On a side note, in the past SWIM has had lots of LSD laced with either atropine, scopolamine, or hyoscyamine. He could distinctly feel the tropane alkaloids in the acid. These alkaloids are active in the microgram dosage level and so they easily fit on blotter hits along with LSD.

You can tell if your acid is laced with tropane alkaloids because it causes the following side effects:

* Slightly reddish face, arms, etc. (Pure LSD tends to make you pale, not more reddish)

* Extremely dilated pupils more so than LSD normally does.

* Difficulty urinating (you might feel the need to urinate but little if anything comes out)

The combination is quite nice. It's much more visual than pure LSD, much more trippy, but these types of blotter acid are dangerous to take in large doses.

SWIM has run across acid laced with tropane alkaloids maybe about 50 times. (He's used acid over a thousand times in his past.)
