LSD is LSD - no matter how pure.
I really have to disagree w/ you here. LSD has many analogs, some of which are active in man at similar microgram quantities. Just because one sets out to manufacture lsd doesn’t ensure the final product is actually LSD-25. According to Shulgin, “Repeated recrystallizations from methanol produced a product that became progressively less soluble, and eventually virtually insoluble, as the purity increased. A totally pure salt, when dry and when shaken in the dark, will emit small flashes of white light.” If the cook did not recrystallize (aka: wash or rinse) to the totally pure salt, the subsequent “LSD” could very well be one of its analogs. During the “summer of love” in the late 60’s it is believed the “orange sunshine” acid was in actuality an LSD analog, ALD-52.
If its cut with anything active enough to fit on a blotter, you'll know you had DOB or 5-MeO-AMT, not "amber" or "fluff".
As stated above, a substance other than LSD can be present and fit on a blotter. I doubt anyone would consider the presence of any LSD analog as a “cut”, but one could very well experience noticeably different “trips” without ever ingesting any of the compounds you have mentioned.
It’s well documented purity plays an important role in the lsd experience. Here are just a few paragraphs I grabbed from an Eisner article.
“Timothy Leary, who realized that impurities were a threat to the spreading psychedelic revolution, uttered prophetic words of warning at a Senate committee hearing in 1966, in exchange with Teddy Kennedy:”
“Augustus Stanley Owsley III, unable to obtain any pharmaceutical LSD, began to manufacture his own - first in Los Angeles in '65, then in nearby Point Richmond in '66. Owsley's fellow alchemist, Tim Scully, admitted to me that the 1965 batch was impure, but claims that Owsley and he perfected a purification process in 1966. Many who used both Sandoz and Owsley - the latter came in tablets of purple (Purple Haze) and white (White Lightning) of 270 micrograms - say that Owsley acid was less mystical and had more stimulant side reactions than the Sandoz product.”
“LSD is a translucent crystal; this was a black mess. Thus, the first underground LSD was also the first impure batch, and its distribution may, somewhere, have incurred the first unfavorable consumer reaction.”
There are numerous sources that all confirm color changes related to crystal purity. Why then is it so hard to believe cooks would label their end product accordingly?
As posted previously:
TYPES OF CRYSTAL
Needlepoint-very pure(95% ) white powerdery crystal…
White Fluff-Very pure(95% ) white light flakes of crystal….
Silver-Good and clean(85-90% )-light greyish crystal…..
Amber-Decent(70%?) This crystal varied from a light amber color to an almost dark brown color.Was always available.One batch called quadricept amber was the color of light honey and was very good.
Lavender-(60-70%?) light purple to almost black colored crystal. Like amber it varied batch to batch.
TJ(tornado juice) - purity unknown. I seen this shit in about four different colors…
Champagne-(50-60% ) black crystal…..
This hierarchy of crystal purity is well known (especially in Dead family circles) and is directly based from the physical condition of the resultant product. It’s not just a label tossed in for the hell of it nor is it some rumor passed on via secret parking lot discussions.
