For emergencies only, probably depending on what your doctor says. Other than that, it's a no because you dont need to do drugs with any medication at all. It's really bad damage to your immune system and your lungs and other body parts. Even if your offered from a friend or a family member, you shouldn't do it because it will change your emotions and how you act with people.
This is what I think about using drugs other than medical reasons. I hope this helps :)
