Of course weed effects behaviour, our vibration. We can tend to overlook its pyschological effects due to the alternative social stigma attached to it. We associate it with green, mother nature, organic, relaxing, from the Earth, alternative medicine, bob marley, anti-system, anti-alopathic etc etc (which are all beautiful and viable aspects) that we can forget how majorly it can effect us as humans. Good luck with the journey!!
I know this isn't exactly advice or anything But I'm In a similar situation My current boyfriend and I are in a rocky patch and have been since about September, worst couple of months of my life. I am quite young still and will meet somebody else, and this relationship is my first serious one. I have extremely important school exams coming up in this year and need to focus on my work, but this is all I've been able to focus on. We smokes weed, all day, every day because of his parents mainly, which destroys me. He doesn't see the problem in it but I know how much it's killing his brain cells inside, I always have to worry about calling him incase he's high and will have a different attitude towards me, he's a lovely boy deep down, I just wish he didn't smoke weed, or just not as much as he does. It is a very difficult situation to be in, because on one hand, you love them and would do anything to help them, but on the other you have concerned family and friends who care more than they ever had, and want you to stay away from it all and will soon loose faith in you. I'm still struggling to deal with the fact that it'll have to come to an end, but it's what's best for me and my future.
