The FDA is accepting public comments before proceeding with a decision as to whether international restrictions on the drug should remain in force.
Use this page on the NORML site to send a pre-written (but editable) comment to the FDA (and, of course, they’ll offer you a chance to make a donation to NORML while you’re at it).
Comment directly on the FDA’s site. Note that they are considering several drugs, so be sure to specify that you are talking about cannabis, unless you have an opinion about the other drugs too. If you wish, you can go to the NORML page first and take a look at their pre-written letter to get talking points.
Comment period closes October 31 - don't wait!
