The reason for this is because combustion releases a toxic cocktail of carcinogenics and carbon monoxide. Many people tend to associate those affects with those from the herb itself.

The reality is that desktop vaporizers can cook very efficiently when they are preheated and loaded properly.

The problem is that one will never fully appreciate the affects from dry vaporizing unless they fully detox from combustion by not smoking (vaporizing exclusively) for a few weeks to month. I made the switch to dry flower vaporizing a decade ago and I still smoke socially with friends, but I hate it - the smell, the taste, the feeling, etc.

Dabs are concentrated and extract faster than most dry flower vaporizers which is why they can often work, however they can also kill one’s tolerances when used in excess. I prefer dry flower vapes to avoid killing my tolerances (I also switch up my daily driver two or three times a year to avoid building up a tolerance to the same device over time).
