While there has never been a case of a person having a fatal overdose due to cannabis use, there can be unpleasant effects. There have been cases of people experiencing such adverse reactions as anxiety, paranoia, and disorientation. Due to the way that the brain interacts with the marijuana, the effects of marijuana are temporary and should pass within a few hours of use. The best way to deal with someone suffering from a negative reaction to cannabis is to keep them calm, try to reassure them that the experience they are having is temporary and will pass eventually.
These negative reactions to marijuana are more likely to happen to users that are unfamiliar with the effects of marijuana or users that have taken a large amount. Additionally, even those that are used to smoking have occasionally reported unpleasant symptoms. It’s not uncommon for someone to experience dizziness, nausea, or headaches after taking a large dose of marijuana. There are even some individuals that regularly have these symptoms, similar to the way someone might have an allergic reaction to a medication.
The negative experiences that an individual may have are less common when the person has inhaled the marijuana, compared to someone that has orally ingested the marijuana. This is due to the fact that when someone smokes cannabis, they will be able to sense immediately if they have had too much or are beginning to have a negative reaction to it. Also, ingested marijuana can take a longer time to reach the body, resulting in people eating more edible cannabis treats to try to feel the effects. When eating edible marijuana snacks, if a person is not sure how much of a dosage is in each piece, they should start with a small amount and give it a half hour or so to judge the effects.
In the late 1800s and early 1900s, when the effects of marijuana were not as widely understood, there were a lot more cases of bad reactions to marijuana. Back then, cannabis was more often used for medicinal purposes and the doctors were not always aware of the dosage they were giving their patients.
Today we understand a lot more about the way marijuana interacts with the brain. We understand that the effects are only temporary and will surpass in a number of hours after taking a dose. Most people that are experiencing a bad reaction to marijuana will not need any type of medical treatment in order to get better. If you are with someone that is having a bad experience, you should try to soothe them by keeping them calm and explaining that the effects will go away within a few hours. There are rare cases of individuals who do need to seek medical treatment after a large dosage of marijuana; though, those individuals typically have some type of pre-existing mental condition. For people that suffer from schizophrenia or bipolar disorder, it may be best to avoid the use of marijuana.
