Dataset Summary

This dataset is a collection of public cannabis lab test results parsed by CoADoc, a certificate of analysis (COA) parsing tool.

Dataset Structure

The dataset is partitioned into the various sources of lab results.

Source	Observations
Raw Gardens	2,667
MCR Labs	Coming soon!
PSI Labs	Coming soon!
SC Labs	Coming soon!

Data Instances

You can load details, results, and values for each of the dataset files. For example:

from datasets import load_dataset

# Specify the Cannabis Tests dataset.
dataset = 'cannlytics/cannabis_tests'

# Load Raw Garden lab test details.
rawgarden_details = load_dataset(dataset, 'rawgarden_details')

# Load Raw Garden lab test results.
rawgarden_results = load_dataset(dataset, 'rawgarden_results')

# Load Raw Garden lab test values.
rawgarden_values = load_dataset(dataset, 'rawgarden_values')

`sample_id`	"{sha256-hash}"	A generated ID to uniquely identify the `producer`, `product_name`, and `date_tested`.
`strain_name`	"Blue Rhino"	A strain name, if specified. Otherwise, can be attempted to be parsed from the `product_name`.

Each result can contain the following fields.

Field	Example	Description
`analysis`	"pesticides"	The analysis used to obtain the result.

Data Splits

The data is split into training, validation, and test data. Training data is used for training your models. Validation data is used for evaluating your trained models, to help you determine a final model. Test data is used to evaluate your final model.

Dataset Creation

Curation Rationale

Certificates of analysis (CoAs) are abundant for cannabis cultivators, processors, retailers, and consumers too, but the data is often locked away. Rich, valuable laboratory data so close, yet so far away! CoADoc puts these vital data points in your hands by parsing PDFs and URLs, finding all the data, standardizing the data, and cleanly returning the data to you.

Personal and Sensitive Information

The dataset includes public addresses and contact information for related cannabis licensees. It is important to take care to use these data points in a legal manner.

Considerations for Using the Data

Social Impact of Dataset

Arguably, there is substantial social impact that could result from the study of cannabis, therefore, researchers and data consumers alike should take the utmost care in the use of this dataset.

Discussion of Biases

Cannlytics is a for-profit data and analytics company that primarily serves cannabis businesses. The data are not randomly collected and thus sampling bias should be taken into consideration.

Other Known Limitations

The data represents only a subset of the population of cannabis lab results. Non-standard values are coded as follows.

Actual	Coding
`'ND'`	`0.000000001`
`'No detection in 1 gram'`	`0.000000001`
`'Negative/1g'`	`0.000000001`
'`PASS'`	`0.000000001`
`'<LOD'`	`0.00000001`
`'< LOD'`	`0.00000001`
`'<LOQ'`	`0.0000001`
`'< LOQ'`	`0.0000001`
`'<LLOQ'`	`0.0000001`
`'≥ LOD'`	`10001`
`'NR'`	`None`
`'N/A'`	`None`
`'na'`	`None`
`'NT'`	`None`
