5 Ways Pot Can Kill You, Or Not
You’d need to smoke 200+ joints to OD on marijuana — but there are still risks.
‘This Week’: Marijuana Legalization
Feb. 4, 2014 — intro: It’s been compared to alcohol and tobacco, but research into marijuana and its long-term health effects is still a bit, well, green.
Some experts say smoking weed can have lethal effects on the body and mind, while others say it’s less toxic and addictive than booze and cigarettes and should be legalized nationwide.
While it would take an estimated 240 joints to overdose on marijuana, there are at least five other ways the drug can put your at risk (not counting being crushed by your stash, like this Brazilian trafficker).
Here’s a breakdown of what we know and don’t know about the health effects of marijuana – a drug that roughly 5.4 million Americans use on an almost-daily basis.

Some studies have equated a single joint to as many as 20 cigarettes in terms of lung damage, causing chronic coughs and predisposing users to dangerous lung infections.
But when it comes to cancer risk, the jury’s still out: “It is not yet known whether marijuana smoking contributes to risk for lung cancer,” according to the National Center on Drug Abuse.

Some studies suggest marijuana use can increase your risk of a heart attack, particularly in the first hour after use. But one 15-year study found no such effect. The drug is also linked to cannabis arteritis – an arterial disease that can lead to amputations.

“It disrupts the development of circuits,” said Dr. Paula Riggs, a substance abuse expert and professor of psychiatry at the University of Colorado. “The latest study shows that regular use when you’re an adolescent is associated with a 6-to-8 point reduction in IQ.”
quicklist: 4 category: Ways Pot Can Kill You, Or Not title: It Can Crush Your Concentration url: text: Weed can also interfere with judgment, concentration and coordination, which can have deadly effects on the road. Marijuana use among drivers more than doubles the risk of being in an accident, according to the National Institute on Drug Abuse.
quicklist: 5 category: Ways Pot Can Kill You, Or Not title: It Can Mess With Your Mood url: text: Marijuana use has been linked to depression, anxiety and even suicidal thoughts, according to the National Institute on Drug Abuse. In high doses, the drug can also trigger hallucinations and paranoia and worsen the symptoms of schizophrenia.

Popular Slang Searches
As you’ve probably noticed, the slang synonyms for ” term ” are listed above. Note that due to the nature of the algorithm, some results returned by your query may only be concepts, ideas or words that are related to ” term ” (perhaps tenuously). This is simply due to the way the search algorithm works.
You might also have noticed that many of the synonyms or related slang words are racist/sexist/offensive/downright appalling – that’s mostly thanks to the lovely community over at Urban Dictionary (not affiliated with Urban Thesaurus). Urban Thesaurus crawls the web and collects millions of different slang terms, many of which come from UD and turn out to be really terrible and insensitive (this is the nature of urban slang, I suppose). Hopefully the related words and synonyms for ” term ” are a little tamer than average.
The Urban Thesaurus was created by indexing millions of different slang terms which are defined on sites like Urban Dictionary. These indexes are then used to find usage correlations between slang terms. The official Urban Dictionary API is used to show the hover-definitions. Note that this thesaurus is not in any way affiliated with Urban Dictionary.
Due to the way the algorithm works, the thesaurus gives you mostly related slang words, rather than exact synonyms. The higher the terms are in the list, the more likely that they’re relevant to the word or phrase that you searched for. The search algorithm handles phrases and strings of words quite well, so for example if you want words that are related to lol and rofl you can type in lol rofl and it should give you a pile of related slang terms. Or you might try boyfriend or girlfriend to get words that can mean either one of these (e.g. bae). Please also note that due to the nature of the internet (and especially UD), there will often be many terrible and offensive terms in the results.
There is still lots of work to be done to get this slang thesaurus to give consistently good results, but I think it’s at the stage where it could be useful to people, which is why I released it.
