If the participant does not routinely consume caffeinated beverages, he/she must agree not to do so on session days.
• Agree to refrain from using any psychoactive drugs, including alcoholic beverages and nicotine, 24 hours before and after each drug administration. The exception is caffeine. Participants will be required to be either a non-smoker or a non-daily smoker.

• Agree that for one week before each drug session, he/she will refrain from taking any nonprescription medication, nutritional supplement, or herbal supplement except when approved by the study investigators. Exceptions will be evaluated by the study investigators and will include acetaminophen, non-steroidal anti-inflammatory drugs, and common doses of vitamins and minerals.

You may not qualify if:

• Women who are pregnant (as indicated by a positive urine pregnancy test assessed at intake and before each drug session) or nursing; women who are of child-bearing potential and sexually active who are not practicing an effective means of birth control.
• Cardiovascular conditions: coronary artery disease, stroke, angina, uncontrolled hypertension, a clinically significant Electrocardiogram (ECG) abnormality (e.g., symptomatic atrial fibrillation), or Transient Ischemic Attack (TIA) in the past year

• Currently taking psychoactive prescription medication on a regular (e.g., daily) basis
• Currently taking on a regular (e.g., daily) basis any medications having a primary centrally-acting pharmacological effect on serotonin neurons or medications that are Mono amine Oxidase (MAO) inhibitors. For individuals who have intermittent or PRN use of such medications, psilocybin sessions will not be conducted until at least 5 half-lives of the agent have elapsed after the last dose.
