#3 Pesticides and Heavy Metals
Hemp and cannabis extracts need to be tested for pesticides and heavy metals. Just like with food crops, regulators want to make sure that consumers aren’t exposed to dangerous substances. The CBD COA will include a pesticide and metal analysis to confirm whether or not there are dangerous levels of pesticides or metals in an extract. Like with the solvent test, the extract will be given either a pass or fail.
Metals – Heavy metals such as arsenic, mercury, and lead are a common hazard in agriculture. They often infect plants as a result of runoff or pollution. These compounds can be harmful when ingested.
Pesticides – As with metals, these are a common hazard in modern agriculture. Since hemp absorbs almost everything it touches, plants grown using pesticides often retain significant amounts of them. Pesticides are essentially poison, and should not be ingested.
