Ketamine is probably the least harmful, PCP the most, and DXM somewhere in the middle, but this is a rough guesstimate. Nitrous oxide is brief acting, but it too may be dangerous; it is also known to damage both central and peripheral nerves by depleting vitamin B12

All dissociatives are harmful. But, some are moreso than others, I guess. Though, the Olney's Lesion theory may not be correct.

There's still a lot of unknowns here. Nobody has ever seen Olney's lesions in a human brain. It could be that this damage only occurs very rarely, to people with underlying neurological disorders
UserName AlphaNiner Reviewed by UserName AlphaNiner on . Why is everybody so into DXM? I use to love DXM but after awhile I didn't really feel like drinking a whole bottle of cough syrup just to get high. Why don't you guys try some K? Its alot easier to take and you get better effects. Two lines of K and I am fucked for around 5 hours (Seems like 5 days). Rating: 5
