Chaga mushrooms are not considered psychedelic. While they do contain various bioactive compounds, including betulinic acid, polysaccharides, and antioxidants, these compounds do not have psychedelic effects like those found in certain other mushrooms, such as psilocybin-containing species.

While Chaga mushrooms are generally considered safe for most people when consumed in moderation, there are certain individuals who may need to exercise caution or avoid Chaga altogether. Here are some groups of people who should consult with a healthcare professional before taking Chaga supplements:

• Pregnant or breastfeeding women
• People taking medications - Chaga may interact with certain medications, such as blood thinners or medications for diabetes. If you're taking prescription medications, especially those that affect blood clotting or blood sugar levels.
• Individuals with autoimmune diseases - Chaga may stimulate the immune system, which could exacerbate symptoms in individuals with autoimmune conditions such as rheumatoid arthritis, lupus, or multiple sclerosis
• Those with allergies - Some individuals may be allergic to Chaga mushrooms or other ingredients in Chaga supplements.
• People with bleeding disorders - Chaga may have blood-thinning properties, which could increase the risk of bleeding in individuals with bleeding disorders or those taking blood-thinning medications.
