Joy,

According to Hale '97, page 371:

LSD is a power (my note: perhaps it is "powerful?) haalucinogenic drug.
No data are available on transfer into breastmilk.  However, due to its
extreme potency and its ability to pass the blood-brain-barrier, LSD is
likely to penetrate milk and produce hallucinogenic effects in the
infant.  The drug is definitely CONTRAINDICTED (Dr. Hale's emphasis).
Maternal urine may be positive for LSD for 34-120 hours post ingestion.

Pediatric concerns:  None reported via milk, but due to potency,
hallcinations are likely.  Contraindicated.

Yikes!  Hope that helps!
Kathy
