Labels aside, there can be no 100% pure hash. When it approaches over 50% THC, it becomes oily and viscous- this is hash oil. As you get more and more pure, it will eventually become 100% cannabinoids, a reddish-brown mix of various cannabinoids. The purest hash out there will still contain plant matter that has tar and carcinogens released during smoking.

Short answer is no, a vaporizer is still far healthier.
