Don’t Try to Drink Cactus Water
One that seems to be common knowledge is that you can discover drinkable water inside a cactus if you ever find yourself stuck in the desert. This is depicted in a number of Western films, including The Book of Boba Fett and Avatar: The Last Airbender, as well as in cartoons. Should you heed Boba Fett's survival suggestions? Not really, but it only serves to confirm the dangerous notion that this is a real issue that people already have.
It is not a myth that there is liquid inside of some cacti; for example, the barrel cactus has liquid inside of it. Yet, drinking it can worsen an already severe situation. This water isn't pure; it contains cactus alkaloids and other acidic substances. It can induce severe stomach ache, diarrhea, and even joint and bone pain when consumed. A small amount of alcohol may help you live longer, but excessive use may shorten your life by accelerating your dehydration. In the end, not drinking it at all is a horrible decision.
