title_body: Tequila worms - to eat or not to eat - that is the question?
upvoted_answer: Not all types of tequila contain a tequila worm. The tequila worm or as it should be known as the Mezcal worm is normally only found in Mezcal (tequila). 
  
  
    The worm is reserved for a drink known as Mezcal, which, according to some, is tequila’s big brother. But the two spirits are entirely different. Tequila is distilled from any number of natural Mexican plants and can bear the name as long as the finished product consists of at least 51% agave. Mezcal must be 100% agave. - Should You Eat the Tequila Worm?
  
  
  Most people would not eat the mezcal worm, but in some cultures it is quite acceptable.
  
  
    There are no proven side effects that come with consuming a Tequila worm. While the worm is popularly called the tequila worm, it is only found on the bottom of a bottle of mezcal, a variety of tequila obtained from distilling blue agave and similar plants. The meriposa worm is grown on agave from which mezcal is made, and when a worm is added to the mezcal, it is known as mezcal con gusano.
    
    Consuming the worm after drinking mezcal is a popular tradition among many communities, but it is not clear where the tradition originated. Some believe that the adding the worm in a bottle of mezcal signifies the purity of the alcohol, as it hinders the disintegration of the worm. Others believe that it is merely a marketing strategy among Mexican liquor producers.
    
    While it's documented in media that the eating the worm causes hallucinations, this has yet to be medically proven. The worm is pickled in alcohol for more than a year and is made sure to be free to pesticides, before being added to mezcal. It is also a popular delicacy in Mexican restaurants, and is said to have positive psychological effects. - What happens when someone eats a Tequila worm?
