Mushrooms
The effects of mushrooms are greatly effected by dose and an individual's sensitivity to psilocybin. For some rare people 1/4 gm of Psilocybe Cubensis (a very small amount) is enough to propel them into full visionary states, with Open Eye Visuals, unpleasant stomach cramps or gas, and other High-Dose effects, while for others the same amount would be barely (if at all) noticeable, possibly causing a slight cold feeling during the first hour and other 'Threshold' effects.
Other effects are paranoia, depression, irritability, anxiety, and suicidal tendencies in mentally unstable users. The effect-time curve of mushrooms, as with other entheogens, are characterized by a short period between ingestion and 'Coming Up', a short (but often experientially long) Coming Up period, a Plateau period, Coming Down, and then After Effects.
Onset: 5-60 minutes
Coming Up: 5-30 minutes
Plateau: 1-3 hours
Coming Down: .5-3 hours
After Effects: 0-6 hours
Threshold Effects : (from .25gm - .75gms P. Cubensis)
Slight cold feeling, mild gas or nausea, nervous-feeling,
slight pupil-dilation, mild visual changes including lights seeming brighter,
lights having a 'starry' look, and noticing movement at the periphery of
vision, giddiness, feeling more emotionally sensitive, and many other effects
related to a change in neurochemistry.
Medium Effects : (0.75gm - 2.5gms P. Cubensis)
'Cold' feeling, gas and/or stomach discomfort, nausea,
pupil-dilation, open-eye visual effects: lights gain auras, star-pattern
effects, rainbowing around lighting, lights seem brighter, often 'more
beautiful', notice movement in periphery, sometimes increased ability to
focus, sometimes reduced ability to focus, visual field 'distracting',
visual field 'entertaining', closed eye 'visuals': normal closed eye 'blobs'
take on patterns, shapes, distinct forms, increased ability to visualize
creatively, spontaneous detailed images, feelings of time-dilation, feelings
of `coming home again' which is often more pronounced for those who have
used mushrooms before, feelings of belonging and connection, increased
emotional sensitivity, increased ability to focus on emotional problems
or memories, chance of becoming 'caught in a loop' thinking / dwelling
on a single thought or feeling (usually negative or painful), realizations
about past feelings, realizations about how to live, gain a new perspective
on current lifestyle and behaviors, feelings of connection with those around
you, noticing things which are normally ignored or taken for granted, feelings
of wonder, spirit, joy, sadness, despair, religious awakening, contentment
and possibly latent psychological crises can come out..
High Dose Effects : (2.5gm - 10gms)
All of the Medium Effects, usually with a significantly
more uncomfortable Coming Up, more pronounced nausea sometimes resulting
in vomiting, sometimes significant mental discomfort associated with feelings
of fear and often times accompanying a "what have I done to myself" or
"how far am I going" thoughts. High Dose Effects are usually characterized
by the closed eye visualizations being significantly more elaborate and
enfolding, religious revelation, spiritual awakening, near death experiences,
loss of self, talking to seemingly external, autonomous entities, extreme
emotional responses, repressed memories coming to life, latent psychological
crises can come to the surface, intense feelings of wonder, connection,
joy, fear. High Dose Effects can also include extreme time-dilation, with
experiences of wall-clock minutes taking an experientially large amount
of time, watching clocks or digital counters where the seconds seem to
take minutes to count off.
