A bill, ironically named 420, has been put before congress. This bill would federally legalize marijuana, tax it and regulate it in a similar way to alcohol.
This is not the first time a bill to legalize pot has been put before congress. This is how ever the first time with the international climate of cannabis changing. This one might work. Canada has gone fully legal. Anywhere you can smoke a cigarette you can smoke a joint. On a international level talks of having cannabis down graded from level 4 (having no medical value) to level 1 (minimum risk) are on the table.
All we can do is hope for the best and continue to show the world that this plant is not harmful.
