You just have a very vivid imagination. LSD Is LSD - it's a set arrangement of atoms in a certain structure. There's no "atom out of the wrong place that works like LSD but makes it a bit more tactile LSD". It's simply all in your imagination.
With respect , I am not so sure about this [ ^ ] ....
I feel that there are more variables to the experience than simply just the mcg dosage , set , setting , and the user's state of mind and physiology , etc ...
I suspect that the actual composition of the " acid " in the tab is also a very significant factor
I recall that during the 70's there was an abundance of different tabs in circulation in Australia - dots , domes , cones , clear lights , barrels , etc , etc , and there was indeed very significant differences between some of them that must have been due to more than just the mcg dosages . Some of it was said to have come from USA [ clear light , orange barrels , ] , and others were allegedly from Europe [ cones , domes , dots , etc ,] ...
I remember that one type was truly exceptional - " Welsh brown microdots " [ they looked like tiny squares of chopped up photograph negative , and came in between two strips of cellotape ] . These were just brilliant - no nausea , body load , jitters , or malaise at all when coming on . The first alert after an hour or so was for me on the first trip when a black and white poster started changing colours of day-glo fluro green and orange ; and the next 10 hours was indescribable brilliant visuals and ecstatic bliss , love , and cosmic knowledge .
Sadly this " Welsh " acid was pretty scarce and there was never much around , however , it certainly made all the rest [ which was also good ] look rather ordinary at the time ...
I have never seen anything like this "Welsh " acid in the decades since ...
Now , with the benefit of hindsight [ post " Operation Julie " ] , it is quite likely that the outstanding " Welsh " microdots were Richard Kemp's acid [ reported to be
the purest ever analysed in Dick Lee's book - the head Julie cop ] ; and according to " Leaf " Fielding [ " ...above the law " ] and Lee and other authors , Kemp had hit upon a method of production that did not produce any iso-LSD or other impurities whatsoever ....
Kemp's acid was said to be better than that produced by Sandoz ...
The Julie cops analysed the tabs of the time in Britain and discovered that there was predominantly two types of acid getting around , although it was being packaged in a variety of ways - [ dots , domes , cones , microdots , etc ] ...
One type contained iso-LSD , the other had no iso-LSD at all and was the purest ever to be analysed anywhere in the world , [ inc Sandoz acid ].
I have read somewhere [ Psychedelic Chemistry , M. V . Smith , I think , and elsewhere ] that the presence of iso-LSD is suspected to detract from the " cosmicity " of trips ...
Therefore , as Ismene suggests - LSD is LSD ...
BUT , it is variable in it's effects due to factors other than merely mcg dosages ...
There are in fact other variables to be considered [ I believe ] , including purity and the presence of iso- LSD .
