eat a snack -- preferably one that is ready-to-eat and does not require operating a stove -- to boost your blood sugar.
Marijuana is still a plant, and repeatedly lighting a plant on fire and inhaling it can blacken the lungs as if it were tobacco. However, anyone who would even be a regular pot smoker would not be inhaling as much smoke as a pack-a-day cigarette smoker – and the cannabis user also has plenty of non-smoke alternatives at their disposal.
An access to strong cannabis is a huge factor as well. For most, that just increases your probability of getting higher than planned. But for some people, doctors say the advent of widespread, highly-potent cannabis products increases their risk of an overdose. So, while marijuana has a better safety profile than a lot of other illegal substance, and one may not die, but an overdose is definitely possible.
