“The idea of this video is to specifically reach people who are against decriminalization and to take them seriously. There is an abundance of pro arguments and content on the internet – and while they are correct, they tend to marginalize the negative effects of smocking weed. So we wanted to show that even if you think that nobody should ever smoke, you still can support a public policy approach that protects more people, than by keeping cannabis illegal. Sometimes it is annoying to hear things that don’t match what we already think. Researching our videos in depth often does the same thing to us. In this case we decided that was more important to reach people, who would not have watched another video that is obviously pro liberalization.”
