Which hallucinogen can be used orally or injected and has a duration of 8-12 hours?

• A. Lsd
• B. Mescaline
• C. Psilocybin
• D. Ecstasy-PCE

Answer: (B)

This item checks knowledge of how long a hallucinogen lasts and the typical ways it can be taken. Mescaline, derived from the peyote cactus, is traditionally taken orally but has also been used in injectable form in some settings. Its effects tend to last about eight to twelve hours, which matches the duration described in the question. This combination of an oral route with a long duration fits mescaline best. By contrast, psilocybin generally lasts around 4–6 hours, and MDMA (ecstasy) is not primarily a hallucinogen and lasts roughly 3–6 hours. LSD can last about 8–12 hours as well, but it is most commonly used orally and injections are not typical, making mescaline the best match for the stated routes and duration.
