The disease of addiction is complicated but research has found that certain genetic traits and factors can increase or decrease substance abuse by individuals. Certain biological differences influence the reaction one person might have which differ from another when using addictive substances. Environment also is a component of substance abuse by how easily addictive substances can be found or bought. When substance abuse and dependency is not recognized in its early stages, the more difficult the situation becomes. Because addiction is a disease influenced by genetics and environment, we must remove the stigma, shame and silence of being an addict to open the door for more recovery and sobriety for the ones we love.
