How can PCP be administered?

The correct answer indicates that PCP (phencyclidine) can be administered orally, smoked, or snorted, reflecting its various methods of consumption. This versatility is significant in the context of drug administration, as it influences not only the onset and intensity of effects but also the potential for abuse and dependence.

When PCP is taken orally, it undergoes a different metabolization process compared to other routes, leading to delayed effects, while smoking or snorting it allows for quicker absorption into the bloodstream, resulting in more immediate psychoactive effects. This characteristic of PCP contributes to its varied use as recreational drug users may opt for different methods based on their desired experience.

Other methods of administration are less widely recognized or used for PCP, which is why the remaining options, such as intravenous or subcutaneous injections, are not typically associated with this particular drug. Understanding the routes of administration aids in comprehension of both the drug's pharmacology and the implications for treatment in cases of abuse or overdose.
