I need the weed for my MS but it's hurting my lungs so I need to get a vape. But I have two (prolly dumb) questions (sorry):

1. When I look at these things (da Buddha, for example), they seem to be made in part of glass, and that worries me; are they dangerous? can you get hurt if the glass shatters? Knowing me, that's what would happen (my hands shake); and

2. Does using a vape really help protect your lungs?

I have really bad pleurisy.

thanks!!
