Medical marijuana proponents have filed another bill in the Delaware legislature to legalize medical use of the drug.

This is the third straight year Senate Majority Whip Margaret Rose Henry has introduced medical marijuana legislation and Henry says she is optimistic.

Rep. Helene Keeley, the House co-sponsor, says unlike California and 13 other states, the bill would not permit people to grow their own marijuana.

Senate Minority Leader Gary Simpson, R-Milford, says he is undecided, and concerned that marijuana is a gateway drug that leads to the use of more dangerous drugs.

The bill would allow possession of up to six ounces and Delaware's health department would issue identification cards for patients and providers.
