Posting for harm-reduction / curiosity. I’m not using this batch anymore, just trying to understand what may have caused this reaction and whether anyone else has experienced something similar, especially in the UK.



Background

• Location: UK

• Regular ketamine user

• Usually buy from the same person and haven’t had issues before

• Recently my usual guy said he’s expanding and has been sending a worker instead

• I don’t usually know specifics about cuts/adulterants, so this stood out to me



Route / context

• Snorted only

• Ate normally beforehand (nothing unusual)

• Symptoms started very quickly, around 5–10 minutes



Appearance of the substance

• Instead of larger shards, it was very fine, almost glitter-like particles but looks the same as k just skinny

• Seemed to cling to the sides of the bag unusually (static)

• Felt harsher and dustier than normal ket



Dose

• Similar to my usual amount

• I did re-dose throughout the night at first (stupidly), because the nausea seemed to ease briefly when the ket effects kicked in, then return when they faded

• Eventually stopped completely



Symptoms

Nose / throat

• Burn lasted longer than usual

• Nose blocked up much faster

• Excessive drip compared to normal



Mouth / throat

• Very heavy salivation

• Constantly filling with spit

• Sensation like foam or bubbles coming up my throat

• Spitting out white, foamy saliva

• Frequent burping



Body

• Strong nausea (felt different from anything I’ve had before, almost anxiety-like nausea but much more intense)

• Felt like I might throw up

• Mild flushing

• Symptoms persisted for hours, including while trying to sleep



Mental effects

• Very little dissociation compared to expected

• Some eye-delay effects, but they felt odd and uncoordinated, not the usual smooth delayed movement I associate with ket

• Overall effects didn’t match the dose



Closed-eye visuals

• When trying to sleep, I experienced pronounced closed-eye visuals that felt atypical for ket:

• flowing / drifting colour fields

• colours blending into each other (reminded me of psychedelics rather than ketamine)

• recognisable imagery (faces, animals, objects — e.g. elephants and just random people)



Duration / resolution

• Symptoms continued even after stopping use

• Hydration didn’t help much at the time

• Eventually resolved on their own

• Felt fine the next day



basically I was just wondering whether this pattern matches:

• a known filler/adulterant

• contamination

• or something others in the UK have been seeing recently

• I initially wondered about MSG or another irritant filler due to the physical symptoms, but I know that’s not something you can confirm without testing



Questions

1. Has anyone experienced excessive salivation / foamy spit / strong nausea like this from ket?

2. Does this symptom pattern match any known fillers or adulterants?

3. Has anyone in the UK noticed similar fine/glittery batches recently?



Again, I’m not using this batch and this is purely harm-reduction and curiosity. Appreciate any informed input but please don’t use fancy words I get confused easily xx
