Combination

Mixing Ketamine (ket) and Methamphetamine (meth)

DissociativeStimulant
Verdict

Caution

Likely to raise blood pressure, and moving around on high doses of both risks injury. Keep doses sensible, and avoid moving around much on high doses.

No unexpected interactions, though likely to increase blood pressure but not an issue with sensible doses. Moving around on high doses of this combination may be ill advised due to risk of physical injury.

Risk / Headspace

The risk here is to the experience — intensity, panic, thought loops, confusion. Physical harm is unlikely at ordinary doses. Setting, company and dose do most of the work.
