It is known that some of the most intense buds can give you feelings similar to shrooms.....but that really doesn't include the major hallucinations part.
I agree there are way more trippy drugs out there...
But I have had auditory hallucinations and closed eye visuals...
and although I have not actually visually hallucinated shit, if I smoke some good bud things appears REALLY different to me....So it's sorta trippy...but not really tripping....
But as far as auditory hallucinatons go I get a few of those...last night I was smoking some heavy bud...and I started hearing like the drums and flutes from old battles....
And for a real short period of time I had a deep anxious feeling that I was gonna get killed by a huge army.
