Marijuana is a gateway to suicide by fire?
Yup. Get toasted, then get roasted.
Via whatever agent of choice which followed the original tag to genetic code area, be it cannabis, booze, heroin— all receptor mediated and brought on by dependency cycle. Quite well documented actually despite all attempts to ignore the data and the studies. These types of festivals (Burning Man in particular) attracts a heavy cannabis crowd, and a lot more. So it could have been acid, for that matter. But the receptor process remains the same, just different receptors.
Some people run for an endorphin high (a uh, natural high so to speak), and others just keep looking for more receptor satisfaction— the “gateway” allusion.
This case, could be a depressogenic response to chronic alcohol along with any of a dozen agents, including cannabis. Suicides are way up— even among bankers (stoned, paranoid, or otherwise). Deo Vindice.
