The correct answer to this open question is the following.
Although it seems that the question is incomplete because does not provide all the context and reference, we can comment on the following.
We are talking about creating a campaign against ATOD abuse, that stands for Alcohol, Tobacco, and Other Dr*ug Abuse.
Although the question does not provide any list of barriers and media messages, we can develop educational campaigns to help members of the community to avoid or overcome barriers such as shame for their condition, shyness, prejudices, and denial.
Possible campaigns might focus on avoidance of underage drinking or teen substance abuse, prevention of driving under the influence, teen driving safety, validating or refuting perceptions of norms regarding drug use, or promoting a drug or teen court advocacy program in your community.
I would suggest using these campaigns creating short and powerful messages that can be sent via social media so young people can see them. Not so much on traditional media because youngsters spend more time with their mobile devices and chatting with friends. So I would focus these short messages on causes and effects; yo do this the real consequence can be that.
