I really enjoyed a triple hit of weed, whisky and pipe tobacco during my most recent acid trip, but this was some time after the peak had passed. I think it's crucial to go into a trip without a fuzzy head, whether from weed or booze. I once took some Hawai'ian baby woodrose seeds (which contain compounds related to LSD) while already tired and a bit drunk after a night out, like some sort of total imbecile, and had one of only two genuinely bad trips I've ever had.
Mild to moderate poppy buzz this evening. It's a good high when you still have to keep your wits about you as it's not actually impairing unless you do a silly amount of it.
