Tincture vs vape/smoking

Hi all! I am new with really figuring out what medical marijuana products are best for my severe depression - Thank you all for being here and please be patient with my questions. While I’ve had better luck getting a strong effect with vaping, I would prefer to use a tincture long term, to avoid any lung issues. What do you all think? Can tinctures or edibles (not in PA dispensaries obviously!) be just as good for depression? Secondly, is buying my own vaporizer significantly safer than using vape pens? Thanks so much - I’m a real newbie to MMJ!
