- Induces a feeling of general numbness, making movement (e.g., walking) feel like a seamless floating experience.
Peak character

- Promotes a feeling of general contentment, with anxieties dissipating.
- Can be multifaceted, allowing different aspects of the experience to be solicited at will at certain doses.
Negatives / side effects
- Reports of tragic outcomes associated with the drug's use.
- Should always be approached with care and never binged.
