2C-D (4-methyl-2,5-dimethoxyphenethylamine) is a psychedelic phenethylamine first described by chemist Alexander Shulgin in his book PiHKAL: A Chemical Love Story. 2C-D is usually taken orally or insufflated with a typical dose in the range of 10-40mg. 2C-D is reported to be far less intensely hallucinogenic and entactogenic than other phenethylamines. It has been explored as a potential nootropic at very low doses.
Introduction to 2C-D2C-D was initially synthesised in 1970 by a team of scientists at the Texas Research Institute of Mental Sciences. Its activity in humans however, was not discovered until Alexander Shulgin began experimenting with the compound in his personal laboratory, where it was determined that 2C-D was in fact a moderately strong psychedelic hallucinogen. Mr.Shulgin himself described 2C-D as being "pharmacological tofu".

Ways of administration2C-D is commonly administered through oral consumption, providing a greater range of effects as the result of an abundant amount of 5-HT serotonin receptors which line the walls of the gastrointestinal tract. 2C-D has also been proven to be effective through intranasal insufflation, though this route of administration may prove to be extremely painful.

The dangers of 2C-DThere are several dangers associated with 2C-D that one should be aware of prior to administering the compound.
These are the dangers common to all psychedelic drugs:
- 2C-D is a research chemical, thus its short-term and long-term effects have yet to be fully determined through formal studies.
- 2C-D acts as a central nervous stimulant, thus users whom have a known physical illness should avoid this compound as it may potentiate such symptoms resulting in an undesirable and possibly dangerous reaction.
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.
