DXM is the weakest one in the Dissociative drug category. I love it. And i hear PCP and Ketamine, fuck u up pretty bad mentally, and psysically. No DXM isn't harmless, but its still a great trip, and low risk of bad things happening. So know your doses, and NEVER go beyond 1000mg, or mix alcohol with DXM. You'll be good. Enjoy the trip
