ELi5: Why does weed give some people anxiety while for others it relieves it?

Some people get extremely anxious when high while others are able to relax and have fun, why is this?

ELI5 answer: In short, it enhances what's already there, which is why experienced recreational drug users always talk about "set & setting". The "set" is your mindset and the "setting" is your surroundings.

If you already have anxiety and stress or if you're in a setting which isn't enjoyable or just negative all-around, all of that is going to get amplified.

Conversely, if you're relaxed and having a good time and in a warm & comfortable place you're more likely to have a positive experience.
