No, that's not true at all. Weed, acid, mescaline, psilocybin, salvia and DXM are all very safe if used responsibly. There have been no deaths directly attributed to weed, shrooms or salvia, DXM overdoses are overwhelmingly TRIPLE C'S overdoses, there has been only one mescaline cactus-related death (an allergic reaction, isolated) and they're all safer than alcohol and cigarettes.

Don't be so irresponsible, seriously. That's how it always happens, somebody abuses their shit, public uproar, laws are passed and the public forgets about it without another thought. Don't make that shit happen to fucking dex.
