DENVER (AP) — Marijuana taxation brought the Colorado Legislature to a standstill early Saturday, with the House giving up and heading home without voting after the pot debate stretched past midnight.

The standstill was not exactly caused by the bill to tax pot more than 30 percent, though Republicans were in the middle of trying to lower the tax rate when the House stopped work. Instead, the breakdown came as a result of frayed nerves after long, divisive debates on unrelated measures, from a renewable energy bill to an education funding overhaul.
