Verdict

Dangerous

Both substances cause ataxia and bring a risk of vomiting and unconsciousness. If the user falls unconscious while under the influence there is a severe risk of vomit aspiration if they are not placed in the recovery position.

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.
