Experience

Primary effects

  • Produces a mild buzz at 50mg leading to a full effect at 100mg+ orally.
  • Gradually increased intensity and produced a very nice ride when insufflated, while maintaining functionality.

Peak character

  • Initially perceived as nice, clean, and providing an enjoyable buzz.

Negatives / side effects

  • Easy to fall into a redosing trap, leading to quickly increasing dosages and a ceiling of effects.
  • Increasing body load and diminishing returns; the positive effects were eventually not worth the aftermath.
  • Suspected to cause cold/flu-like symptoms, inflammation, and have detrimental effects on the immune system. Can linger in the body longer than expected.

Aftereffects / comedown

  • Residual stimulation can prevent sleep without aid (e.g., benzodiazepines).
