It’s intended to be an alternative to marijuana. Packets that contain dried herbs sprayed with synthetic cannabinoids, the active ingredient in marijuana. They’ve filled shelves at the herbal tea and tobacco shop in Bangor for more than a year. But by Friday, they’ll be gone. “Well, we will be pulling all of the products that contain the banned substances listed by the Federal DEA website,” said the store’s owner, Christopher Ruhlin.Last month, the Federal Drug Enforcement Agency posted a notice of intent to temporarily ban five synthetic Marijuana drugs. Their decision comes after various state reports that the drugs have negative side effects like anxiety, vomiting and seizures. “I do think there are valid concerns and I think that it’s not unreasonable to say that this should be regulated. Whether we should ban it or not, I think definitely not,”It’s a restriction that will potentially hurt sales.”As a result of the ban, I’ll be sending a notice to Maine Revenue just explaining to them the sudden discrepancies in our sales because it will be substantial,” Ruhlin said.But since there’s no state regulation that bans the drugs in Maine, it could make enforcing it more difficult.”Well, the way to look at it is it’s against the law under federal law, which makes it the responsibility of the federal authorities to enforce that law. It’s not the responsibility of municipal counties or state law enforcement to investigate allegations or investigate stores that are selling it,” said Darrell CrandallUntil more research is done, Bangor stores that had carried the packets won’t have them in stock.
