// Definition
Laboratory analysis of cannabis extracts to detect residual solvents such as butane, propane, hexane, and other hydrocarbons used in extraction. Essential for consumer safety, as improperly purged extracts can contain harmful chemical residues.
// From the Episode
The panel discussed how most labs only test for a limited range of solvents, leaving dangerous gaps. Bubbleman noted that labs test for butane but miss propane and pentane contamination. Mark Renda's work was cited as pushing for more comprehensive testing panels. The group discussed how the lack of standardized testing across states and countries creates inconsistent safety standards.
