Approximate frequency of occurrence scale
This rating scale serves as a very approximate indication of the frequency of occurence that a subjective effect is likely to manifest at within the range of a specific dosage. It is primarily used within our substance documentation articles that can be found listed here.
- Rare - At this dosage, the effect typically only occurs spontaneously for a small percentage of people and may never arise for many people no matter how many times they use the substance.
- Uncommon - At this dosage, the effect typically occurs for people eventually over the course of multiple trips but will usually be absent from the experience more often than not.
- Common - At this dosage, the effect typically occurs for people during most of their experiences with the substance but is often a little inconsistent in its occurrence.
- Frequent - At this dosage, the effect typically occurs for most people during all of their trips to the extent that it is unusual if it does not happen.
- Near universal - At this dosage, the effect typically occurs for all people during all trips although there is always the possibility that it may not happen for certain individuals.
