Drug info - LSD chemical variations?

[TheWorldwideTryptanem]

Now SWIM has had acid for a long time and understands the unpredictability and how trip experiences can vary with the same acid.
Now SWIM did an experiment with two friends over the past three months with three different batches of blotter all from different people all very similarly dosed. Each type was taken on at least five different occassions.
Conclusively, SWIM and friends are convinced that each type has it's own traits. Here's how it goes.
TYPE A: Nothing much too say about this acid, really strong but nothing out of the ordinary.
TYPE B: Similar in strength to the smiley's (judjed by respiratory depression and heartbeat patterns) however, in every case deeply affected the belief system (cuts you fucking deep, hard to explain). Now, SWIM knows acid does this, but these are fucking evil. Fucked a lot of people up (including SWIM) and has a bad reputation where SWIM lives.
TYPE C: Now these are always strange. They always take about three hours to kick in (misleads many into thinking that its weak) and produce normal(expected) LSD effects. However, these cause the eyes to tear and SWIM means REALLY TEAR, non-stop for most of the duration of the trip even when in a neutral mood (not laughing or crying).
Please note that no two trips were the same except for these traits.
