Verdict

Unsafe

The DOx class as psychedelic stimulants have the potential to mask the effects of DXM and could lead to redosing to an unsafe level. DXM can also potentiate DOx resulting in an unpleasantly intense experience.

Risk / Physical + headspace

This combination carries bodily risk and can go badly psychologically. The headspace part often arrives first and makes the physical part harder to notice.
