1. either the OP is a retard or....
2. He has his facts mixed up...
Which brings me to my next point. What he said has some truth (not about THC cutting your lungs up). In Europe (more specifically the UK) it's become fashionable of sorts for dealers to lace their shitty ass Afghani weed with powered glass. This "DANK" weed is now sold for a premium. It's very shady some people get lung damage from this stuff, sometimes from one or two exposures. Usually what happens is that the glass powered gets red hot and it microscopically burns and cuts the fucking shit out of your lungs. I remember on another site I was on, someone posted picks of this weed (he was bragging about how bad ass this shit was). It was sparkly and strange looking. I remember I told the guy it looked like some of the worst regs I've ever seen and I thought the THC crystals were sparkles or some shit. Ends up some one posted it was glass...then flash to a month later I saw a documentary on weed from the BBC and they said this new type of glass covered weed is heavily sold in the UK at a premium because a shit ton of uneducated retards are buying it in droves thinking it is dank. So that may be what's causing this urban legend to live on.
