20. Drug addiction is preventable to a certain extent. Drug use tends to be somewhat glamorized to people who are feeling low or come from challenging backgrounds.

While knowledge is power and we can spread awareness of the epidemic, it does not necessarily mean it will be prevented in every case, but hopefully in many.
