Can I Vape without Inhaling ?

It is posible to draw the vapour into your mouth and then exhale and still absorb nicotine if required. The capiliaries in the mouth will absord nicotine particles and you will still feel the benefit. Its not necesary to inhale to your lungs it is optional but saying that as most vapers come from smoking inhaling to the lungs is often a habit that has been developed over time.
