Its like any other addiction in this world. When you start abusing it, it starts abusing you.
I smoked ganja for 10 years, 7 of these, I smoked it like the normal person smokes cigarettes. That's when it became really detrimental to my mental health.
People who haven't had bad experiences with ganj, are either in denial or they haven't abused it. Its one of the two in my experience.
My advice - come off it completely. I came off it for 2 years, it took at least 12 months for me to feel like there was a slight change in my mentality. I didn't think it was enough of a change to blame the ganj for exaggerating my anxieties. So I waited a while longer, then I went back on it, and it wasn't until then, I realised exactly what it done to me and how much it did affect my mentality and exaggerate my anxieties x100. It's bad news....if abused
I'm off it again, and now seeing and feeling a massive difference. I think I was part of the 'weed denial group' for a long time. If I hadn't have went back on it to see what it really does to me, then I would still be in denial. The first week is the hardest to come off it, after that, you're laughing, 7 days isn't a long time. You can do it
