Im kinda doing the same. Cant say I always do. If im very hungry after a party and only the nearest gas station is open, i grab a snickers.
But what kind of active action are you talking about? Not using facebook seems like a legit boycott of it. Is it actively speaking about not using it and informing other people?
Yes. And stop the criminalization of being a drug addict/user so it can be easier to end the viscious circle. Help the people to get off of it and dont punish them for using it.
