Could i develop asthma from smoking weed also?

Possibly: Technically speaking, asthma is usually an allergic condition. That is, the symptoms develop due to allergies to pollens, mold, etc. However, about 10-15% of asthmatics are non-allergic, and tobacco or marijuana smoke can both make such symptoms worse. The smoke from marijuana is typically non-filtered as well, making it particularly dangerous to the lungs.

Yes: Smoking anything can give you asthma, or more commonly exacerbate an underlying asthma that may have been ok before. Think about it - whatever you inhale, goes right to your airways and irritates them!
