A method of drug administration involving the insertion of a substance, typically in powder form, into the rectum. This route allows the substance to be absorbed directly into the bloodstream via the rectal mucosa. The effects are generally felt more quickly than oral ingestion but may be less intense than intravenous administration. An example includes utilizing a small syringe without a needle to introduce a measured amount of a substance into the rectum.
This administration route offers an alternative to swallowing or injecting drugs, and it can be perceived as less invasive than intravenous use. Some may choose this method due to the potential for faster absorption compared to oral ingestion, while others might opt for it to avoid the risks associated with needle use. Historically, the practice has been associated with recreational drug use but is also employed in medical contexts for specific medications when other routes are not feasible or desirable.
