You can feel the effects of mushrooms in about 30 minutes and they last about 3 to 6 hours. The effects are strongest (the peak) during the first 3 to 4 hours.
Mushrooms can change the way you see, smell, hear, taste, and touch (e.g., you might think you can see music or hear colours). Your body might feel very heavy or very light. You might feel like you are having a magical or religious experience
