Tuesday’s 31-0 vote sends the measure to the House, where it’s likely to draw strong support. Huffman said a similar bill passed the Senate in 2013 but died in the House because of what she called “vindictive” opposition from a representative who opposed Huffman on another issue.

Also Tuesday, the Senate approved and sent to the House two bills to limit synthetic marijuana production, distribution and use.
