# OpenCannabis: Lab Testing Extension
- Version `1.0`
- Status: `RAW`

### Status of this Memo

This specification's current status is considered `RAW`, i.e. pre-`DRAFT`. Distribution of this memo is unlimited.

### Abstract

This document describes an extension to the _OpenCannabis Specification, version 1_, that introduces lab-testing-related
definitions structures, and services that compose, create and reference lab testing.

_"Lab Testing"_ in this context, refers to:
- The chemical components that make up a cannabis product.
- The chemical components and their respective names.
- The media through which the "Lab Testing" is displayed to customers
