Some time ago SWIM unintentionally took 1 blotter of LSD while tripping on 1,5 gram of DXM and found effect rather interesting. So, he took a little deeper exploration of possibilities of combining LSD and various tryptamines and phentylamines, for example LSA, DPT, 2C-I. As a result there emerged conclusion: dissasociative effect of DXM in some bizare way potentiates psychodelic and, especially, visual aspect of trip on these substances. The feeling is, that DXM "opens" some new susception capabilities. For example, when combining acid with 1 gram DXM, effect from 1 hit is far more overwhelming than 5 hits of acid alone. Or 20 miligrams of DPT (snorted) + 1,2 grams of DXM results in MASSIVE visual distortions. Even 150 miligrams of DPT can not compare with this. Please, share your findings in this area!
