Specifically THC/ cannabis, smokers do it, why cant vapers? Why cant I? Being someone who lives 24/7 with chronic pain.
I agree, knowingly doing that, would be insane.
Subjective, it's nobody's business.
Most people use regulated mods, they might shorten the life of the mod, or batteries, but it's not inherently unsafe. Most people use stock coils, they do not rebuild, they might install an inappropriate stock coil, but they learn quick, because they end up with a flat battery (very quickly) and suffer poor vape performance.
That can and does happen with closed systems, it's not exclusively an open system problem.
As previous reply.
Goes on, I agree, but the vast majority know what do, and the vast majority of vapers don't use replaceable batteries, they are built in, to the device.
Most vapers have never been near a mech.
A huge (and I do mean huge) majority of vapers have never been near, nor handled or used 72mg nic.
