People who are spun but not tweaking tend to be pretty sociable and easy to get along with. People who think users go feral the second the devil's ice is in their system have no fucking clue what they're talking about.

In my (very, very extensive) experience though, no, meth doesn't have any spiritual applications. People who are high will think it does due to their drug-induced euphoria, mania and/or psychosis, and the paranoia you tend to develop from sympathomimetic drug abuse leads you down /x/ish lines of thought. Especially if you start experiencing hallucinations after you've been awake for four days.

Anybody who thinks stimulant psychosis is some sort of spiritual awakening is either psychotic themself, or has very little exposure to psychosis. It's not a unique form of insight, it's a fucking shitshow.

Why can't it be both? As above, so below

In a sense it's both. But at best it's 10% unique perspective and 90% incoherent, debilitating shitshow, with a complete inability for the person to distinguish between the two.

That's a best-case scenario, it's usually closer to 2% and 98%.
