have i used the verbs correctly in this sentence?

Question

El problema de drogadadiccion comienza en la casa familiar porque el primer factor que contribuyen a la drogarse es la falta de comunicacion familiar.

Answer 1

One point would be, not verbal, but to remember your accents and you have a spelling mistake also with : drogadicción.

Another I can see is that you are speaking about the primary factor (singular) but you have used 'contributes' in it's plural form.

Hope that helps somewhat
