Burning plant material at the very least still has nasty hydrocarbons and soot in it, and generally cannabis smoke is held longer than cigarette smoke. So even if it doesn't have additives like the tobacco in cigarettes, it's still bad for you. HOW bad likely depends on a number of factors. Flower vaporizers are likely on the less harmful end while vaping THC oil cartridges are likely on the more harmful side, so even among "vaping" the risk could be variable. Straight up burning flower though? It's probably as good for you as it makes your breath smell afterwards.
