How to use Regression to solve this task


I am new to statistics and in uni we use SPSS to solve statistical problems.
I have difficulty to orientate how to solve a problem with Regression by using collected data from multiple sources.
The task is the following:

Is there a connection between using legal and illegal drugs(alcohol, cigars, drugs) and sexual orientation. The hypothesis is that people who consider themselves bisexual or gay have higher risk of developing addiction n comparison to people who identify as heterosexual.
So I have three groups and I need to compare them. There are 2 independent and 2 dependent variables. Any ideas how to do that in SPSS with Regression? :)

Can you list out exactly what you are considering the independent and dependent variables and how they are formatted?
