2C-P (4-propyl-2,5-dimethoxyphenethylamine) is a psychedelic phenethylamine first described by chemist Alexander Shulgin in his book PiHKAL: A Chemical Love Story. 2C-P is usually taken orally or insufflated. It is one of the most potent phenethylamines, with a typical dose in the range of 3-10 mg. 2C-P has both hallucinogenic and entactogenic properties, and is often described as having a relatively slow onset followed by an intensely psychedelic peak that persists longer than with other similar phenethylamines.

Introduction to 2C-P

[​IMG]Initially synthesised by Dr. Alexander Shulgin, 2C-P is considered to be a strong psychedelic phenethylamine which possesses stimulant type effects as well. 2C-P has been shown to produce a variety of intense hallucinogenic type effects ranging from drastic changes in consciousness and perception, to open and closed eye visuals. 2C-P is considered to be one of the strongest 2C-x compounds dosage for dosage, rivaled only by 2C-TFM. 2C-P has been known to have an extremely long time of onset, ranging between 3-5 hours after consumption before any of the compounds psychoactive effects begin to occur.

On average 2C-P last between 10-16 hours in duration and even longer if additional doses are taken after the compounds initial administration. 2C-Ps main psychoactive effects are derived from its ability to agonist the 5HT2A serotonin receptors in a similar fashion to that of many of the other 2C-x compounds. 2C-P is said to have effects similar to that of 2C-E, except longer in duration.

Ways of administration

2C-P is most commonly administered through oral consumption due to the large quantity of serotonin receptors which are found to line the walls of the gastrointestinal tract. 2C-P can also be administered via insufflation, however one will experience extreme pain if the compound is administered through this route as is the case with all of the 2C-x compounds.

The dangers of 2C-P

Prior to administering a dose of 2C-P one should be aware of the dangers associated with compound.
  • 2C-P is considered to be a research chemical, thus the long term and short term effects/side effects of the compound have yet to be determined due to a lack of formal trials.
  • 2C-P is considered to be a central nervous stimulant, users whom have a known physical illness should avoid this compound as it may instigate the symptoms of said physical illness.
These are the dangers common to all psychedelic drugs:

Accidental injury.
When on a psychedelic drug, it is easier to accidentally injure yourself. Also because of the disorientating and potentially delusion inspiring nature of the experience, you could be lead to inflict harm on others or yourself. People have fallen off rooftops, run into traffic, attempted to throw people off rooftops as 'sacrifices', drowned, and so on. The best way of protecting against this is to have a friend with you who is sober to look after you and handle any negative situation that might arise.

Bad trips. A bad trip is a negative psychedelic experience. It can range from a mildly negative feeling of anxiety/discomfort, to full-blown psychosis. Bad trips usually ruin a psychedelic experience for the tripper and everyone else. Most bad trips are manageable, just very uncomfortable and difficult. Some are extreme and unmanageable though. It's not uncommon for a bad trip to result in lingering psychological issues. Usually just a few days of negative emotions and anxiety. Sometimes, however, a week or so of serious anxiety, destabilized mental state and impaired functioning is possible. On very rare occasions, a month or two of severely diminished functioning, traumatized mental state, depression & crippling anxiety can occur. More information on bad trips can be found here. The best way of avoiding a bad trip is having the correct set and setting.

Permanent psychosis. Psychedelics are believed by researchers not to cause permanent psychosis, however they could trigger a latent mental illness in someone who was already predisposed to it, or make existing mental illnesses worse. If there is a history of mental illness in your family, you are more likely to be predisposed. Everyone is at some risk, however.

PTSD, anxiety disorder, depression & depersonalization. There are anecdotal reports of the trauma inflicted by some bad trips leading to depression and anxiety which while usually temporary, could potentially develop into lasting disorders. While no different to the potential of any traumatic event to cause lasting disorders, nonetheless this is a danger of psychedelic drug use.
