Don't be so quick to judge, some people enjoy the DXM buzz. People have been doing it since cough syrup first came out. Recreational drugs don't make people losers, addicts, or murderers. Anything in excess is bad, but moderation is the key.
I tried DXM once. Projective vomitted 2 hours later. The buzz was nauseating at best. Very shifty visuals, audio sounded wavey. I sat in one place for 4 hours, thinking to myself. Like most other disassociatives, I found it quite disappointing. I'm a fan of stimulants and more social drugs, I hate getting intoxicated and just sitting by myself. Kinda similar to being drunk and a little nitrous. Something I probably won't try again, and if I do, I'll be sure to get gel caps.
