Hallucinogenic substances like psilocybin can have short-term negative effects, but these are most likely associated with macro-doses, as microdoses, as suggested in our microdosing protocol, are sub-perceptual doses.
Specific short-term effects of macro-doses of hallucinogens include:
Increased blood pressure, breathing rate, or body temperature
Loss of appetite
Feelings of relaxation
Paranoia — Extreme and unreasonable distrust of others
Psychosis — Disordered thinking detached from reality
*These effects are associated with macro-doses and journeys and not with microdoses.
