I've had so-so luck with hash in vapes.. It will work, but faster resin build up than with buds.. So thats a factor. It will work better unpressed, mixed with a little bud if you want to go with that route. For smoking, I would just press it... It's really great for edibles or tinctures. Much easier to gauge dosing.
If you are just worried about efficiency... The vape is king. But, certain cannabinoids don't vaporize well. I believe CBN doesn't... Which helps some people with pain.... I love the taste of pressed hash, but I still intend to use most of my kief for tinctures... It's the best efficiency I've found to take care of my health issues.
Unpressed it is pretty harsh smoke.
