Two men have pleaded guilty in New Hampshire federal court to charges of selling synthetic marijuana at a convenience store.
The U.S. Attorney's office says a warrant was executed at a store in North Andover, Massachusetts in 2013, where agents seized about 100 packages of the products, sold under names like "Crazy Monkey," and "Mad Monkey."
Police say the synthetic cannabinoids are a mixture of a leafy substance sprayed with chemical compounds similar to THC, the psychoactive ingredient found in marijuana.
Mohamed Alam of North Andover, store owner, said he knew his customers were smoking the product, even though the packaging included a warning that it wasn't for human consumption. He identified Murshed Salam of Salem, New Hampshire, as his supplier, who sold the products at a gas station.
Both men await sentencing.
