The topic..weed

I dont wanna hear no bs about how great it is. Or how it is safe. I just want a yes or no.. do you think weed is addictive..or can be addictive and do u think it can actually alter your moods negatively.. how do u prove to somebody it does when they don't believe it does.. they think it does them good and helps

I can't record them cause it seems like they are always high. He wakes up everything is fine he goes outside has a cig comes in an usually packs a bowl goes outside smokes. Before he goes anywhere he makes sure he has his shit. Or/smoked prior. I bring it up.. he denies it an says I don't smoke as much as I use to. But the days where he runs out. Has nothing he's legit but sometimes he'll get owly then scrapes his pipe puts it in foil which he puts it in his bong an smokes that. We dated last year an he stopped in the beginning.. he was legit the sweetest. Everything I ever dreamed of. But then he started back up.. ah that's when the paranoia an accusing me started.. he is legit always paranoid. Questioning everything all that.. but he denies it's the weed
