If the "sand" is being set on fire, won't it melt? It'll just turn into mucus then, which can be coughed up easily.

Anyways, Silicosis happens in mining operations, building sites etc. where silicon is present. The difference here is that the workers are breathing in huge amounts of the particles in the atmosphere. We are smoking them, I'm pretty sure it's not as dangerous as it's being made out to be.

That's even if the dust is sand or silicone.

Silica is present in the cell walls of many plants, Cannabis included. So wheither your grass is "spiked" or not, your smoking silica and have been your whole toking career.

"To the naked eye it looks like high quality cannabis, but when smoked it leaves a residue of fine sand. "

Even if that residue get's in your lungs, it will ge caught in the mucus.

The whole thing is a joke. With no evidence at all people are scaremongering.
