DENVER (AP) — The federal government has reluctantly agreed to let Colorado be the first state to collect taxes from the legal sale of recreational marijuana, but it has also made clear it doesn’t agree with the move and may try to stop it, if isn’t tightly controlled.

Instead of keeping a low profile with the money, however, some Colorado lawmakers are wanting to use the millions of dollars they’ve collected from pot sales to seek matching federal funds to keep kids of drugs.

The plan calls for transferring $3.5 million from the state’s marijuana cash fund to its general fund and then sending the same amount to a state department that would apply for the federal match.

Supporters say the move shouldn’t cause any concerns, it simply acknowledges and avoids potential conflict.
