So the big revelation here is that marijuana is temporarily mind-altering? This is a no-sh**-Sherlock observation, and very different than the Reefer Madness hysteria on this thread.
“So the big revelation here is that marijuana is temporarily mind-altering?”
In a manner consistent with the point of the article - that it can produce psychotic breaks (such as hallucinations or pathologically unrealistic beliefs), which can produce incoherent or criminal actions.
The full extent of those effects is not likely to be accurately measured, recorded or recognized.
“This is a no-sh**-Sherlock observation”
Marijuana is a mind altering drug - that can produce undesirable and criminal behaviors.
In most people, at typical doses, those risks are negligible, in high risk populations or at very high doses (like those made possible by extracts), increased undesirable outcomes are reliably predictable.
