I`m a big fan of legalising Cannabis, just like any other person on this forum.
Though agree or disagree, smoking Cannabis may have implications on some people, especially dumb people... This is a topic still under discussion, but the point is the government are afraid of certain things about the stuff. I can control my smoking and I hate the fact its illegal and most of all I HATE silently and illegaly smoking my spliff when drunk people are breaking hell lose everywhere around me on the streets!!
Gay marriage on the other hand has no implications. How selfish are you to say they can`t be married. They want to live their life together, they should be able to get married and share their property and get what "belongs" to them in a divorce. There are no valid reasons to say this can`t happen unless your anti gay, and your not gonna get far like that. If men want to be with each other that means there are more girls available for the straight men
If you still have a problem, maybe your very secretly gay
So in my opinion gay marriage should be legal and so should cannabis.
