I'm wondering if there is a possibility of brain-damage after I took a small amount of magic mushrooms.
Hello and thank you for your question.
No it may not cause a brain damage but can surely give you hallucinations.
Magic mushrooms can distort colours, sounds and objects. They can make you feel as if your senses are mixed up so that, for example, you think you can hear colours and you can see sounds. Some people can feel more emotionally sensitive or more creative or feel enlightened.
It can make it feel like you're dreaming when you're awake.
If you have any mental health issues, magic mushrooms can make them worse.
Your perception of your body and the world around you can be distorted, which means you may be at risk because you’re not in complete control of what you're doing.
This effects would remain until it is in your system than you will be back to the normal condition.
As you had small amount it is unlikely that you would experience any side effects.
Please get back to me if you have any further questions. Thank you.
