You're arguing smoking marijuana (burning it and inhaling the byproducts) is less harmful than e-cigarettes.
I highly doubt that.
Didn't that story about a mysterious rise in lung disease tied to vaping a couple of weeks ago implicate marijuana as the cause?
I heard THC technically it could indicate a lack of quality control in their products or delivery mechanism. Like bathtub gin for blindness - while alcohol isn't healthy the methanol was the actual cause. Expired vaccines have killed people for instance.
No, it implicated tobacco/nicotine based products. And it sounds like something significantly more dangerous than the usual vape products are involved. People have been vaping for years without being hospitalized their first few months of usage. This sticks out as highly unusual, regardless of your views on vape safety overall.
This is a case of particularly bad reporting. These cases are all related not to nicotine but to THC and other drugs being tainted.
