Mercury Levels Flag Colorado Medical Marijuana Recall

More medical marijuana sold in Colorado has been recalled after state laboratory tests found potentially unsafe levels of heavy metals.

According to a November 18 announcement on health and safety from the state Marijuana Enforcement Department, medical marijuana flower, shake or trim from First Class LLC tested positive for high levels of mercury, a toxic heavy metal found in plant soil or growing nutrients.

“Consumers who have these affected products in their possession should return them to the medical marijuana store where they were purchased for proper disposal. Consumers who experience adverse health effects from consuming the product should seek medical attention immediately and report the incident to the store,” from which they purchased the product, “reads the recall.

First Class is a wholesaler of medical marijuana, according to MED, and does not have a brand or pharmacy attached to it; the recall also did not show stores where the marijuana was sold. However, all marijuana packages have labels bearing the license numbers of the facilities where the plants were grown. The cultivation license number for First Class is 403-01609.

According to MED, the recalled lots were harvested on dates from June 13 to August 10, but marijuana is often sold months after harvest.

This is the fourth recall of heavy metal since the required test began last year, according to MED, but the first for mercury. Previous marijuana recalls for heavy metals involved arsenic, lead and cadmium.
