Magic truffles are generally considered low in physical toxicity, but that doesn’t mean they’re without effects or risks. Knowing which side effects are normal, and which situations call for caution, helps you stay calm and safe. This guide gives you an honest overview.
In short: common, usually harmless side effects are nausea, yawning, chills, dizziness and a faster heartbeat. The real risks are mostly psychological (anxiety, confusion, panic) and situational (accidents, mixing with other substances). Psilocybin is not for people with certain medication or a personal or family history of psychosis.
Common physical side effects
These are normal, especially during the first hour, and usually pass on their own:
- Nausea or an upset stomach: common at the start. Eat light beforehand, sip water and give it time.
- Dizziness or light-headedness: sit or lie down for a while, breathe calmly and drink a little.
- Yawning, chills or feeling warm: keep a blanket within reach.
- Dilated pupils and sensitivity to light: dim the lights or wear sunglasses outdoors.
- Faster heartbeat and slightly higher blood pressure: usually mild, but relevant if you have heart or blood pressure problems.
- Muscle tension, restlessness or tiredness: stretching, a short walk or rest helps.
- Headache or fatigue the next day: sleep, water and a quiet day.
Psychological effects to be aware of
- Anxiety or panic: intense emotions or thoughts can feel overwhelming. Usually temporary; a calm setting and a trusted trip sitter make a big difference. See what to do during a difficult trip.
- Confusion and a changed sense of time: normal at higher doses, but a reason never to drive, cycle in traffic or be near water or heights.
- Emotional after-effects: sometimes difficult feelings or memories surface. Take time to reflect and talk about it; seek professional support if it keeps bothering you.
- Lingering visual changes: rarely, people report visual effects that persist after the trip. If that happens, consult a doctor.
Who should not use magic truffles?
- People under 18.
- Anyone who is pregnant or breastfeeding.
- People using medication such as SSRIs, other antidepressants, lithium or other psychoactive medication: interactions can be unpredictable or dangerous.
- People with a personal or family history of psychosis, schizophrenia or bipolar disorder, or other serious mental health conditions.
- People with heart problems or high blood pressure.
When in doubt, always consult a medical professional first.
Don’t mix
Combining truffles with alcohol, cannabis or other drugs increases risks and makes effects less predictable. Alcohol also makes nausea and confusion worse. Keep it simple: one substance, a dose that fits you, in a safe setting.
How to reduce the risk of side effects
- Start with a low dose of a mild variety such as Mexicana, and don’t top up early.
- Eat light beforehand and keep water and small snacks nearby.
- Choose a safe, familiar setting and a sober trip sitter.
- Plan a free day with no driving or obligations.
- Prepare your mindset: see how to prepare for your first trip.
When to seek medical help
Call emergency services (112 in Europe) if someone has chest pain, trouble breathing, a seizure, loses consciousness, is a danger to themselves or others, or if you’re worried in any way. Tell the responders honestly what was taken; they are there to help.
Are microdoses also associated with side effects?
At micro amounts side effects are rare and mild: occasionally restlessness, a slight headache or tiredness. If you notice visual effects, your dose is too high. The same contraindications apply. See our microdosing guide.
Frequently asked questions
Why do magic truffles make me nauseous?
Nausea is a common reaction in the first hour as your body processes the truffles. Eating light, chewing well and sipping water help; it usually passes once the effects set in.
Are magic truffles addictive?
Psilocybin is not considered physically addictive, and tolerance builds quickly, which naturally limits frequent use. That’s also why microdosing schedules include breaks.
Can I take magic truffles if I use antidepressants?
No. Medication such as SSRIs and other psychoactive medication can interact with psilocybin. Consult your doctor; never stop medication on your own to take truffles.
