I am going to a weekend Psytrance outdoor party this Saturday and has expressed interest in trying acid. They've experience in psilocybin and had a very enjoyable trip in the same environment with 2 grams of shrooms. However, they'll be on day 3 out of 5 of an antibiotic (Sandoz levofloxacin, a 20.1.1 medium to broad spectrum antibiotic)course for an ear infection. Is mixing this with LSD a good idea? Are shrooms a safer substitute? I am planning on having a tab at midnight, is it ok to induldge in some marijuana during the afternoon preceeding? I will appreciate your advice greatly.
