Should i help him, Or Not.?

So, i recentley found out my ex does ecstacy. He's not like a ex that barely became an ex. hes an ex from long time ago. We were close back then. But we don't talk to each other anymore. When i found out it kinda idk, i guess suprised me. And it just made me feel bad for him. idk anything about drugs, and i've never tried them but i do know people do get addicted. I dont know how long he's been doing it. But it just made me somehow help him out. i'm no therapist or anything. But idk, i'm wondering if the person wants to stop they will right? but then again if i do try and help him out its gonna be kinda akward because we havent talked in so long. Should i just not?? ...
