Blue Meanie.

Serving guide

Start low. Potency varies from batch to batch, and even between the cap and stem of one mushroom.

• If it’s your first time, or a new strain or batch, stay at the light end.
• Grinding and mixing a whole pouch evens out the strength from one serving to the next.
• Weigh servings on a scale that reads to 0.01 g. Don’t eyeball them.
• Strains rated 8/10 or higher on our potency scale: start at the low end of any range.

Blue Meanie is Panaeolus cyanescens, a different species from our other mushrooms. Don’t assume a cubensis serving carries over; start at half your usual amount.

Timing

• Onset: usually 20–60 minutes; longer after food, and often longer with chocolate.
• Peak: about 1–2 hours in.
• Duration: about 4–6 hours, with after-effects for up to 8.

Don’t take more because you “don’t feel anything yet”. Wait the full 2 hours.

Don’t combine with

• Lithium. In an analysis of online reports, nearly half of people who combined lithium with a classic psychedelic described a seizure.
• MAOIs, including some antidepressants and harmala brews such as ayahuasca. They can change the effects in ways that are hard to predict.
• Antidepressants (SSRIs, SNRIs and others). These can change or blunt effects. Never stop or change a prescribed medication without talking to your doctor.
• Alcohol, cannabis or other substances. They make effects less predictable.

Avoid psilocybin if you

• have, or have a close family history of, schizophrenia, schizoaffective disorder, severe bipolar disorder or borderline personality disorder
• have a heart condition or high blood pressure (psilocybin raises heart rate and blood pressure)
• are pregnant or breastfeeding
• are under 18

Never drive or operate machinery for the rest of the day.
