25x-NBOMe
Members of the NBOMe series have been linked to numerous overdoses and fatalities.[1][2][3]
It is strongly discouraged to insufflate (snort) or take higher doses of these compounds. Please see this section for more details.
25x-NBOMe is the general form of the NBOMe series of psychedelic phenethylamines. The series has nearly no history of human use prior to 2010 when some of the first compounds became available for purchase from online research chemical vendors.
It is often sold as LSD, but one key difference between 25x-NBOMe and LSD is that NBOMe is only active when taken through a sublingual or insufflated route. This means that in order to get the full effects, 25x-NBOMe blotter paper must be lightly chewed on for 20+ minutes and never immediately swallowed. Insufflation, however, is not recommended; reports of people suffering dangerous and often fatal overdoses due to this route of administration have been surfacing.
Chemistry
In a comparison of 25x-NBOMe and 2C-x chemicals, each 25x-NBOMe molecule is a serotonergic N-benzyl derivative of the corresponding 2C-x molecule. This change in structure results in an increase in potency. It differs from the corresponding 2C-x structurally through a substitution on the amine (NH2) with a 2-methoxybenzyl (BOMe) group. The addition of this BOMe group also causes most of the compounds to have relatively the same duration, regardless of how long the 2C-x counterpart lasts.

Health effects, potential addiction and tolerance
The 25x-NBOMe chemicals, as with many other serotonergic psychedelics, should not be taken in combination with SSRIs (selective serotonin reuptake inhibitors) or tricyclic antidepressants in general to avoid serotonin syndrome, a potentially life-threatening condition in which an abundance of serotonin is built up the body, causing many physical and cognitive health problems.
Legal issues
- USA: In the US, some of the 25x-NBOMe chemicals are listed as Schedule I substances and all analogs under the Federal Analog Act.
