It’s difficult to say whether or not marijuana helps anxiety or causes it. It depends on a few factors. First and foremost, your mental state and the environment you’re in when using marijuana play a big role in how you react. Marijuana and anxiety can go hand-in-hand for some people. You may not get a pleasant or relaxing experience when using it. In fact, your experience could be quite the opposite. Many people feel that marijuana can bring symptoms of anxiety or heighten their existing anxiety, particularly if they use it in a situation that isn’t pleasant or trying to conceal their use of the drug.
